Vuatercourse Studies

Background

At the time the Bank Group was setting up the working arrangements forthe study (June 1964) the LIP consultants were already at an advanced stage witha Regional Survey of the Sind which was due to be completed in 1965. Includedin the LIP survey were some 60 watercourse studies designed to obtain detailedbasic data on farming conditions in the Sind. It was agreed with the Govern-ment 1/ that the Bank Groupts consultants would set up a similar (but smallerand shorter duration) arrangement in the Punjab so that the combined resultswould provide a fairly good coverage of the irrigated plains and reasonablysound basic data.

This annexure contains in brief summary form some of the findings ofthe two sets of watercourse studies. Fuller details are given in the LIPReport 2/ and IACA's Comprehensive Report and Supporting Documents 3/ fromwhich these notes have been extracted.

A watercourse is the basic unit of the irrigation system and in thesestudies is defired as the area of land served by a fixed outlet from a canal ordistributary. 4/ Farmers may live within the watercourse, or in a nearby vill-age, and often have land in more than one watercourse. It is the most suitableunit for studying on-farm irrigation practices. The objectives of the twostudies were similar; namely, to determine at first-hand the present state ofagricultural development, to provide basic and reliable data for the formula-tion of development plans and to obtain a base from which the progress ofdevelopment schemes could be assessed.

The main differences between the two sets of watercourse studies werein their size and duration. The LIP watercourse studies extended over some18,170 acres in the Sind (representing 0.15 percent of the official CCA of theRegion) and were conducted over four seasons. The IACA watercourse studiescovered some 6,200 acres in the Punjab (0.03 percent of the CCA) with a partialcoverage of a further 3,900 acres, and the period of study was less than twofull seasons.

The study areas in the Sind were chosen to represent each of themain geographical areas as well as the major canal commands. Within the twelvecategories established, a stratified sampling technique was employed to select60 watercourses for detailed study with an average size of about 300 acres.

ANNEX 2.1Page 2

A different procedure was adopted by IACA in the Punjab. Ten represen-tative sample areas each covering 500 square miles were delineated. In each ofthese sample areas two watercourses, sited wherever possible at the head and tailsections of a distributary, were selected for detailed study. This provided 20watercourses for detailed study with an average size of about 300 acres.

"lithin the selected watercourses (60 in the Sind and 20 in the Punjab)detailed records were made of all farming activities. For the watercourses asa whole these were made weekly or fortnightly but within most watercourses onefarm was selected on which daily records were made of all activities. Thesevoluminous detailed records were analysed to provide information on all aspectsof farming practice including water management, frequency and methods of culti-vation, physical inputs, yields, farm costs and some aspects of farm management.Some of the principle findings or observations emerging from these studies areset out below.

Land: In the irrigated areas of both regions about three to fourpercent of the area is occupied by roads, canals, villages, etc., leavingavailable for agriculture about 96 to 97 percent of the gross area. In thePunjab more than seven percent is also excluded, mainly because of salinity.The average culturable waste in the Sind was even higher at 19 percent. Therewere marked differences in land tenure between the Punjab and the Sind. Theformer is characterized by small land owners predominantly farming their ownland. By contrast, the Sind had larger land owners generally farming the landby share cropping tenants.

Soils: Chemical and physical analyses of the soils of the Punjab sug-gested that quality varied widely. An attempt was made to assess the effects of

soil quality on yield by grouping soil types into four major categories. Yieldsassociated with these showed that only the poorest class of soils gave consis-tently lower yields. Since the distinguishing characteristics were heavy tex-ture, marked salinity and alkalinity, it was concluded that these were importantconstraints. In the Punjab some degree of salinity was present in 77 percent ofall soil profiles examined and 28 percent of the samples showed some degree ofalkalinity. For the Sind, where less precise measurements were made, it wasevident that salinity in its extreme form was a very serious constraint onproduction. It was also concluded that these constraints could be reduced underconditions of better watering and controlled water tables.

Water: Cropping patterns in both regions were markedly influenced bythe times during which canal supplies were available for irrigation, the majordistinction being between perennial and non-perennial supplies. In the Punjab,some non-perennial canals supply water for short periods in winter. This, com-bined with the greater prevalence of fresh groundwater in the Punjab and itsexploitation by tubewells and Persian wheels, tended to obscure the differencesin the cropping on the perennial and non-perennial canals, which is very markedin the Sind. Comparisons between annual cropping intensities (though for dif-ferent agricultural years) indicated an overall average of 123 percent for thePunjab and only 88 percent for the Sind. The studies showed that there was aconsiderable range of intensities in the Punjab from 65 to 175 percent.

ANNEX 2.1Page 3

Both the Punjab and Sind investigations provided evidence of widespreadunderwatering. In the Punjab there was only limited evidence of higher yieldsresulting from higher applications of water alone. The Sind studies showed thatincreased water supply up to 20 inches in the case of wheat gave increased yieldbut, beyond this level, there was no further increase due to water alone, andyields actually declined. The general conclusion appeared to be that underprevailing conditions timing and regularity of supply is at least as importantas the total amount of water.

Physical distribution of water on all watercourses is frequently com-plicated and inefficient. The LIP group estimated for the Sind that adoption ofa rectangular field layout plus better watercourse maintenance would make 17.5percent more water available. In addition, the studies indicated that there wasconsiderable tampering with and blocking of outlets, together with other irregu-lar practices. This was done mainly during the sowing season when there is apeak requirement for irrigation. The larger farmers frequently received addit-ional supplies and, conversely, the more numerous smaller farmers received areduced supply and suffered accordingly. The hazard of irregular supply isalways present. Because of the uncertain and short supply, farmers deliberatelyplan to underirrigate employing extensive rather than intensive practices.

Labor: In both regions, the studies report hidden unemployment aswell as seasonal underemployment of labor. There is a considerable reserve oflabor available to meet the increased demands of higher cropping intensities,especially if the underutilized family labor is included.

Livestock: Only a very small percentage of farmers had no workingbullocks. In the Punjab the average cropped area per pair of bullocks was 12.5acres. The comparable figure for the Sind was 16 acres. Between 20 and 50percent of the annual cropped area was devoted to fodder crops in the Sind. Thecomparable area devoted to fodder in the Punjab was nearly 60 percent. Malnutri-tion amongst young and unproductive zebu cattle is prevalent in both regions.Stock density was higher in the Punjab at 505 animal units per thousand acresCCA compared with 379 in the Sind. The total annual amount of TDN fed to live-stock averaged over 3,800 lb. for the Punjab compared with little more than3,000 lb. for the Sind. While it appeared that the feeding of productive animalswas adequate, at least from the Punjab studies, there was inadequate knowledge ofTDN requirements for work animals. Even the higher figure of 3,800 lb. TDN aboveobscures the fact that the protein constituent fluctuates widely and is often lowfor extended periods, and it has been concluded that this is an important causeof delayed maturity in livestock. At present no attempt is made to conserve suchprotein rich fodder as berseem, and while working bullocks and cows in milk arepresumed to be adequately fed, grazing stock or dry cows receive little supple-mentary rations and are forced to subsist on a low plane of nutrition basedmainly on grazing and browsing. Very few farms were larger than the 80-acresholding deemed to be required in the Punjab to make tractor power in place ofdraft animals wcrthwhile. (The corresponding figure of 60 acres given fromthe Sind study is surprising in the light of current cropping intensities.) Intheir conclusions on the nutrition of work animals, IACA has pointed out thatmore intensive study is needed on the whole problem of work animals, their workoutput and feed requirements.

ANNEX 2.1Page 4

Fertilizers: The LIP group carried out numerous fertilizer trials onthe main crops of the Sind. In most cases the trials were superimposed on actualfarmers' fields. These were selected for uniformity of crop cover and thereforetended to reflect better than average farmers on better than average land andwith favorable water conditions. Nevertheless, widespread underwatering wasrecorded. Average response of wheat, based on more than one hundredd experi-ments conducted on lighter textured soils, showed that nitrogen at 40 lb. peracre without phosphate gave a 27 percent increase over the control yield of16.9 maunds per acre. The increase with 200 lb. of single super-phosphateadded was 34 percent, a result similar to the long-term average obtained by theWest Pakistan Department of Agriculture. Results on the heavier textured soilswere less conclusive and yields without fertilizer were considerably lower at5.5 maunds per acre. There were indications that higher dressings than 40 lbsof N would be optimal.

Evidence for yield response of rice to fertilizers indicated that thebest results were obtained when this was applied at transplanting. Unfortunatelyto get the best results from this top-dressing demands complete water controland fields to be drained prior to application. This condition could notgenerally be fulfilled in the Sind.

The failure of cotton, as grown under present conditions, to respondto fertilizer was ascribed mainly to low plant populations. These in turn weresaid to be a reflection of the farmer's reaction to the hazardous water supplysituation and to inadequate plant protection measures.

Information from the Punjab study was less direct since no formalexperiments other than those of the Rapid Soil Fertility Testing Scheme wereavailable. These indicated that 40 lb. nitrogen and 200 lb. single super-phosphate led to a yield increase of about 40 percent. Fertilizer usage wasreported to be common throughout the Punjab watercourses. Unfortunately, IACAwas unable to relate yields directly to fertilizer applications. They pointedout that from field observation, farmers appeared to be aware of the benefitsof fertilizers especially when the amount of water was adequate with regularityof supply.

Improved Seed: The Punjab study indicated that farmers on all but oneof the twenty watercourses purchased seed of the desirable American-type cotton,thus indicating that provided the quality of seed was good and supplies wereavailable, there should be no difficulty in introducing better varieties. Inthe case of rice also, the advantages of pure seed of recommended varieties haslong been recognized. The supply is inadequate. Efforts to overcome the short-age of good seed have led to adulteration and abuses with consequent disreputeof the seed.

The studies also showed that a number of recommended wheat varietiesbred in Pakistan are being grown in the Punjab watercourses. The best yieldingof these require abundant water and rich soils or artificial fertilizer toachieve potential yields of the order of 56 maunds per acre. In practice, far-mers have made wider use of a lower yield potential variety which is describedas being suited to average fertility and irrigation conditions and this varietyaccounts for 36 percent of the total wheat acreage on the watercourses.

HaiirX 2.1Page 5

In its conclusions, IACA noted that while new varieties are readilyaccepted by the larger farmers, the majority of farmers are content to waituntil seed becomes freely available as a result of local multiplication duringwhich time they will have been able to assess its merits.

Cultivation Methods: Seedbed preparation was found to be one of themost important factors affecting germination and subsequent early developmentof grain. Because the soils of Nffest Pakistan generally have poor structure,this aspect of cultivation is of great importance. Unfortunately, no general-ized description of requirements to secure good seedbed conditions could begiven. Consistently high yields of wheat were obtained only by those farmerswho devoted considerable attention to seedbed preparation.

Other cultivation practices were shown to be of great importance inthe Sind. Higher yields both for wheat and cotton were obtained with increasednumbers of ploughings, smoothing and good standards of levelling. The magnitudeof the differences due to cultivation practices was impressive. For wheat,yield differences varied from nine to fifteen maunds per acre and cotton fromsix to twelve maunds according to the number of ploughings from one to seven.Even allowing for some interaction effects which could be attributed to otherfactors, these results iiidicate that agronomic practices reflecting managementrather than physical inputs have great effects on Yields.

Plant Population: Farmers on the Punjab watercourses were well awareof the relationship between plant population and yield of certain crops. Butbecause of their expectation of shortage of irrigation water, they were gener-ally cautious about increasing plant density. Even the highest plant popula-tions recorded both for wheat and cotton were low by standards in other partsof the world. Averages for cotton in the Sind of 11,300 plants per acre andfor the Punjab of 10,000 set a low limit to yield under existing conditions.The Sind study also showed for cotton that economic returns from the use offertilizer and pesticide inputs, were not likely to be obtained unless plantpopulations exceeded 16,000 plants per acre.

Credit: The situation regarding credit requirements was compiledfrom a sample of farmers from each of the 20 watercourses in the Punjab. Nearly64 percent of the 460 farmers in the sample were found to be in debt. Of theindebtedness, which averaged Rs. 30 per acre, about 60 percent was estimated tobe incurred in the interests of farming. No direct relationship between debtand farm size class was evident although it was observed that in the tenantgroup the debt per farmer was highest in the 0-5 acre class and lowest in thesize class of 25 acres or more. Owners and owner/tenants generally had lowerindebtedness than tenants. Furthermore, owner farmers with holdings of 15 ormore acres in the Punjab were found to be capable of generating savings. Thegeneral conclusion was that while there appeared to be an adequate supply ofshort-term credit available for working capital or purchase of small implementsunder present conditions, there was a shortage of medium-term and long-termcredit for effecting major improvements such as land reclamation, drainage,installation of tubewells, etc. Short-term credit was generally obtained fromnon-institutional sources. Better facilities for obtaining medium- and long-term credit should be made more readily available to farmers.

ANNEX 2.1Page 6

The official sources of credit were reported to be too difficult forthe smaller farmers and more particularly sharecropping tenants to use. Thedifficulties to be overcome and the procedure involved before a loan could beobtained were too great. Where the Cooperative Bank was well established, itproved to be a popular source of credit. It was concluded that the establish-ment of more Cooperative Banks should be encouraged to provide medium- andlong-term credit.

Yields: Both the Sind and Punjab studies indicated that given presentagricultural practices the attainment of high yields is a relatively slow processeven when good management is employed. Earlier discussion indicates the complex-ity of constraints which operate both in the Punjab and in the Sind. In generalterms there was no identifiable situation on the watercourses which wasunequivocally associated with high yields. Clearly, water is a generallylimiting factor, and the farmers' response has been to adopt what seems to bea limited and rational system of underwatering. There were enough tubewells inthe Punjab watercourses to provide a considerable range of water availabilitybut, except in the case of wheat, IACA was unable to show that the watercourseswith better water availability had better yields. These findings go some waytowards explaining the reasons for the widespread practice of underwatering.It is evident that within limits spreading a limited amount of water over awider area gives a higher production than concentrating that amount of water ona small area. Where farming intensities are high and sufficient water toinclude a leaching element is applied to the kharif crop, this practice isjustified. But if farming intensities are low and insufficient water isapplied in kharif to remove salt accumulated in rabi, continued underwateringwould lead to a progressive decline in crop yields.

IACA has summarized the situation as one in which multiple limita-tions are acting together, amongst them are general underwatering, deficiencyof nitrogen, widespread salinity, for some crops damaging pests, a difficultyin obtaining good seedbeds, broadcasting rather than line sowing of crops andgroundwater levels too high. All of these factors have been investigated bythe research stations, usually as single variables, sometimes in restrictedcombinations, and often under conditions better than those found on thewatercourses.

There is no doubt that additional water supplies lead quickly toincreased production, but on the evidence of the watercourse studies IACAbelieves that the increase comes very largely from increased cropped area andonly very secondarily from increased yields. In a situation where underwateringis general practice it would be surprising if other limitations were not alsoeffective, particularly since one limitation, salinity, should be rapidlyimproved by improved watering.

Uhile the use of fertilizer was fairly common on the watercourses,IACA was unable to show any uniform or striking response. Nevertheless itstates there is, in general, in West Pakistan much stronger evidence for theresponse to nitrogen than for the response to water. It seems possible thatyield increases should be associated with fertilizer combined with water -- in

ANNEX 2.1Page 7

that order -- and limited by other constraints. If this analysis is correct,there is no single input which should be expected to give dramatic increasesin yields, and it is not by any means clear which inputs should receive prior-ity. The weight of the evidence seems to favor fertilizers followed by water.There is a strong case for multiple factor experiments covering fertilizers,water delta, seedbed preparation, plant population, pest and disease controland variety. The current thinking that additional water followed by fertil-izer and other inputs is a fully confirmed order of priorities may have to bere-examined.

Management and Extension Services: Management at farm level as illus-trated by the farmers skillful allocation of limited resources appears to beadequate at the present time and with present inputs. To overcome the con-straints on the factors involved in production would eventually need a complexseries of new inputs. As this is attempted, there would be a need for moresophisticated management. The extension service should recognize this need inadvance and begin to strengthen its farm management advice in conjunction withother specialists. This role of the extension services should be recognizedas of paramount importance. The complexity and variability of the farmingproblems call for exceptional skill on the part of extension officers. IACAconsiders that identification of constraints under different situations callsfor skills which are rare in the present services and since these only developslowly, their absence may act as a constraint on development.

The surveys indicated that farmers are receptive of advice. Fromthe rapidity of the response to tubewell water, the readiness to change crop-ping patterns, the awareness that new varieties may be better than old ones,the acceptance of fertilizers and the general skill in using resources, IACAhas concluded that conservatism and resistance to change, should not beconsidered to be crippling constraints.

A. Analysis of Growth of Agricultural Output by Zones

For purposes of assessing agricultural conditions and making projec-tions, IACA grouped the canal irrigated lands having similar crop distributioninto nine agricultural zones (see Map 2). Except for Zone I, Peshawar Vale, allare in the Indus Plains. The nine zones and the canal commands they includedwere as follows:

IACA based its estimation of 1965 cropping patterns and cropping inten-sities for all canal commands on data supplied by the Irrigation Department, theBureau of Statistics, the 1960 Census and a paper by Ghulam Mohammed..7 For theSind, data compiled by the LIP consultants were used.

These data are not intended to represent the agricultural situation onany one farm, but to provide an average picture of a specific region. Withinsuch a region, variations in cropping patterns, intensities and prevailing levelof production reflect differences due to climate, soils, water supply, tenancy,farm size, use of inputs and husbandry practices, markets and processing facil-ities. Differences in cropping patterns and intensities are, however, generallymore pronounced between rather than within agricultural zones because of thegreater influence of some of the above factors as well as the respective stageof development.

The more important crops grown during the kharif and rabi seasons inthe respective zones are given in Table 1 below together with the percentagesof land they occupied in each of the seasons. Throughout this annex, both thekharif and the rabi seasonal cropped acreages take into account the perennialcrops, i.e., perennials are counted twice.

The zonal cropping characteristics are distinctive. Thus in Zone 1,the Peshawar Vale, the main emphasis is on food crops rather than cash crops.Nearly 50 percent of the cropped acreage in kharif is under maize and more than50 percent of the rabi acreage is under wheat. The greater part of the sugar-cane is grown in Zones I and IX. Rice occupies 55 percent of the kharifcropped area in Zone II, the Punjab Rice Area, and even more in the Sind RiceAreas of Zones VI to VIII. Cotton, similarly, dominates the Punjab CottonArea, Zone III, and the Sind Cotton Area, Zone V, but in these, as in otherzones, the important position occupied by wheat is clearly shown. It isnoteworthy that the areas under oil seeds, gram and pulses begin to increaseat the expense of wheat from the Punjab southwards reflecting the increasinguncertainties of rabi water supplies. The high proportion of millet grownduring kharif in the Punjab Development Area (Zone IV), is an indication ofthe farmers' preoccupation with subsistence rather than cash crops at a com-paratively early stage of development.

Seasonal and annual cropping intensities and cropped acreages ofthe agricultural zones for 1965, and those projected by IACA for referenceyears, are given at Table 2.

Real cropping intensity in each season will be the sum of the areaunder annual crops plus the area under perennials. Thus for Zone 1, the actualkharif intensity for 1965 was 67.2 percent and that for rabi was 67.7 percent,giving the annual cropping intensity of 135 percent. This high intensityresults from both large acreages under sugarcane and fruit, as well as tofavorable water supplies. Low rabi intensities for Zones IV, V and VIIIreflect the unreliability of rabi supplies mentioned earlier. Even with thelarge sugarcane acreage in Zone IX, the low rabi acreage suggests that peren-nial water supplies are not uniformly distributed throughout the zone.

IACA considers that the ultimate attainment of 150 percent croppingintensity would result from additional water supplies associated with otherinputs in all zones except VIII for which rabi supplies would continue to beunreliable. The present and ultimate patterns shown in Table 2 reflect theproposals to use water mainly for the cash crops, cotton and rice, as well ason fodder crops. Thus in Zone 1, by 1975 IACA projects a reduced acreage con-sistent with the delivery capacity for full delta irrigation. This would reduceboth the maize and wheat acreages. After 1975, however, there is a rapidincrease in intensity ultimately reaching over 170 percent.

IACA also expects a rapid increase in cropping intensity in the PunjabRice Area (II) which should achieve 133 percent by 1975 and 150 percent by 1985.The expansion for other zones, between 1975 and 1985, is the result of raisingthe irrigation application to full delta by 1985 for the quite considerable pro-portion of cropped land which would continue to be underirrigated up to 1975.Rates at which desired intensities are achieved would vary between zones,especially where underlying groundwater is highly saline. Proportions of areawith perennial surface water supply, effective precipitation and percent ofarea with good underlying groundwater for the nine zones are given in Table 3.

The magnitude of some of the agricultural problems is illustrated by ZoneVIII. Besides having no perennial water supplies, this zone is also underlain

with groundwater having TDS of the order of 2,000 or more ppm. The table also

illustrates the advantage which the Punjab Zones II and III enjoy over the Sind.Not only are they nearer the source of water, but both perennial surface water

availability and the quality of underlying groundwater are generally better.Moreover, effective precipitation is appreciably higher for the Punjab than for

the more arid Sind region.

To examine IACA's growth of agricultural production, its projections for

reference years based on its canal command analysis and its assumptions forprices and TDN value for production animals, were apportioned between the ninezones. From these, values of GPV per cropped acre were also derived. These

data are given in Table 4.

ANNEX 2.2Page 9

Striking zonal differences in GPV per cropped acre are shown in Table4. The low GPV for Zone VIII in 1965 can be attributed in part to the absenceof rabi water supplies and to a considerable dubari/bosi acreage (residualmoisture cropping) from which extremely low yields are obtained.

The steps proposed by IACA for the removal of constraints are dis-cussed fully in its Report. Improvements are reflected in the projected GPVper cropped acre at reference years in Table 4. As might be expected, growthwould be less spectacular for zones of relatively high initial productivity.The improvements expected for the less favored zones are more readily seen bycomparisons of compound growth for the three variables, cropped acreage, GPVper cropped acre, and total GPV, which are given in Table 5. The high overallgrowth of total GPV for Zone IX is due largely to the continuing expansion ofsugarcane from about 18,000 acres in 1965 to over 80,000 by 2000.

ANNEX 2.2Page 11

For zones with unreliable rabi supplies, but without the further con-straint of poor quality groundwater, the growth of acreage resulting fromadditional water is almost axiomatic. For zones with poor quality of groundwaterand some waterlogging, additional supply cannot be effective until such con-straints have been removed (Zones VI to VIII).

GPV per cropped acre as a measure of the contribution of all inputs,including the elimination of underwatering, is more difficult to interpret.Table 5 shows that highest yield growth is generally achieved during thedecade 1975-85.

B. Analysis of Growth Factors

In order to assess the contribution of the separate effects of waterand other inputs, an analysis was made by the Bank Group of the increments inGPV attributable to (a) water alone, i.e., increased acreage at constant yieldof GPV per cropped acre, and (b) due to other inputs, i.e., no increase incropped acreage but employing IACA's full delta yields for the various refer-ence years._V To do this, first acreage was derived from IACA's croppingintensities at reference years. Then the GPV was estimated employing IACA'scropping patterns, yield projections, and price assumptions. From these it waspossible roughly to apportion the incremental contribution of either water aloneor non-water inputs to total GPV for each of the nine zones for the referenceyears. The difference between the sum of the acreage effect and the inputseffect from the total increment would be a rough measure of the interactionbetween these separate effects. Results of this analysis for the nine zonesare summarized in Table 6.

1/ The analysis was based on Rupee values at constant prices as used by IACA.

1/ In zone VII and VIII the negative contribution from acreage (water) shown arises as a result of IACA's procedure, where underwateringoccurs, of reducing the actual cropped acreage to the full delta equivalent. This procedure results in a corresponding inflation of the GPV percropped acre without however materially affecting the total GPV.

ANNEX 2.2Page 13

The relative importance of water and inputs is illustrated by theirpercentage contribution to increments between reference years. Thus, whereperennial supplies are limited as in Zones II and IV, a larger proportion ofthe expected increment would be expected from additional water. By contrast,in all zones except IV the effects of non-water inputs on yield would besubstantially greater. Even in Zone IV the sums of input effects plusresidual or interaction would be very large once the initial water shortagewas overcome.

The observation that the residual (or interaction) proportion increasesover the successive reference years is an axiomatic reflection of the importanceof employing higher input levels after enlarging the cropped acreage in order toachieve best results.

The overall picture of development is one of higher growth of rabiacreages up to 1985 and thereafter a further rise in kharif acreage which by2000 just exceeds the former. During this period, the increased area underperennial crops is a modest one, being from about three to six million acresat a rate of growth of 1.6 percent per annum.

Analysis of IACA's projections clearly implies that non-water inputswould make a substantially greater contribution to the increase in agriculturalproduction than water alone. Even if the total residual effect were attributedto increases in irrigation supplies, the response to water would be less thanthat to inputs throughout the period up to 1985. To the extent that it can betraced in this analysis the relative contributions to the incremental GPV forthe periods between reference years are demonstrated below on the basis of thetotal CCA:

This analysis would tend to overstate the input effects to the extent that theIACA yield projections beyond 1975 are generally based on full delta irrigation.The elimination of underwatering of an average of about 20 percent between 1965and 1975 would thus be attributed to non-water inputs. However, even if allow-ance is made for this, the analysis forcefully demonstrates the importance ofnon-water inputs for rapid growth of agricultural production in the irrigatedareas of iJest Pakistan.

C. Analysis of IACA's Aggregate Production Projections

IACA's totals of GPV for West Pakistan were obtained by adding GPV forthe uncommanded outside areas to those of the nine zones and are shown in Table7 below. The separate contributions of agriculture and livestock are alsoincluded as are growths between reference years.

The contribution of livestock production based on IACA's projectionsis extremely high. However, in the Bank Group's view, as discussed in ChapterII.6, the maintenance of a growth rate in livestock production in excess of fivepercent per annum for some 20 years (1965-85) would demand a level of herdmanagement and breed improvement far in excess of current standards and dif-ficult to attain. The growth of crop production for the period 1965-85 at 5.1percent also represents a challenge of immense proportion and would only be madepossible by the best use of the interdependent factors also discussed inChapter II.5.

ANNEX 2.3Page 1

Factors Affecting Cropping Intensities

The Chapter text gives a general description of the factors which pre-clude cropping intensities as high as 200 percent, the theoretical maximum. Thetext also indicates IACA has concluded that an overall intensity of 150 percentis a reasonable indicative target for the Indus Basin. This Annex is providedto illustrate in some detail how different factors impinge on cropping intensityand why 150 percent may be regarded as a reasonable overall average.

The example used here is based on IACA's Region III (Punjab CottonArea). The first table shows the present distribution of crops between the twomajor seasons at a cropping intensity of 102 percent. The table also givesbasic data on monthly rainfall, crop water requirements, and temperatures. Thegreatest occupancy of land by kharif crops occurs during July (36 percent), andby rabi crops in December (h8.5 percent). The area under perennial crops mustbe added to each of these to determine the full occupancy of the land at anygiven month. Thus it is in November, rather than December, that the largestpercentage of the land is utilized (58.5 percent), for some cotton and maizeare still unharvested from the kharif season. If ten percent of the land isreserved in all months for livestock use, then only 90 percent is the maximumavailable for cropping. An additional 31.5 percent of the land (90 percentminus 58.5 percent) thus represents what could be cropped in November if waterwere available. Actually, as the table shows, intensity could be increased byadding acreage in both kharif and rabi seasons if adequate water wasavailable.

ANNEX 2.3Page 3

The next table illustrates IACA's conception of a feasible intensityof 150 percent under full delta irrigation. The same area is involved, and thesame basic rainfall and temperature data apply. The peak month of land occu-pancy in the kharif season would still be July, but by September the foddercrop would have been harvested and some rabi crops would be sown. The acreageunder crops would begin to build up again following further harvesting of riceand pulses in October, plus some sowing of rabi crops on land which was notoccupied during the kharif season. Such sowing could take place, for example,because the cropping pattern shows a peak land occupancy in July of 73 percent,or 17 percent below the 90 percent maximum which reserves ten percent forlivestock use.

During October and November the total land occupancy hovers aroundthe 90 percent maximum, even exceeding this slightly in November. This isbecause some cotton would not be harvested until this time, and the full rabicrop could not be planted until the cotton-occupied land has been cleared.Some wheat sowing must therefore be delayed until December, a practice whichis technically possible but results in reduced yields. Referring to the tem-perature data, the mean monthly temperature minimum drops eight degrees betweenNovember and December. One alternative is to grow less cotton and more fodderand pulses in order to advance the wheat planting date, but the economic returnsfrom this pattern are likely to be lower than if cotton is retained at theexpense of some reduction in wheat yields. Another is to increase rice produc-tion at the expense of cotton in the kharif season, but the feasibility of thiswould depend on soil and water conditions to a great extent. In the area selec-ted for the example these preclude rice as a major alternative to cotton. Theresult of considerations such as these is that kharif crops would be held to67 percent of the CCA and rabi crops to 63 percent of the CCA because of diffi-culties of fitting any succession of crops which is more economical. A constantten percent of the CCA is under perennial crops in all months. Adding in theperennials, the combined intensity of 77 percent in kharif and 73 percent inrabi equals the 150 percent which IACA has used as a design objective. Inarriving at this end result, the maximum land occupancy by all crops in anymonth, not the maximum occupancy by the seasonal crops of kharif or rabi, hasset the limits to the ultimate feasible cropping intensity, because thismeasure reflects the extent of overlapping in the succession of the differentcrops which are grown.

IACA Estimates of Cost of Groundwater Mining

The need to maintain the water table sufficiently below the surfaceto avoid salinity and waterlogging is agreed by all who have examined theproblem, but expert opinions have diverged widely on the question of whetherfresh groundwater should be continuously pumped to greater depths. TheWhite House Panel Report recommended overpumping and so lowering the watertable down to about 100 feet below ground level in order to meet the rapidlyincreasing water demand. SCARP IV is designed to permit lowering the watertable to an equilibrium level calculated to reach a depth of 80 feet nearthe center of the well field. On the other hand, in the LIP report, it isproposed that balanced recharge should be abstracted at relatively shallowlevels of the water table. Harza plan to pump balanced recharge over the longterm but with considerable periodic fluctuations of water table level in orderto take full advantage of aquifer storage.

Continuous pumping of a groundwater resource which could not bereplaced is called mining. In the Indus Plains it would theoretically alwaysbe possible to replace groundwater at some future date by pumping less thanthe recharge over a long period. Nonetheless, there is a clear distinctionbetween temporary overpumping to alleviate short-term shortages and con-tinuous overpumping for a long period. Temporary overpumping is a valuableexpedient as a means of maintaining supplies at times of lower than averageriver flows or before the introduction of surface storage projects and inthese cases the replacement of the groundwater would form a part of the generalplan. On the other hand, continuous overpumping implies no such replacementbut rather the exploitation of water in the natural subsurface reservoir asin the White House Panel Report recommendation that the water table in areasof fresh groundwater should be lowered to a depth of about 100 feet belowground level over a period of 30 years. Continuous overpumping in this wayis effectively mining, which involves substantial additional costs both forcapital installation of the tubewells and for power to pump from the greaterdepths.

The increased capital costs consist of two elements. Firstly, thecost of all tubewells would be raised as deeper installations would berequired to operate with the lowered water table. Secondly, extra installedtubewell capacity would be required to pump the mined water.

If the wells were to be designed for a final depth of water tableat the 100 foot level IACA estimates that capital costs would be increasedby about 50 percent for each tubewell compared to those for balanced re-charge at ten feet. The main items in this increased cost would be thepump housing and motor and controls; smaller amounts would be added fordrilling and the gravel pack. However, it is unlikely that the wells wouldbe designed initially for a condition which would not be applicable for 30years, particularly as IACA has projected a life of only 20 years for the

ANNEX 3.1Page 2

motors. IACA has therefore taken a lower increase of 30 percent in thecapital cost of the wells. The maximum output and hence capacity, ofindividual tubewells would be limited by the hydrological conditions ofthe aquifer regardless of whether the groundwater is mined. A typicalfour cusec well, without mining, commands about 600 acres and thus theextra capital cost for deeper installations would be:

Rs. 90,00030% of = Rs. 45 per acre

If thewater table is lowered from a depth of ten feet to 100 feetbelow ground level in an aquifer with a specific yield of 0.15, the amount ofwater mined would be 13.5 acre feet per acre which is equal to 0.45 acrefeet per acre per year for 30 years. Irrigation requirements would followthe same projected pattern as without mining and the increase in groundwaterpumping would be provided partly from a higher utilization of the wells andpartly from additional installed tubewell capacity. The increase in thedesigned quantity of groundwater to be pumped would be between 20 and 25percent for which an increase of about 15 percent would be required in theinstalled capacity. The cost of this additional installed capacity wouldtherefore be:

Rs. 90,00015% of 130% of = Rs. 29 per acre

The additional capital costs are therefore:

45 + 29 = Rs. 74 per acre

Amortized over 20 years the capital charges attributable to miningare then:

Depreciation = Rs. 3.7 per acre per year

Interest at 8 percent = Rs. 3.0 per acre per year

Capital Charge = Rs. 6`.7 per acre per year6.7

Or: = Rs. 14.9 per acre foot mined.0.45

This capital charge of Rs. 14.9 per acre foot mined compares with a capitalcost of Rs. 6.9 per acre foot pumped with balanced recharge, as derived byIACA. Turning now to the power costs of mining, IACA finds that theeconomic cost is substantially more than that of the immediate pumpinginvolved, since allowance must be included for the considerable extra costin perpetuity of pumping normal recharge from a lowered water table. IACA

ANNEX 3.1Page 3

has projected a typical unit power cost of Rs. 7.4 per acre foot for a fourcusec public tubewell pumping against a total head of 40 feet. If one acrefoot is then mined from an acre of the aquifer, the water table would belowered by about 6-2/3 feet and the power cost would be raised to Rs. 8.6per acre foot, in proportion to the pumping head. The incremental powercost in nerpetuity caused by mining the acre foot of water would thereforebe:

(8.6 - 7.4) = Rs. 1.2 per acre foot pumped

With a future recharge of two acre feet per acre and future costsdiscounted at eight percent (i.e., a discount factor of 12.5), the effectivecost in terms of power alone to mine an acre foot of water from an acre ofthe aquifer would be:

7.4 + (2 x 1.2 x 12.5) = Rs. 37.4 per acre foot mined.

A similar figure was calculated in IACA Report, Volume 3, Annexure4, "Climate and Hydrology", with different assumptions for the pumping head,economic electricity cost and wire to water efficiency. Depending also onthe assumptions for specific yield of the aquifer and the amount of annualrecharge, the power cost for mining an acre foot of water from an acre ofthe aquifer may be taken as between Rs. 30 and 40.

Clearly the most significant item in this power cost, and indeedin the total cost of mining, is the additional cost in perpetuity of pumpingrecharge from the lower levels. This additional cost in perpetuity is relatedto the specific yield of the aquifer but is independent of the depth of watertable. On the other hand, the actual power cost for each acre foot minedwould increase as the water table is lowered, and would be about Rs. 23.8per acre foot pumped with the water table at 100 feet below ground level.The effective power cost to mine an acre foot of water from an acre of theaquifer would then be:

23.8 + (2 x 1.2 x 12.5) = Rs. 53.8 per acre foot mined

The mean power cost between ten and 100 feet would therefore be:

37.4 + 53.8= Rs. 45.6 per acre foot mined

For operation and maintenance, the same unit rates may be allowedas for balanced recharge pumping. These can now be added to the capitaland power costs derived above to give the effective cost of Rs. 63 per acrefoot mined, if the water table is lowered from ten feet to 100 feet belowground level over a period of 30 years.

The variation in power costs for actual pumping of the mined waterwould make the last acre foot mined more expensive than the first. Theeffective cost of Rs. 63 per acre foot mined is the mean of Rs. 55 per acrefoot mined with a ten foot water table and Rs. 71 per acre foot mined with a100 foot water table.

Effective Cost of Mining Groundwater

Item Cost(Rs. per acre foot mined)

Capital 14.9

Power 45.6

Total Mining Cost, say Rs. 63 per acre foot

This effective cost of about Rs. 63 per acre foot makes miningappear to be about the same as surface storage when comparing the cost peracre foot at watercourse. It is also evident that the effective cost ofmining is several times that of pumping with balanced recharge.

However, apart from these economic considerations, there areseveral technical factors which would require detailed analysis before miningcould be accepted. The most important of these is the possible intrusion ofsaline groundwater down the steep gradient into the fresh groundwater zones.The extent of this hazard would vary at different sites but additional bufferdrainage wells might be necessary in order to safeguard the quality of usablegroundwater. Other problems which cculd be caused by mining would be increasedlosses from rivers and canals and diminished yields from existing wells.Finally, the construction of tubewells for mining could introduce additionalconstraints on the implementation capacity and so retard the general rate ofdevelopment in the next decade.

For these reasons IACA does not at this stage foresee a case forwidespread mining of groundwater although special cases could arise in parti-cular areas. IACA's recommendations on the policy of temporarily loweringthe water table, as opposed to mining are contained in Volume 5, Annexure 7of the IACA report and where IACA also discusses the possibility of inducingadditional recharge in fresh groundwater zones.

(i)SUMvARY

As part of the Indus Special Study, the consultants to theWorld Bank formulated proposals for the development of irrigation andpower in West Pakistan over the next twenty years. The Irrigation andAgricultural Consultants Association (IACA) were responsible for theirrigation programme, Stone and Webster for the power programme andC.T. Main for dam sites. Harza, as general consultants to WAPDA, haveevolved an elaborate computer programme which enables a development planto be tested on a monthly time basis over any desired period of years.In this study, the effects on the predetermined development programmeof a sequence of river flaws, which may be historic, random, or synthetic,can be examined. In accordance with terms of reference laid down onJune 28th 1966 Gibb, as co-ordinating consultants, were directed tocarry out, in co-operation with Harza a behaviour trial of the ILACAprogranme from 1966 to 1985 and to test the power programme against thesystem electrical demand. The results of these studies are containedin this report.

THE DEVELOPMNENT PROGRAJE

The dominant feature of the IACA programme during the firstdecade is the continued installation of public tubewells (2 to 5 cuseccapacity) which would rise to about 20,000 in number by 1975, covering11.6 million acres. From 1975 to 1985 public tubewell fields would beextended over the outstanding usable groundwater areas with the objectof achieving full integration between tubewell and canal supplies.Increasingly tubewells would be installed for drainage in saline areas,so that by 1985 an estimated total of 44.,100 public tubewells would bein operation of which 34,300 would cover an area of 18.7 million acresunderlain by usable groundwater, and 9,800 an area of 4.3 million acresin zones of saline groundwater. Projections were also made for thegrowth of private tubewells (approximately 1 cusec capacity) whichindicated that about 48,ooo would be in operation in 1975, declining to25,000 in 1985 as they become superseded by public wells. Surfacestorage facilities are provided during this period by three mainprojects, the Mangla Dam (4.5 MLF) in 1967, Tarbela Dam (8.6 MAF) in1974 and Selwan/Manchar (1.8 MAF) in 1982. Other minor schemes arealso anticipated, including a reservoir at Chasma in 1971. Canalenlargement is only applied to a limited area in the first decade, about0.9 million acres, but subsequently takes the leading role and by 1985 afurther 5 million acres are developed.

The power programme envisages a steady growth of thermal powerin the South and hydro-electric power in the North. In 1975 the minimuminstalled capacity is approximately 2540 megawatts, of which thermalstations contribute 1660 megawatts and hydro stations would provide aminimum capability of 880 megawatts, from 2 units at Tarbela, 6 at Manglaand 6 at Warsak. By 1985 thermal capacity will have risen to 3800megawatts and minimum hydro capability to 1700 megawatts with the

installation of 2 more units at Mangla and 10 more units at Tarbela.

THE METHOD OF ANALYSIS

The Harza computer programme is essentially a numerical modelof the irrigation and power delivery system of West Pakistan, incorpor-ating all the major physical constituents, rivers, link canals, canalcommands, reservoir and power installations, in their correct geograph-ical layout. Into this model is fed the data of the analysis, whichfalls into six main categories.

1. Values for the physical components of the system,such as canal size, reservoir capacity and installedtubewell capacity.

2. Assumptions regarding groundwater hydrology.

3. The sequence of monthly river flows entering thesystem.

4. Monthly irrigation demands at the watercourse.

5. IMlonthly power demands and the characteristics ofgenerating plants.

6. Assumptions on the method of operation to be adopted,including such aspects as groundwater mixing andreservoir operation.

The essence of the IACA programme is contained in items 1 and 6 whilethe associated irrigation demands forms ibem L. Item 5 is derived fromthe Stone and Webster report.

The analysis starts at a fixed point in time, which for thisstudy was October 1965, regarded as the beginning of water year 1966.The analysis proceeds to meet the irrigation demands of the basin bythe distribution of surface and groundwater governed by a complex systemof rules, which incorporate all the physical constraints of the systemand all the operating criteria. Similarly the power demand is derivedand supplied by the generating system. Thus the analysis willcalculate the total deliveries of water and power, revealing at the sametime any shortages that may arise.

Three main studies were made of the system in which the only itemsof data that were varied were the monthly river flows. The first studyused for every year the 4l year mean flows of the Indus, Jhelum andChenab which had previously served as the benchmark for the IACA studies.Two further studies were made with historic sequences of river flow;and a variation on one of these studies used critical river flows atselected points in time.

CONCLUSIONS

The principal conclusion arising from this study is that theIACA programme behaved satisfactorily and it confirms the earlier studiesmade by IACA for certain reference years. Some irrigation shortageswere noted but this was expected. The aggregated shortage was 8.2 MAFin the mean year sequence out of a total watercourse delivery over thetwenty years of 1840 I4AF. These shortages occur primarily in twoperiods of time, I.3 MAF in the first two years of the study, which isdue to the very low estimate that was made for the availability of waterfrom the Ravi and Sutlej in the transition period before the advent ofMangla and 2.9 UAF in the three years just prior to the commissioning ofTarbela as demand rises in anticipation of the reservoir. There wereno irrigation shortages beyond 1975 under mean year flows. The historicsequences revealed higher shortages throughout, but as much the sameperiods of time. Excluding the effect of the first two years, which maybe slightly unreal, the aggregated October to May shortages in the twohistoric sequences were 10.1 IMAF and 11.9 WA.F. Kharif shortages alsoarose in the historic sequences, but these were mostly due to exceptionalcircumstances. The IACA programme was not intended to meet requirementsunder all conditions of low river flow and small shortages were there-fore expected. In general these shortages were not more than about6 per cent of the projected watercourse requirement in any year before1975 and less than one per cent thereafter. It is reasonable to concludethat, subject to the limitations of the accuracy of the basic assumptions,the IACA programme contains adequate facilities to meet the projectedirrigation demands.

Since the sequential analyses are operational rather than analyt-ical it is not suitable for an evaluation of the IACA projections forstored water demand. It is however possible to make deductions on thissubject from the incidence of shortages and surpluses and fron thebehaviour of the watertable. Prior to 1975 there is evidence ofirrigation shortages in the system and a small overdraft on the aquifer,restricted to areas of public tubewell development. This is temporarilyrelieved by the installation of the Tarbela reservoir, but by 1980 theoverdraft is becoming more rapid which is an indication that Tarbelastorage water is being fully absorbed and that the system is becomingshort of water again. At this point also the surplus passed to the seain the release period has become very small. By 1985 the total over-draft on the system has reached 8 N4AF in the mean year sequence and 16HAF and 18 MAF in the historic sequences. The higher figures for theh-istoric sequences are due to two factors. Firstly the total rabiflows in the historic sequences are slightly lower than mean, andsecondly the constraint imposed by canal capacities means that the over-draft on the aquifer cannot always be fully replaced by additional surfacewater at times of high river flow.

The two main conclusions from the power aspects of the studyare:

1. There are small deficiencies in peaking capability in theNorth prior to commissioning of the Mangla units, but beyond this point

and with the completion of the North-South inter-tie in 1973 the systempeaking capability exceeds the system demand at all times. After thefirst Tarbela units are commissioned there is also considerable transferof power from North to South.

2. The pumping loads that were calculated in the analysis wereclosely in line with the estimates made by IACA in july 1966, but lessthan those assumed for the Stone and Webster report. This resulted ina higher value arising for the peak power reserve of the system.

Nothing arose from the study to suggest any radical change inthe mode of reservoir operation visualized by IACA, except that itwould seem desirable to draw down Mangla to the lower elevation of 100hwhen required, rather than maintain it at 1075 as previously assumed.

The method of sequential analysis is a valuable technique forexamining alternative development plans and providing a basis forplanning decisions. This study has provided a very useful overallimpression of the irrigation and power programmes in operation. Itwould however be unwise to attach too much emphasis on individualfigures derived from this series of studies for it must be recognizedthat any particular topic will in most cases require more detailedanalysis, on a shorter time base, than is possible in this form of study.

kWATER DISTRIBUTION DEMvxOPMENT PROGRAMME

1. OBJECTIVE

The objective is to carry out a behaviour trial of IACA'sassumed plan for distributing surface water and for the pumping ofgroundwater, simulating the twenty-year period 1965 to 1985, using thecomputer programme developed by Harza operated by an IBM 7094 computer.The programme will be modified as necessary to test the Bank's Con-sultants proposed development plan for water and power and new inputwill be prepared to suit their assumptions.

2. SCOPE

A historic sequence, random or other selection of river flows,will be adopted to include in the twenty year period some years of highflow and some of low level, but the mean of the twenty year period willbe close to the long term mean flow. A separate run will use the meanflow for each year.

Releases from the reservoirs (Mangla and Tarbela) and theoperation of pumps should follow rules which could, in practice, beadopted. Distribution of water will meet the water course requirementsderived from IACA's assumptions regarding crop intensities, patterns andwater requirements. The use of groundwater will follow the assumptionsmade by IACA regarding recharge, mixing ratios and aquifer coefficients.

The analysis will indicate the fluctuation of the groundwaterstorage and levels year by year, the electrical power and energy requiredfor pumping and the capability of, and energy generated at, the hydro-electric power stations at Mangla and Tarbela and water shortages incritical years, following the sequence of IACA's development plan. Theanalysis will also test the Dank's Consultants' power programme againstthe system electrical demand.

3. PROGRAMME AND REPORTS

It is intended that the task will be started on July 3, 1966,and be completed by September 15, 1966.

An interim analysis will be submitted to the Bank and WAPDA onAugust 1, 1966 which will assess the feasibility of completing the taskin the proposed period of 2½ months and which will suggest any changesthat may be necessary in the scope of the analysis as a result of thefirst month's work. Preliminary results will be issued from time totime, when available.

A final report will be issued to the Bank and to WAPDA on com-pletion of the task.

CHAPTER 1

INTRODUCTION

1.1 BACKGROUND TO STUDY

This report is an account of a series of sequential operationstudies of the water and power system of West Pakistan performed inaccordance with the Terms of Reference, reproduced at the front of thisreport. The objective of the studies was to carry out a behaviourtrial of IACA's assumed plan for distributing surface water and for thepumping of groundwater, simulating the twenty year period 1965 to 1985,using the computer programme developed by Harza. The scope of thestudies was also intended by the Terms of Reference to test the WorldBank's Consultants' power programme against the system electricaldemand.

Gibb, in association with the other Bank Consultants, made systemanalyses for certain reference years, including 1975 and 1985, as partof the Indus Special Study. Various potential forms of development ofwater and power resources were tested in the reference years underdifferent conditions of river flows. These system analyses were usedby IACA in conjunction with other studies in order to formulate theproposed programme for development of irrigation supplies described inChapter 2. The IACA porjections for growth of storage demand were usedby C.T. Main in their study of dam sites and the projections for tubewellpumping and hydro energy generation were used by Stone and Webster intheir study of power resources.

The sequential method of analysis evolved by Harza as generalconsultants to WAPDA enables a development programme to be tested forany desired period of consecutive years. The methods of analysis andbasic data used by Gibb and Harza were compared in some detail atmeetings in London and Arnhem in February 1966 and it was found that theexchange of data between the consultants since the inception of theIndus Special Study had resulted in agreement on many of the basic para-meters relating to system analysis. Subsequent to these meetings theBank and WAPDA agreed on the desirability of initiating a series ofstudies combining the development programme of the Bank's consultantsand the techniques of system analysis developed by WAPDA's general con-sultants.

The studies reported herein are the result of a co-operativeeffort between Gibb and Harza. Gibb held primary responsibility forpreparing input data consistent with the Bank consultants' developmentprogramme and the associated technical criteria and assumptions, forselecting the sequences of river flows adopted, and for evaluating theresults. Harza provided advice and assistance in arranging and pro-cessing the input data in the form required for the analysis, and inthe use of computer facilities.

The period July to August 1966 was used for the preparation ofthe input data described in Chapter 4. 'The studies were then carriedout in Chicago in August, 1966, using the IBM 7091 computer at theIllinois Institute of Technology Research Institute.

1.2 CONDITIONS OF SEQUENTIAL RIVER FLOWS

Three analyses and one supplementary analysis were made underdifferent sequences of flow in the Indus, Jhelum and Chenab Rivers.Water years, assumed to begin in October, were used rather than calendaryears. Thus a water year begins in October of the previous calendaryear and continues until September of its own calendar year. In eachcase the analysis was applied to projections for the 20 year sequence ofwater years from 1966 to 1985.

The four conditions of sequential river flors were:-

(i) Mean Year Sequence

A mean water year was used in each of the 20 years forthis analysis. The mean was taken from monthly flowsover the same 41 year period of water years, 1923 to1963, as were adopted in the IACA studies. This sequenceprovided a direct comparison with many of the IACA pro-jections.

(ii) First Historic Sequence

For this sequence actual recorded river flows were used.The historic period of water years 1926 to 1945 wasapplied in the same sequence to the period of the study1966 to 1985. In this way the programme was tested undera sequence of river flows which were known to have actuallyoccurred.

(iii) Second Historic Sequence

This analysis provided a second test of the programmeunder actual river flows. The same period of water yearswas used as in the previous analysis but the order of thesequence was transposed by ten years. The historic flowsof the water years 1926 to 1935 were applied to the period1976 to -1985 and the years 1936 to 1945 were applied to1966 to 1975.

(iv) Supplementary Sequence

The -river flows in this analysis were the same as in thefirst historic sequence except that certain flows werereplaced by those of a critically low water year. Thisanalysis served as a further test cn the power programmeand as a check on the possible scale of irrigation.

shortages. The critical water year selected was 1955which was also used in the IACA studies. In this wateryear the lowest October to May floir of record occurredon the Indus, Jhelum and Chenab Rivers combined. Thiscritical year was applied to 1976 ;nd 1985. It wasnot used for the water year 197L, which is likely to bedifficult for power, as both the h:.storic sequenceshappened to produce low rabi flows for that year.

The conditions of sequential river flows are discussed in moredetail with the assumptions for other tributary rivrer flowis in Section.l4. The other input data described in Chapter b wrere the same in

each of the sequential analyses.

CHAPTER 2

THE DEVELOPMENT PROGRAMME

LICA considered potential development of water resources in theIndus Basin from the combined aspects of agriculturo, water supply andeconomics. These considerations led to a proposed groundwater andcanal development programme which is reproduced as F'igure 1 of thisreport. The installed tubewell capacities, canal sizes and irrigationrequirements which are used as input data for the soquential analyseswere based on this programme for development.

The dominant feature during the first decade of the IACA pro-gramme is the continued installation of tubewells to provide newirrigation supplies and simultaneously to control the watertable. Thefollowing decade from 1975 to 1985 would witness tho extension ofpublic tubewells fields over the outstanding usable groundwater areasand hence the achievement of fully integrated tubewoll and canalsupplies. IACA's estimate for the number of public and private tube-wells which would be operating in reference years fr'om 1965 to 1985under their proposed programme is shown in Table 2.1.

TABLE 2.1

Projected Number of Wells in Operation

Plan Year 1965 1970 1975 1980 1985

Public Wells(2 to 5 cuseccapacity)

Usable groundwater 2,200 9,500 19,800 32,200 34,300Saline groundwater - - 200 I,500 9,800

Private Wells(Approx. 1 cuseccapacity. Canalcommanded anduncommanded areas)

The scheduled completion of Mangla Dam (4.5 MAF) on the JhelumRiver in 1967 has a predetermined place in the IACA programme as alsodoes the proposed Tarbela Dam (8.6 MAF) which, undee the IACA terms ofreference, is assumed to begin operation on the Indus River in theautumn of 1974. Surface storage development is alsc expected atChasma in 1971 but the reservoir size there would be relatively small(0.5 MAF). Further storage proposed by IACA at Sehuran/Manchar

(2.2 MAF capacity), equivalent to 1.8 MAF of useful storage, in 1982would be particularly related to the enlargement and remodelling ofRohri Canal. Other storage projects would be implemented after 1985which is the last reference year for the sequential analysis.

The improved irrigation supplies and the control over the water-table in usable groundwater zones form the backgrouad to canal enlarge-ment in the IACA programme. Canal enlargement is a:plied to a limitednumber of canal commands in the first decade but the programme for en-largement gains momentum and takes the leading rule in further develop-ment. IACA's projections for the areas which would be developed bycanal enlargement-and by tubewells and horizontal d&ains are shown inTable 2.2 for 1965, 1975 and 1985.

CHAPTER 3

I4ETHOD OF ANALYSIS

3.1 GENERAL

The method of analysis consists of a numerical model of theIndus Basin Power and Irrigation System which simulates system operationusing time intervals of one month for any desired period of years. Thesystem corresponds geographically to the Indus Plains and the PeshawarVale and the storage reservoirs on the Indus and its principal tribu-taries. The basic model includes all existing irrigation and powerfacilities, projects under construction and all major potential projectsas shown in Figure 2. Individual components of the system may beincluded, excluded, or modified by suitable selections of input data.The water and power demands of the system are also defined by input datawhich can be chosen to correspond to projected future demands. An IBM7094 electronic computer is used to perform the computations. Thecomputer programme and the general principles of system operationassumed in its formulation, are described in 'A Guide to the ComputerProgram' published by Harza in March 1966 and revised in September 1966.

The account of the method of analysis contained in this sectionis largely confined to a discussion of those areas where the proceduresfollowed in the Harza method differ fram the procedures and assumptionsadopted in the system analyses made by IACA in the course of the IndusSpecial Study. Reference should be made to 'A Guide to the ComputerProgram' for a more detailed account of the Harza method of analysis.

3.2 INTEGRATED USE OF SURFACE AND GROUNDWATER

The IACA and Harza system studies differ in regard to the useof groundwater. In the IACA analysis the pattern of groundwater pump-ing is pre-determined by Discrete canal command studies in which allow-ance is made for groundwater mixing and the state of development ofpublic and private tubewells. The remainder of the watercourse require-ment is made up by surface water deliveries. The elements of surfacewater are then aggregated to build the demand throughout the system.The Harza computer programme works in the reverse manner by first dis-tributing surface water throughout the system and then pumping in thecanal commands to meet the watercourse requirements. Both studies aimto balance the volume of recharge in a command by an equal amount ofgroundwater pumping, thus maintaining the groundwater at a fairlyconstant level. In the Harza system analysis pumping may, howeverexceed recharge when surface water deliveries are limited by canalcapacity or by a general shortage of water in the system and IACAassumed the same principle in their development plan.

In practice the two approaches would produce much the same results.

Consequently it was decided to retain the Harza logic in the analysis

without any change to the computer programme.

The Harza and IACA methods of analysis both assume a high degreeof co-ordination between surface water distribution and groundwater use.

Both consultants recognise the difficulty of including privately ownedtubewells in an integrated system. Current indications are thatutilisation factors for private wells are much lower than for publicwells. Preliminary system analyses made by Harza indicated that the

lower utilisation faccors associated with private tubewells could be

recognised in the analysis by means of input data rather than by a

change in the computer programme. The effective pumping capacity for

private wells was taken as 30 per cent of installed capacity and for

public wells as 87 per cent of the installed capacity, which represents

the maximum monthly utilisation rate adopted as a criterion by IACA.

This subject is elaborated in Chapter 4.

3.3 POIER AND ENERGY GENERATION

Although the Stone and liebster basic load projections and plant

installation schedule were adopted as input data for the sequential

study, complete compatibility cannot be achieved due to differences

that exist between the Stone and Webster method of computing the peaking

capability at the hydro plants and that of Harza. Stone and Webster

impose a limitation on peaking capability in months when reservoir out-

flow is less than the flow required for continuous full gate operation

of the turbines. Harza do not impose any restriction on peakingcapability other than that resulting from the head on the turbines and

it is assumed that full gate output can be developed whenever required.

However in the months of minimum reserve generating capacity the

reservoir outflows are in most cases sufficiently large to allow full

gate operation and therefore at such times the Stone and Webster method

does not result in any significant reduction in peaking capability.Furthermore the Stone and Webster analysis of generating capability is

based on calculations at ten day intervals and the hydro capability for

any month is governed by the lowest ten day period. In the Harza

analysis hydro peaking capability is determined by the head correspond-ing to the mean reservoir level for the month. In effect the

comparison would be between a minimum capability and an average value.

It was decided to retain the Harza logic in the analysis,

although it was recognised that the peak reserve indicated might be

higher than obtained in the Stone and Webster analysis. The effects

of the two different methods of calculating peak reserves are examinedin Chapter 5.

3.4 LOAD DISPATCHING AND INTER-ZONE TRANSFERS

The basic power and energy demands for the North and South Zones

are defined by input data and groundwater pumping loads are computed

in the analysis. Total power and energy demands are thereforeobtained for each month of each year of the analysis and for each zone.Two important elements of the load duration curve-are then derived,the maximum ordinate, which 9s akb fir thetotal area under

the curve which is the total energy`.lBy assum he curve to beparabolic and to be a function of the system load- factor, it is possibleto define the complete shape of the mont-hly load duration curve, and to

match the requirements with the hydro and thermal components.

A load dispatching process is used in the analysis to determinepeak reserves or deficiences in each zone, and to compute inter-zonetransfGrs of power and energy. For the purposes of the analysis the

South Zone includes Karachi. Transfers between the North and South

Zone can only take place after interconnection, the date of which is

determined by input data (1973 in the analyses described herein).Transfers from South to North take place only when there is a capacity

deficiency in the North and reserve capacity in the South. Transfers

from the North to South will always take place when there is surplus hydro

capacity after the demands of the North Zone have been met, to reduce

the consumption of thermal power in the South Zone.

- 9 -CHAPTER 4

INPUT DATA

4.1 GENERPL

The input data used in the sequential analysis fall into sixmain categories:

(i) data descriptive of the existing and future physical com-ponents of the irrigation system, such as canal commands,main canals, link canals, barrages and reservoirs, andtubewells for irrigation and drainage;

(ii) data relating to groundwater hydrology including seepageloss factors, areal variations in groundwater quality,aquifer storage coefficients, and estimates of rechargefrom rivers, link canals and rainfall;

(iii) the surface water supply to the system expressed asmonthly river flows by years at the rim stations;

(iv) the demand for irrigation water expressed as monthlywatercourse requirements by years for each canal command,based on the development programme selected for analysis;

(v) projected demands for basic power and energy for eachmonth of the study period, the factors used to expressgroundwater pumping in terms of electric power and energy,and the capacities and characteristics of existing andfuture thermal and hydro-electric generating plants;

(vi) system operating criteria such as groundwater mixingratios, reservoir release patterns, and minimum releasesbelow reservoirs and barrages.

For the analyses described in this report, the input data areconsistent with the IACA and Stone and Webster development programmesand the associated assumptions and criteria. Different conditions ofsurface water supply to the system were considered in each of thesequential analyses but other input data remained the same in eachanalysis.

The account of the more significant input data presented in thischapter under the above headings is supplemented by further detailscontained in Appendix A.

4.2 THE IRRIGATION SYSTEM

(a) Comparison of Canal Commands

In their basin studies IACA used 61 divided canal command units,whereas the Harza analysis allows for 45 units covering the same geo-graphical area. It was therefore necessary to combine certain IACAunits, and in some cases to split units in order to make them compatiblewith the computer programme. The configuration of commands that wasfinally adopted corresponds closely to that used in Harza studies exceptthat Abbasia was combined with Panjnad, Desert with Pat, and Pinyariwith Fuleli. Thus 42 canal commands emerge which are shown in Table4.1 with the corresponding IACA commands indicated where the nomencla-ture differs. The IACA canal commands are shown in Figure 3.

(b) Link Canals

The system includes all existing link canals, the link canals ofthe Indus Basin Project, the canals required for diversion of Induswaters to offstream storage reservoirs and the canals associated withthe Sehwan Development.

The link canals of the system and the capacities adopted in theanalysis are tabulated in Appendix A.

The head and tail capacities of the link canals are defined byinput data for each year of the study; capacities are set at zero inthe years prior to commissioning. None of the canals required foroffstream storage set in the Harza programme are included in the IACAprogramme and hence their capacities are zero throughout the study.The links of the Indus Basin Project are introduced in the analysis inaccordance with the current construction programme.

There are three canals in the South Zone considered as linkcanals:

(i) the Nara Feeder, which is the existing canal supplyingthe Nara Command from Sukkur;

(ii) the Sehwan Feeder, which serve Sehwan Command(Rohri South) from Sehwan;

(iii) the Sehwan-Nara Link which will serve the Nara Commandfrom Sehwan.

In the IACA programme the Sehwan Feeder is assumed to commenceoperation in 1982, and Nara Command continues to be served from Sukkurthrough 1985.

(c) Canal capacities

The IACA figures for canal capacity were adopted throughout.At various points in time canal capacities were enlarged in accordancewith the IACA programme. The canal capacities used and the extentand timing of enlargement are shown in Appendix A.

(d) Reservoirs

The study assumes that three major reservoir schemes are intro-duced into the system.

(i) Low Mangla

This has an initial live capacity of L.94 MAF between E1.1202and E1.1040. The useful storage at a drawdown level of 1075,that was used in the IACA studies, is bl.5 MAF. For practicalreasons the volume of water trapped in the Jari arm wasneglected but the effect of this extra water is considered inthe evaluation of results. Impounding commences at Manglain April 1967.

(ii) Tarbela

The initial live storage content is 9.3 MAF between El.1550and El.1300. However the IACA assumption is that drawdownwill only be'-to El.1332, which allows a live capacity of 8.6MAF. Impounding is assumed to start in August 1974 and itwas considered for the purpose of the analysis that this wouldpermit only-5-.0 MAF to be stored in the first year of operation.Full impounding begins in June 1975.

(iii) Sehwan

The Sehwan project is assumed to come into operation inSeptember 1982 with a storage capacity of 2.2 MAF, takenfrom the LIP report, which after evaporation allows auseful storage of about 1.8 MAF.

All three reservoirs are subject to evaporation losses and sedi-mentation. In the case of Mangla and Tarbela evaporation losses aresmall in relation to storage capacity and only amount to an annualvalue of 0.05 and 0.1 YAF respectively during the release period. AtSehwan, however, they are significant and account for about 20 per centof the storage capacity. On the other hand Mangla and Tarbela,particularly the latter, suffer from quite severe sedimentation. Thesediment is treated as a function of river flow and at both thesereservoirs 50 per cent of the sediment is considered as depleting livestorage. The figures used for sedimentation are such that in a meanwater year Mangla depletes at a rate of 0.02 MAF a year and Tarbela at0.12 MAF a year.

No allowance is made in the study for the Chasma reservoir whichwould store up to 0.5 MAO since it was considered that it would be bestoperated on a variable release pattern, and the computer programme allowsvariable operation only at the main reservoirs. However allowancecan be made for this in considering the results.

(e) Tubewell Installation

The pattern of tubewell installation is based on the IACAprojections for public and private tubewell development. Tubewellcapacity is in two parts, tubewells used for irrigation and in somecases also for drainage in the areas of usable groundwater and tube-wells used for drainage alone in the areas of saline grcundwater.

In the areas of usable groundwater the tubewell capacity wascalculated for every command for each of the twenty years of the study.For public tubewell areas the effective capacities used are 87 per centof the existing, or planned, installed capacities, since 87 per centrepresents the peak monthly utilisation factor projected by IACA. Inthe case of private tubewells a different approach was used. The IACAprojections have assumed an annual utilisation factor for private wellsof 27.4 per cent. The difficulty that arises is that the logic of thecomputer programme will try to maintain the groundwater table at afixed level, in this case, ten feet. This has the effect that in anarea of low installed tubewell capacity, the pumps will be used to100 per cent of their capacity, which will give unrealistic quantitiesof groundwater pumping. To offset this tendency the value of effectivecapacity for private tubewells was tacen as thirty per cent of the in-stalled capacity. This will correct the annual pumping total thoughat the same time leaving no flexibility in the monthly figure. In areasof mixed development (i.e. private and public wells in the same command)

- 14 -

the capacities of public and private tubewells were added. Someallowance was also made for persian wheels in the early years of thestudy. The use of groundwhater in a command is physically limited bythe capacities as computed above, but, mixing criteria also imposelimitations and these are discussed in section 4.7(a). A table showingthe installed capacity for each command at four points in time, 1970,1975, 1980 and 1985 is shown in Appendix A.

Drainage capacity in the saline areas was installed in accordancewith the IACA plan. Three options exist for the disposal of drainagewater.

(i) To discharge it into the river.

(ii) To evaporate it in salt-pans.

(iii) To pass it by drains into the sea.

Also, in some commands drainage pumping and release of drainageto the rivers is restricted to months of high river flow in order toensure dilution of drainage effluent. The assumptions regarding thetiming and disposal of drainage releases for each of the canal commandsare set forth in Appendix A.

1.3 GROUNDW1ATER HYDROLOGY

(a) Quality of Groundwater

In order that watertable depths and drainage requirements canbe estimated, each canal command is divided into 'area good' and 'areabad'. 'Area good' is the area wherein mixing criteria allows all re-charge to be pumped for irrigation use and is defined as the part ofthe gross commanded area lying outside the 3000 ppm isogram or the 2000ppm isogram in the case of the Lower Indus canal commands. 'Area bad'is the area wherein none of the recharge can be used for irrigation,and is the part of the gross commanded area lying within the 3000 ppmisogram or 2000 ppm for Lower Indus. The use of groundwater qualitydata in the determination of mixing ratios is explained in Section 4.7(a).

(b) Aquifer Storage Coefficient

The aquifer storage coefficients used in the study are 0.15 forthe North Zone and 0.13 for the South Zone. This means, for examplein the South Zone, that one cubic foot of aquifer below the watertablecontains 0.13 cubic feet of recoverable groundwater. The change indepth to groundwater (an average value for each canal command) is asimple computation based on aquifer storage coefficient, 'area good' or'area bad', and the difference between pumping and recharge. Estimatesof depth to groundwater are therefore directly related to the aquiferstorage coefficient.

- 15 -

(c) Canal Loss Factors

Loss factors used to compute seepage and evapotranspirationlosses from the main canal systems and the link canals are those used byIACA in their system analysis. The annual computed losses as a percent-age of annual canal head diversions are about 28 per cent in the NorthZone, and 23 per cent in the South Zone. Annual link canal losses rangefrom 5.2 MAF to 6.1 MAF.

The proportion of main canal losses going to groundwater re-charge is defined by input data; in this analysis a value of 0.80 wasused.

(d) Watercourse Field Losses

The losses assumed in the analysis are as follows:

Watercourse loss 10% of watercourse deliveryField losses 30r of field delivery

IACA assume that one half of the watercourse loss and one thirdof the field loss are non-recoverable. Therefore the recoverable loss,or recharge, is 23 per cent of the watercourse delivery and this value isused for all canal commands in the system.

(e) River Losses and Gains

The factors and equations used to compute river losses and gainsare tabulated .in Appendix A. The factors were derived by Harza fromflow records for the period 1937 - 1946 and were also used in the IACAstudies.

(f) Groundwater Recharge

The three main components of groundwater recharge are:

(i) Seepage from main canal systems (all channels in acanal command between the head of the main canal andthe head-'of the watercourse).

(ii) Seepage-_from watercourses and deep percolation fromthe f ields.

(iii) Other 1os686 to groundwater which include seepagefrom-li•k-canals and rivers, and rain throughput.

Components~(i) and (ii) are directly computed in the analysis.The factors required for the computation are introduced as input data.

Component (iii) is input data and values of this component foreach month and for each canal command are computed by hand. Previous

- 16 -

studies are used to obtain total link canal and river losses. Riverlosses in each river reach were divided into the seepage and evapo-transpiration components and the recharge from each reach computed anda similar calculation was made for link canals. The annual contributionof links and rivers to recharge within the canal cammands is of the orderof 9 MAP. This is less than 'total seepage losses since some lossesoccur outside the canal commands. The distribution of the link andriver recharge between the commands is based on map studies, and rainthroughput is added to obtain monthly values of component (iii) for eachcanal command.

The computer programme is so written that the computed values forcomponents (i) and (ii) for each month in each command are added to inputvalues for component (iii) to obtain total recharge. The total rechargeis then multiplied by a factor (defined in the input data) to obtain thedistribution of recharge between 'area good' and 'area bad'; values forthis factor are obtained by map studies and hand computations based onprevious system analyses.

L .L SURFACE WIATER SUPPLIES

(a) Indus, Jhelum and Chenab Supplies

The conditions of sequential river flows used in the analysishave been described in Section 2.2. In the historic sequence, theactual river flows have a considerable bearing on the results of theanalysis. Months of high river flow can produce plentiful surfacewater supplies and a reduction of groundwater use, whereas low flowscan increase the tubewell pumping requirements and cause shortages. Themean water year used by IACA may be regarded as a bencbmark and an exam-ination of variations in the historic sequence from the mean provides avaluable guiding light in which to view the results.

Table h.2 shows how the rabi flows from October to March for thehistoric sequences vary from the 41 year mean flows used by IACA. Themost striking feature is that on total balance for the twenty yearperiod the rabi flows between October and March in the Jhelum and ChenabRivers combined are 17 WAP less than mean. The Chenab has a particu-larly large number of low flow years with a total of 12 MAF less thanmean in rabi over the twenty year period. The Indus rabi flows areslightly higher than mean on balance over the twenty years.

The overall effect of the variations in the historic sequencesfrom the mean water years would be to produce rather critical conditionsof surface water availability in the areas served by the Jhelum andChenab Rivers alone, shown in Figure 4. These critical conditionswould in turn be reflected in the remainder of the system in spite ofthe fact that Indus flows in total are reasonably close to the mean.One factor which influenced the choice of years was that Harza hadalready processed figures for river flows in a thirteen year sequenceand considerable extra work was avoided by incorporating this thirteen

year Harza period into the twenty year period for the sequentialanalysis. It was also considered that a more trenchant test of theIACA programme would be provided by low rabi flows than by high flows.

Apart froma these overall considerations of the twenty year period,there are significant variations in individual years and months. Thelowest combined rabi flow was in 1941, equivalent to 1981 in the firsthistoric sequence and to 1971 in the second historic sequence, when thetotal flow was 7.0 MAF less than the mean. On the other hand in 1930,equivalent to 1970 and 1980 in the first and second sequences respect-ively, the total flow was 8.3 MAF higher than the mean. The fullmonthly flows for the three rivers are shown in Appendix A.

For input into the computer programme, flows of the Indus Riverat Attock are divided into the component flows of the Kabul River atIJarsak, the Swat River at Amandara and the Indus at Tarbela. The Indus atTarbela is itself composed of the Indus at Darband plus the Siran River, asmall tributary between Darband and Tarbela, Indus flows at Darband werebased on Attock records and were derived from the method agreed in 1964 byGibb, Harza and TAMS and described in Annexure 4 of the IACA Comprehensive

Report. Studies were made by Harza in 1964 to derive data for the Swatand Kabul Rivers which when combined with the Tarbela flows would beconsistent with the Attock record. The study revealed an annual discrepancy ofof about 4 MAF which was removed by the introduction of a tributaryinflow to the Kabul below Warsak. Tributary inflow on the Swat Riverbelow Amandara represents supplies from the Panjkora River, a majortributary of the Swat.

A further tributary inflow was introduced on the Jhelum River inorder to take account of the recorded gains in the river between Manglaand Rasul.

(b) Ravi and Su.tlej Supplies

Surface water supplies from the Ravi and Sutlej Rivers weretreated differently from those of the Indus, Jhelum and Chenab. Underthe terms of the Indus Water Treaty the flows of the Ravi and Sutlejwill be available for use wholly by India after 31st March, 1970, unlessPakistan applies for a deferment of up to three years. The proceduresfor sharing supplies in the Ravi and Sutlej during the transition periodbefore 31st March, 1970, are set out in Annexure H of the Indus WatersTreaty. In January 1966 Harza made a study (unpublished) in order todetermine haf much water could actually be expected by Pakistan fromthese rivers during the transition period. Harza based their calcula-tions on discharges in the water year 1945 which they considered tocorrespond approximately to average year runoff conditions for the Raviand Sutlej. They then computed the minimum supplies which would haveto be released by India to fulfill her obligations under the Treaty.Supplies were considered in two periocb; the first period extended to30th September, 1968, after which it was assumed that Mangla releaseswould be fully available for use in Pakistan, and the second period wasfrom 1st October, 1968, to the end of the transition on 31st March 1970.It was calculated that in the second period, starting on 1st October,1968, there would be no rabi water supplies available from India.During the first period, up to the 30th September, 1968, there would besupplies from the Sutlej River at Ferozepore and from the Ravi River atMadhopur through the Upper Bari Doab Canal. The total rabi flowsentering Pakistan between October and March in the water years 1967 and1968 would be:

Ravi River to Central Bari Doab Canal 0.48 MAFSutlej River at Ferozepore 1.80 IAF

Total 2.28 MAF

The supplies computed by Harza for the Ravi and Sutlej Riverswere used in each of the sequential analyses and are tabulated inAppendix A. The rabi supplies computed by Harza are substantially lessthan either the assumed replacement storage at Mangla of 4.75 MAF or thehistoric deliveries from the Ravi and Sutlej. The effect on theanalysis of these low rabi supplies is to produce shortages which may ormay not occur in-practice during the years before the advent of XMangla,

a period which is well before the IACA projections become effective.

4.5 WATERCOURSE REQUIREMENTS

Irrigation water requirements at the watercourse are functions ofthe development programme and are the primary determinants of the scopeand timing of other physical works such as storage reservoirs, enlarge-ment of main canals and link canals, tubewell capacities and the gener-ating facilities needed to serve the pumping loads. Monthly watercourserequirements for each canal command for each year of study constitutethe most important block of input data. The watercourse requirementsaccount for 10,000 separate values out of about 60,000 separate valuesfor all kinds of input data in each sequential analysis.

As part of their planning studies IACA computed watercourserequirements for the reference years 1970, 1975 and 1985 and estimateswere also made for present conditions of development. For the years1975 and 1985 the requirements were based on full crop watering for theprojected cropping patterns and intensities. In the period prior to1975 the transition from present day watercourse deliveries with itsassociated underwatering and unregulated deliveries to optimal deliverieswas accomplished in three ways.

(i) In commands where public tubewells are installed,full delta watercourse requirements coincide withthe implementation of the project.

(ii) In the remaining commands, supplied by the Jhelumand Chenab rivers, Mangla reservoir is assumed to becapable of regulating rabi flows. In these areashistoric seasonal totals were maintained but re-distributed by months in accordance with the computedrequirements.

(iii) In commands served by the Indus main stem in which nopublic tubewell development was scheduled before 1975mean historic monthly deliveries were maintainedwithout regulation.

In conditions (ii) and (iii) an extra allowance was made for thecontribution of private pumping.

These figures were derived for the 61 development units of theIACA study and therefore had to be rearranged to suit the 42 canalcommands used in the analysis. Finally it was necessary to inter-polate between the reference years to obtain watercourse requirementsfor the remaining years of the study period. Interpolation factorswere used which were keyed to the IACA projections for growth ofintensities. A programme was developed for an IBM 1620 computer andused to compute the monthly values and punch the cards in the formatrequired for the IBM 709M. Such an approach necessarily involves a

- 20 -

certain degree of approximation and the validity of the figures shouldonly be viewed on an overall basis. Figures for the annual total ofwatercourse requirement in certain reference years in each command withthe appropriate intensity are given in Appendix A.

1!.6 POIWER DEMANDS AND INSTALLATION

The forecasts of basic power and energy demands prepared by Stoneand Webster were used as input data in the sequential analysis. Thebasic load includes all classes of load other than pumping loads forirrigation and drainage. Pumping loads are computed in the analysis byapplying factors to the monthly volumes of groundwater pumping and thenadded to the basic loads to obtain energy and power demands for thesystem.

The thermal plants and hydro-electric generating units wereintroduced during the study period in accordance with the Stone andWebster schedule reproduced in Appendix A. The boundary of the NorthZone is south of the Multan thermal plant. The South Zone includesKarachi for the purpose of this analysis. The capacity of the North-South inter-tie is defined by input data, and a capacity in excess ofpotential transfers was used in the study in order to determine themaximum extent to which the output of the North Zone hydro plant couldbe used in the South.

h.7 OPERATING CRITERIA

(a) Mixing Ratios

In the IACA studies groundwater quality zones were treated asseparate entities and the following mixing ratios were adopted.*

Deep Groundwater Average Mixing RatioQuality Zone Surface Wvfater to

(ppm TDS) Groundwater

0 - 1000 No restriction1000 - 2000 1 : 12000 - 3000 2½ : 1

Over 3000* No groundwater use

*Although the computer study does not deal with groundwater zonesexplicitly the mixing ratio is controlled in the programme by a factor whichonly permits a prQportion of the watercourse delivery to be met by ground-water. This factor will vary from 1.0 in a fresh groundwater zone to zeroin a saline zone, and for a command with different zones a weighted averagefactor was calculated. These calculations were made separately for eachcommand over the twenty years and account for the apparent monthly variationof pumping capacity.This factor was also used to control the internal distribution of ground-water within a canal command and prevent pumps from supplying the watercourserequirements of an area not served by tubewells. This is particularlyimportant in the case of private tubewells which are concentrated inportions of the canal command and cannot supply the remainder of that command.

**Over 2000 ppm in Lower Indus commands.

(b) Reservoir Operation

The reservoirs were operated in the manner suggested in the IACAReport with the following fixed release patterns, shown below as amonthly percentage of live storage.

The releases at Tarbela were slightly modified in 1975 sinceonly 5 ItAF was impounded in the previous year. The release patternswere developed to make allowance for an average condition of low rabi,but would clearly be modified in operation to match the variation inriver flows. It was however, considered too complicated to vary therelease patterns in the study, and hence they remained constant.

After an examination of preliminary results it was concludedthat there was no justification in maintaining the drawdown level atMangla as high as 1075. Consequently the reservoir was drawn down to1040 in all years except 1975 when there appeared to be a slight shortageof power capability.

The following outlet facilities were assumed to be effective:

Mangla below Spillway crest (1086) 4 tunnelsTarbela below Spillway crest (1492) 4 tunnelsSehwan No restriction

Outlet capacities below the spillway level at Mangla and Tarbelaare governed by the installation of turbines and valves. Above thespillway crest the capacity is virtually unrestricted.

(c) Link Canals

The computer programme provides for several alternative modesof operation for the Chasma-Jhelum and Taunsa-Panjnad Links. In thisanalysis the Chasma-Jhelum Link is operated to meet requirements at Trimmu,and the Taunsa-Panjnad Link is operated to meet requirements at Panjnad,when Jhelum and Chenab flows are not sufficient to meet the demands atthese diversion points.

*Due to an input error, a small amount of impounding takes place atINangla in April. In fact this makes no significant difference tothe analysis as in a mean year 0.3 MAF is in any case involuntaryimpounded due to the restriction of the outlet capacity.

CHAPTER 5

PRINCIPAL RESULTS OF ANALYSIS

5.1 GENERAL

The results of the sequential analysis for the period 1966-1985generally confirm the earlier studies made by IACA for certain referenceyears including 1975 and 1985. The water and power demands of thesystem as projected by IACA and Stone and Webster are adequately servedby the physical works embodied in their development programmes.

As discussed elsewhere in this chapter, the sequential anlaysisrevealed some irrigation shortages in the early years of development,and also in some months of critically low water years prior to thecommissioning of Tarbela. The former shortages occur before the IACAprojections become effective, and the latter shortages are reflectionsof the underwatering assumed by IACA in the pre-Tarbela period.

The minimum reserve generating capacity of the system is higherin most years than indicated in the Stone and Webster report due to thelower pumping loads derived in the study* A study to determinewhether these findings would justify modifications in the power develop-ment would be beyond the scope of this report.

The method of sequential analysis is a valuable technique forexamining alternative development plans and for providing a basis forplanning decisions. It would however, be unwise to attach too muchemphasis to the figures derived in this study. It should be recognizedthat any particular topic will in most cases require more detailedanalysis than is possible in this form of study. Studies using a timebase shorter than one month would be required when considering thedesign or operation of individual projects. This comment applies tofeatures such as reservoir release patterns, outlet capacity require-ments, and integrated operation of the thermal and hydro plants, wherethe results of a sequential analysis should be supplemented by dailyor weekly operation studies.

Four copies of the complete series of computer output for thisstudy were produced. One copy was submitted to the Bank, one sent toWAPDA, and one each retained by Gibb in London and Harza in Chicago.However, summaries of the most important parts of the output have beenreproduced as Appendices B to C of this report. The system summarysheets for the mean-year sequence together with the breakdown summariesfor the North and South zones are contained in Appendix B. The systemsummary alone for the first historic sequence is presented in Appendix C.

* The pumping loads derived are in line with the latest projectionsof IACA made in July 1966.

Table 5.1 presents a summary of the watercourse requirements forthe next two decades and shows the breakdown of deliveries in terms ofsurface and groundwater, under mean year conditions. The volume ofgroundwater pumped is slightly higher than projected in the IACA reportfor the reference years. The subject of groundwater pumping is con-sidered in Section 5.2(c).

(b) Shortages and Surplus

The crucial test of the IACA programme as analysed in this studyis the extent to which the planned installation of groundwater andsurface water facilities can meet the demands of the projected agri-cultural growth. Any deficiency would appear as a shortage at thewatercourse. The pattern of shortages that arise under mean yearconditions is shown in Table 5.2.

No shortages were revealed in the analysis beyond 1975, at whichpoint there is ample surface storage available and the tubewell pro-gramme is well advanced. This result in itself is not very significant,since the programe is geared to meet water requirements in conditionslower than mean. Any deficiencies would have been surprising and anindication of incorrect projections. The output of Appendix B doesshow occasional small shortages in Kharif, which are the result ofapproximations in the method of calculation and should be ignored. Thetotal shortage prior to 1975 is 8.2 MA and occurs primarily in twoperiods, the first two years of the study, and the period from 1972 to19714 just before Tarbela comes into operation. The combined shortageof 1.3 IAF in 1966 and 1967 arises from the restricted allowance thathas been made for the flows of the Ravi and Sutlej Rivers in the trans-ition period before the advent of Mangla storage. The early years ofthe study are based on present deliveries, and do not form part of theIACA plan. Hence such shortages are not very meaningful and inpractice would depend entirely on the actual flows passed down theSutlej and Ravi. The impact of Mangla reservoir in the water year 1968is evident, and this factor in conjunction with increasing tubewellcapacity reduces shortages to a low level until 1973. At this pointthe demand is rising in anticipation of Tarbela storage. The shortageswe equivalent to about 3 per cent of deliveries from October to April in1973, rising to 3¼2 per cent in 19714. These small shortages are theresult of interpolation in the input data and would be reflected in theundertatering projected by IACA before Tarbela.

A measure of t&e efficiency of the use of water is the extentto which surface water, s passed to the sea during the period ofreservoir release. Tjhe surplus at Ghulam Mohammed is shown in Table5.3. A certain qua4tity of water is passed to the sea in October, amonth during which '-substantial releases are made at Mangla. All theMangla releases however are effectively used upstream of Trimmu and thesurplus at Ghulam Mohammed is entirely due to flows from the Indus. In1976 some water is surplus during the release period, but by 1982 thishas shrunk to inconsiderable proportions.

A study of the shortages that occur under the historic sequencesof river flow is a more revealing test of the programme than under themean year sequence. These figures are shown in Tables 5.4 and 5.6 withthe corresponding surpluses in Tables 5.5 and 5.7. As would be expectedthe shortages are somewhat larger than under mean year flows. Againneglecting the first two years of the study, the first historic sequencereveals October to Nay shortages from 1968-1974 totalling 7.3 MAF.This is an average shortage of about 3¼ per cent of the rabi watercourserequirement during the period, with the highest shortage of 6½ per centoccurring in 197M. From 1975 - 1985 the total shortage is 2.8 MAF.Of this figure, however, 2.2 MAF occurs in the month of October, whichis a special case. These shortages occur in those areas which are onlycommanded by Mangla. The watercourse requirements in these commandsare at a high peak in October and there is little spare capacity in the

- 26 -

tubewells to supplement shortfalls in the river flows. The problem isaccentuated by the selection of a historic sequence of flows thatcontains rather low rabi flows for the Chenab and Jhelum. The Octoberto March mean for the twenty years is about 0.85 MAAF below the 41 yearmean (See Section I1.4). Thus the system has been tested under some-what severe circumstances. The shortages in low water years could bealleviated to some extent by modifying the releases at Mangla forOctober, as suggested by the IACA report.

Apart from the October shortage there is a total of 0.6 MAFoccurring at random during the rabi months over the entire ten yearperiod from 1975 to 1985. This represents less than half a per cent ofthe watercourse requirement and may be regarded as negligible. In anycase the capacity of the Chasma reservoir would be more than adequateto overcome these shortages.

The pattern of shortages in the second historic sequence bearsa marked resemblance to that of the first historic sequence. From1968 to 19714 there is a total October to May shortage of 9 MAF, theworst amnual total reaching 2.5 MAF in 1971. From 1975 onwards theshortage is 2.9 MAF of which the largest proportion, 1.7 MAF occurs inthe month of October for similar reasons as before. Of the remainingshortages part arises in 1975, when the full benefit of Tarbela is notavailable, and part is due to an exceptionally low May in 1984.

In both historic sequences occasional shortages are apparent inJune, and there are also September shortages in the Jhelum and Chenabcommands in the early years of the second historic sequence before thecompletion of the T-P Link. The effect of a low June would be offsetby a reduction in the reservoir impounding for that month.

Finally an examination of the critical years in 1976 and 1985reveals no significantly large shortages. The conclusion that can bedrawn from these results is that subject to the limitations of theaccuracy of the basic assumptions the IACA programme contains adequatefacilities to meet the irrigation demands. The IACA programme was notintended to meet requirements under all conditions that might arise andsmall shortages were therefore expected in some months of the historicsequences. Such shortages as exist are confined almost entirely to theperiod prior to 1975, or more pertinently the commissioning of Tarbela,and even these shortages are put in perspective when compared to thetotal projected watercourse deliveries over the twenty years of 1840MAF.

(c) Control of the Watertable

The IACA programme emphasises the intensive installation oftubewells in areas underlain by usable groundwater. Both public andprivate development are important to this programme in the early yearsbut by 1980 most of the usable groundwater in the canal commanded areaswould be covered by the public tubewell projects. These projectswould then be extended at a declining rate into the few remaining canalcommanded areas with usable groundwater during the decade after 1980.Also by about 1980 the early public tubewells would be operating atabout their maximum average utilisations. The general pattern of pump-ing to be expected from the IACA programme is therefore a steadily in-creasing quantity of water pumped up to about 1980 with a decreasingrate of pumping thereafter, approach-ing the peak level by 1985. Thispattern is confirmed in the sequential analyses as can be seen from thegroundwater pumping by years shown in Figure 6. The slightly highergroundwa-ter delivery than in the IACA study is caused in 1975 by de-watering and in 1985 by overpumping; also there is slightly more pump-ing due to an assumption of higher recharge from rivers and link canalsthan in the IACA study. The effect of these factors on the tubewellpumping is very small.

Other aspects of Figure 6 which call for comment are the effectsof surface water storage and the relation of pumping in the historicriver flow sequences to pumping under mean year conditions. Theadvent of Tarbela storage which would be effective in the water year1975 might be expected to cause a reduction in tubewell pumping. None-theless the rate of increase in groundwater use is apparently unaffectedby the additional surface water made available from Tarbela. There arefive reasons set out below for this apparent anomaly:-

(i) The most important reason is that tubewells are usedup to the limits of their effective capacity to preventfurther rise cf a watertable which has risen to withinten feet of ground level. Very little overpumpingtakes place before the advent of Tarbela in the sequentialanalyses as pumping is limited both by the installed tube-well capacity and by the amount of the irrigation re-quirements in the project areas. Effectively, there-fore, because there has been but little overpumpingbefore Tarbela there is also no reduction in the ground-water pumping after Tarbela but instead there is anincrease due to the larger number of tubewells installed.

(ii) Many of the tubewell projects are still in a phase ofdewatering which would continue regardless of additionalstorage water.

(iii) The cropwater requirements used as input for the analysesare related in part to a rise in intensities due to theuse of Tarbela water outside tubewell project areas.

GROUNDWATER PUMPING BY YEARS

FIG. 6

(iv) It is assumed in the analyses that impounding atTarbela would not be possible until August 1974 withthe result that only five MAF would be released inthe water year 1975.

(v) The Tarbela release patterns are based on low rabirather than mean year river flow conditions and sosome surpluses would be passed to the sea in monthssuch as April and May. However, this point is largelyoutweighed by the requirements of balanced rechargein (i).

Between 1975 and 1980 extensive control of the watertable shouldbe provided by the tubewell projects. By this time it should bepossible under the IACA projections for the public tubewells to make useof the aquifer as a balancing reservoir with the amount of groundwaterpumping related to the availability of surface water. This potentialuse of aquifer storage is shown by the greater variations of thehistoric series from the mean year conditions in the later years of thestudy. The variations from mean conditions in the individual yearsare caused solely by the differences in river flows. It can be seenfrom Figure 6 that although these variations are significant they do notdiffer by more than about five per cent from the mean when considered ona yearly basis.

A further aspect of the control of the watertable is the amountof overpumping beyond the balanced recharge level. IACA concluded thata satisfactory average level for the watertable would be about 10 to 15feet below ground level but that temporary overpumping beyond thebalanced recharge level would be desirable at times of low surface wateravailability or prior to the introduction of new surface storage water.In the computer programme for the sequential analyses the recharge isbalanced by withdrawals from the aquifer at an average level of 10 feetbelow the ground when sufficient surface water is available. Pumpingbeyond the 10 foot level may be regarded as an overdraft on the aquifer.The cumulative totals for these overdrafts in the sequential studiesare shown in Figure 7. The overdraft is small before 1975 as it isrestricted to those areas in which public tubewells would already havecontrolled the watertable. A reduction of the overdraft in 1976 isevident in the mean year study due to the use of Tarbela water. Inthe historic sequences the overdraft actually increases at this timedue to low Chenab flows and consequent overpumping in the Punjab SCARPsin the case of the first historic series and due to low rabi flows inboth the Jhelum and the Chenab in the case of the second historicseries.

The amount of overpumping is not large but increases steadily after1976 until the total overdraft on the aquifer is approaching 8 MAF 1985in the mean year sequence. Some alleviation of this overdraft isprovided by reservoir releases at Sehwan/Manchar from 1982 onwards. Theoverdrafts in the historic sequences vary from year to year accordingto the monthly river flows, and these variations, shown in Figure 7

emphasise how sensitive the overdraft is to the river flow conditionsat any stage of development. By 1985 the total overdraft reachesabout 16 MAF in the first sequence and about 18 IIAF in the secondsequence or about double the overdraft in the mean year sequence.There are two reasons for this higher level of overpumping found inthe historic sequences. Firstly, as explained in Section 4.4, thetotal rabi flows on the Jhelum and Chenab in the historic period 1926-L6 are about 17 IIAF lower than under the 141 year mean conditions. Thisfactor alone is sufficient to account for the differences in over-pumping between the historic and mean year sequences and provides anindication of the way in which the system would be capable of over-pumping if faced with a series of low rabi years. The second reasonfor the higher rate of overpumping in the historic sequence is theconstraint imposed by canal capacities in certain commands. The effectof this constraint is that the overdraft on the aquifer cannot always bereplaced by additional surface water at times of high river flows.

The total overdraft of 8 MAF in 1985 with the mean year sequencewould be equivalent to a drawdown of less than three feet over theentire fresh groundwater area in the canal commands. In practice thedrawdown would be concentrated in certain canal commands but thisgeneral figure for the drawdown does indicate that the overpumpingwould not be at all excessive. Between 1976 and 1979 in the meanyear sequence the total overdraft is increasing at a rate of only about½2 YiAF a year which is very small in relation to the total irrigationdeliveries of about 100 MAF a year. The more rapid increase in over-pumping at a rate of about 1 MAF a year after 1979 is indicative of therising demand for storage projected in the IACA progranme.

The total figures for groundwater use are derived from the de-tailed figures calculated in the sequential analyses for individualcanal commands. The depth of watertable in the fresh groundwater areasis shown by years under the assumed method of system operation inFigures 8, 9 and 10 for Rohri, Panjnad and Abbasia and Lower Jhelumcommands. Rohri Canal command is selected as representative of theLower Indus Region and also because it has the greatest drawdown of anyof the commands in the basin under the method of analysis. By 1982the watertable is at a depth of over 40 feet in the mean year sequenceor over 70 feet after a series of low river flows in the first historicsequence, as shaon in Figure 8. After 1982, the overdraft on theaquifer is reduced by the introduction of storage water from Sehwan/Manchar and the enlargement of Rohri Canal. In practice a watertabledepth of 70 feet in this area may be unacceptable for technical reasonsand is certainly greater than envisaged by IACA. Some overpumping toraise intensities before 1982 was foreseen by IACA but not on this scale.However the depths shown in Figure 8 require clarification. The logicof the computer programme in its present form is not designed toeliminate drawdown by changes in surface water distribution. Inpractice the drawdown in Rohri could be alleviated by increasing pumpingin upstream commands and thereby releasing additional surface water foruse at Rohri in the rabi season.

In contrast to Rohri, the depth of the watertable in FaQn1adand Abbasia Canal commands is seen from Figure 9 to remain stablethrough the period of analysis. However, it should not be concludedthat all the overdraft at Rohri could be transferred to Panjnad andAbbasia. Part of the reason for the stable level of the watertablein Panjnad and Abbasia is that the canal capacities are adequate toreplenish the aquifer at times of high river flow. In any case thepumping could not be increased above the level of requirements in thiscommand. Nonetheless, it would be feasible to increase slightly theamount of pumping here and in the Trimmu commands in order to alleviatethe overdraft in Rohri.

The third command illustrated is Lower Jhelum Canal, whichdepends for its supplies on the Jhelum River with Mangla reservoir andcannot be served by the Indus (see Figure 4). In this command it canbe seen from Figure 10 that there would be some overpumping prior tocanal enlargement but the overdraft would be entirely made good before1985 by use of the enlarged canal combined with the projected additionallink canal capacity in the Punjab. Variations in the depth of thewatertable are attributable to the availability of surface water in theconditions of river flow used for the analyses. The watertable isgenerally deeper under the historic sequences due to the constraint ofthe canal system which prevents the same degree of aquifer replenishmentas would be possible under mean conditions.

Canals served by the Chenab River alone (see Figure )) are notillustrated as the watertable in these commands remains generally with-in the 10 to 15 foot range, in spite of the low rabi flows in thehistoric sequences.

(d) Link Canal System

IACA expected the existing and IBP link canal system to beadequate until about 1980 when they estimated that there would be arising demand for additional link capacity in the Punjab. An allowancewas made in the input data for an additional 0.3 MAF/month capacity inthe RQ and QB Links (see Figures 2 and 4) from the water year 1981onwards. This additional capacity in the sequential analyses isutilised in many months in the QB Link and in a few months in the RQLink.

Allowance was also made in the input data for ten per cent excessover the design capacity in the TSMB Link in all years. The excesscapacity seemed reasonable from the reports of early operation of theLink. Without the additional capacity there would have been someshortages in the canals served by the TSMB Link. In practice the short-ages could alternatively have been largely removed by using suppliespassed dowqnstream from the RQBS Link.

No capacity constraints were apparent in the others link canals.

- 33 -

(e) Use of Surface Storage

The IACA analysis projected a firm demand for storage on theIndus of about 5 MAF in 1975 rising to 9 MAF in 1985 under meanconditions of river flow. Projections for the period between 1975 and1985 were made by interpolation between the reference years.

The sequential analyses are operational rather than analyticalin nature and are therefore not suited to an evaluation of the IACAprojections for growth of stored water demand. While a generalassessment can be made of the use of surface storage water, it is notpossible to quantify the results.

The results of the sequential analyses are illustrated in Table5.8 which shows the breakdown of irrigation deliveries,in the mean yearsequence for the period November to April, before and after thecommissioning of Tarbela Reservoir.

Canal Head Diversions 24.3 29.9 5.6

River Outflow 1.2 1.8 o.6

The fact that river outflow during the period November to Aprilincreases by only 0-.6 RAF between 1974 and 1976 would seem to indicatethat nearly all the storage water is absorbed immediately. It cannothowever be deduced--that this represents a firm demand for storage sincethe computer proggramme will tend to utilise surface water in preferenceto groundwater.--The-,analysis is further complicated by the fact thatneither the capacity o'f tubewells nor the operation of reservoirs isbased on mean year-conditions but is geared to low rabi conditions.

A general examination of the results of the sequential analysisconfirms that a steadily rising storage requirement exists from 1972 on-wards under the IACA programme. In Figure 7, the pattern of overdraft onthe aquifer shows the drawdown increasing from 1977. Up to 1979 the

- 314 -

relatively small drawdown is in fact the result of the constraints inindividual canal commands, but beyond then the rate of drawdown ismore rapid which is an indication that Tarbela storage water is beingfully absorbed and that the system is becoming short of water again,as projected by IACA.

Between 1975 and 1985 the watercourse requirements during therelease period are increasing at a rate that is approximately linear.The same is true of the pumping capacity, and it is reasonable toconclude that tlhis will be also true of the storage demand.

5.3 POWER

(a) General

The sequential analysis provided an opportunity to compare theStone and Webster programme for power development with the systemdemands. The demands of the system are the Stone and W4ebster basicload forecasts, included as input data, and the groundwater pumpingloads computed in the analysis. The principal conclusions to be drawnfrom the results of the sequential studies are:

(i) there are deficiencies in peaking capability in theNorth Zone prior to commissioning of the first M4anglaunits;

(ii) minor and infrequent deficiencies occurring in theNorth Zone after completion of the inter-tie in 1973are met by transfers from the South Zone;

(iii) there are no deficiencies of peaking capability in theSouth Zone after 1971; prior to 1971 there may bedeficiencies in certain areas witlin the South Zonewhich would not be revealed by the analysis;

(iv) system peaking capability exceeds system demand for theentire period following completion of the North-Southinter-tie;

(v) there are substantial power transfers from North toSouth in the months of July through January after thefirst Tarbela units are commissioned.

The principal results of the analysis with regard to power andenergy generation appear in the summary sheets of the ccmputer print-out (Appendices B through C) which are generally self-explanatory.'Peak Reserve' - the difference between peaking capability and totalpeak load - is listed for each zone, and for the system. Ihen 'PeakReserve' is negative in the period 1973-1985 there is a 'Firm CapacityTransfer' having the same value.

- 35 -

In the North Zone, after Mangla is in operation, the hydro-plants will serve most of the power and energy demand, and the load-dispatching process adopted in the analysis has the effect of maximisingthe use of the hydro-plants and minimising the use of the thermal plants.It is believed that this method yields realistic values for the 'ThermalCapacity to Load's but the 'Thermal Energy to Load' would in practicebe somewhat greater than compuited and the 'Hydro Energy to Load'correspondingly less. This is because the thermal plants, in order tobe available at the time of peak demand, would be operating at partload during off-peak hours, although the hydro plants could meet theoff-peak load.

(b) Pumping Loads

The power and energy required for groundwater pumping arecomputed in the sequential analysis in contrast to the basic loads whichare input. Pumping loads are a significant part of the system demands.The annual energy demands for groundwater pumping within the canalcommands are tabulated in Table 5.9.

Monthly pealc power loads for the years 1975 and 1985, given inTable 5.10, indicate the magnitude and annual distribution of peakpumping loads. No interruption of service to tubewells was assumed inderiving these values.

In general the power and energy demands for pumping obtained inthe sequential analysis are lower than the values adopted as a basisfor the Stone and Wlebster development programme.

(c) Peak Reserves

The minimum reserve capacities of the system after the North-South inter-tie becomes effective are shown in Table'5.11. The peakreserves obtained in the sequential analysis are somewhat greater thanthose given in the Stone and Webster report. The principal reasonsfor the difference are firstly the lower pumping loads and secondly thehigher hydro peaking capability obtained due to the method of calcula-tion in the sequential analysis. Table 5.12 presents a comparison ofresults for the critical water years 1976 and 1985, in which adjustmentshave been made to place the figures on a similar basis.

Transfers of power between zones obaained in the mean yearanalysis for 1976, 1980 and 1985 are given in Table 5.13. Transferswere not limited by inter-tie capacity, since a large capacity wasadopted for the inter-tie in order to determine the potential for inter-zone power transfers.

5.4 RESMVOIR OPERATION

Since the reservoirs are influenced by both irrigation and powerconsiderations we have dealt with them under a separate heading. To

- 38 -

draw any justifiable conclusions on reservoir operation it is necessaryto examine the subject on a time interval that is shorter than themonthly base used in the study. Nevertheless it is possible to commenton three aspects of reservoir operation, namely drawdown levels, outletcapacities and release patterns.

(i) Drawdown Levels

The results of the analysis seem to confirm the view that theMangla reservoir should be drawn down to the 100h level when required.In the pre-Tarbela period there would in general be a need for as muchwater as can be made available from the reservoir. Nothing arose inthe analysis to suggest any alteration in the Tarbela drawdown level of1332.

(ii) Outlet Capacities

The outlet capacity at Mangla of four tunnels has certainrestrictive effects. It causes the involuntary impounding in a meanyear of 0.3 MAF in April and it is not even possible to pass the fullreleases in March that were projected in the IACA plan. While noshortages were apparent in April, they did arise in March.

(iii) Release Patterns.

The justification for the release patterns adopted is thatrelatively few shortages arose after 1975, and such shortages as arosebefore 1975 could not be much alleviated by altering the MIangla releasepattern. Two points regarding the release patterns, however, may needfurther consideration. Firstly it may be necessary to increase Manglareleases in October during months of low flow. Secondly releases fromTarbela in April and iMay tend to be wasted to the sea up to 1980 underconditions of mean flow. Such releases are, however, needed to counter-act low flows in these months, and they serve the dual function ofreducing groundwater pumping and at the same time increasing hydrocapability in the months of lowest peak reserve. Fairly severe short-ages can occur on the Indus in April and May which is the criticalperiod for the sowing of kharif crops and a small retention in thereservoir up to the first ten days of M4ay will act as a safeguard. Asa rough indication of the effect on peaking capability of storage inApril it can be calculated that every 0.1 M4AF stored during this monthis equivalent to increasing the peak reserve of the system by a valuevarying from 20 megawatts in 1977 to 30 megawatts in 1985. Thus thedrawing down of the Tarbela reservoir by the end of Yarch would requirea compensating increase in peak reserve of the order of 200 megawatts,which may be a high price to pay for extra releases in the early part ofthe year.

The general form of the river routing equation is

RL = (GF x Q2) - (SF x Q1 )

Where RL = nett loss (+) or gain (-) in the reach

SF = channel and bank storage factor for thereach (see table above)

Q 2 = volume of inflow to the head of the reachduring the current month (includes tributary inflow)

Q1 = volume of inflow to the head of the reachduring the previous month

LF = channel loss factor (permanent seepage andevaporation)

GF = LF + SF and is shown in the table above.
