IAHS Newsletter Seventh UNESCO/IAHS Kovacs Colloquium:Scales in Hydrology and Water Management

The publication illustrated is the pre-published proceedings

of the seventh Kovacs Colloquium held on 17–18 September

2004 at the headquarters of UNESCO in Paris, France. The

George Kovacs Colloquium is an event traditionally

organized by the International Hydrological Programme

(IHP) of UNESCO and IAHS just prior to the biennial

sessions of the Inter-Governmental Council of IHP. Its goal is

to provide an opportunity for delegates and other participants

coming to the Council sessions to attend a brief and highly

stimulating scientific event: leading scientists solicited to

provide state-of-the-art reviews in topical areas of hydrological

research. This facilitates the international exchange of new

ideas, addresses their most relevant applications, as well as

drawing attention to open questions and unresolved problems

for ongoing research. It is also open to any IAHS member.

It is notable that a decade after the first Kovacs

Colloquium that was devoted to Space and Time Scale Variability and Interdependence in Various Hydrological Processes, the seventh Kovacs Colloquium returned to this

fundamental question of Scales in Hydrology. Indeed,

hydrology is primarily the science concerned with the

circulation, distribution and properties of the water of the

Earth and its atmosphere across the full range of space and

time scales. However, the significant theoretical and applic-

ation developments that have occurred during this decade

suggest a need to widen the scope of the question to include

Water Management, and also to focus on the possible

development of applications from cutting edge research to

Integrated Water Resources Management (IWRM). The topic

of scales in the hydrological sciences and in water resources

management in general was accepted by the 35th session of

the IHP Bureau as a contribution towards IHP-VI. This topic

also strengthens the continuing collaboration between

UNESCO-IHP and IAHS, especially in the new Prediction in

Ungauged Basins (PUB) initiative.

The present book was designed to provide detailed and

comprehensive reviews on the current theoretical and

experimental applications of scale concepts in hydrological

sciences. In order for the book to reflect existing trends acc-

urately, nothing has been done to resolve some divergences

*IAHS Publ. 287, ISBN 1-901502-62-7, £36.95

between the viewpoints on the scale concepts expressed in

the various chapters, nor to present a unified view. Along

with discussing fundamental challenges and research direc-

tions, the book demonstrates the crucial importance of scale

issues for water management.

The cover picture of this book is the work of Andre

Martins de Barros (Miroirs du temps), and it provides a self-

contained synopsis of the complex evolutionary processes

acting across the space–time scales, which overall were

discussed during two days of the seventh Kovacs Colloquium

with respect to hydrology and water management.Ioulia Tchiguirinskaia

President’sPieceFrom Kuni Takeuchi

Severe cyclones and floods hit many

parts of the world in September and

October. In the Caribbean and southern

USA, several hurricanes hit and over a

thousand lives were lost. As always, the

poorest were the most tragically effect-

ed, losing their only possession, their

lives, as in Haiti. Japan received several

major typhoons and torrential rains

causing many casualties and much dam-

age. They also caused the early fall or

immature growth of nuts and fruits in

the forests, which has made animals

suffer from serious food shortage. Recent-

ly, many bears have come down to

villages for food and some have been

been killed each day because of their

threat to people. I am so sorry for the

bears who are only desperate to make

preparations for their winter sleep.

GEOSS I attended a series of major meetings

recently. The first (University of

Washington, Seattle, 30 September–

1 October) was a users workshop to

review the GEOSS (Global Earth

Observation System of Systems) draft

implementation plan on the theme of

water, and was organized by US and

Japanese hydrologists led by Professors

Toshio Koike and Eric Wood. GEOSS

is a G8 Summit initiated plan for global

observation. Its 10-year plan is in

preparation and will be decided at the

Third Global Observation Summit in

Belgium, February 2005. It will bring a

major investment to secure the global

observations necessary to achieve the

UN MDGs (United Nations Millennium

Development Goals) and Johannesburg

commitments. The importance of in situmeasurements and the need for

demonstration projects to show local

people the benefits of GEOSS, has been

stressed. Hydrologists’ comments and

contributions are awaited; do respond to

the requests for open review on the draft

10-year implementation plan. The first

governmental review is until mid

November. For more information, see

http://earthobservations.org/.

PUBA splendid PUB Workshop was

convened in Moscow (7–10 September)

by Professors Enda O’Connell and Lev

Kuchment. It was the NATO Advanced

Research Workshop on: Physical Models of River Basin Runoff and Their Application to Ungauged Basins. Some

25 scholars participated, including a

number of young scientists from eastern

European countries. It was one of the

most advanced hydrological meetings I

have ever attended. Key questions were

discussed in depth and all felt that PUB

has really lifted off. Later, many of us

went to St Petersburg to visit the

Hermitage and Peterhof, the World

Heritage Queen Ekaterina collections

and beautiful fountain works. I was

warmly received by Prof. Igor

Shiklomanov and his colleagues of the

State Hydrology Institute (SHI). An old

plate on the wall of the SHI building

was impressive; it marks the height of

the disastrous storm surge flood of 1924.

Now a 25 km long anti-tidal barrage

complex is under construction in the

Bay to protect the city of St Petersburg;

it is two-thirds complete.

UNESCO-IHP Intergovernmental Council Preceded by the Seventh Kovacs

Colloquium on Scales in Hydrology and Water Management, with very focused

high-level presentations, and an IAHS

Bureau Meeting, the 17th Session of the

IHP Inter-Governmental Council was

held at UNESCO, Paris on 20–24

September.

The main agenda item was the

governance of the IHP Council, which I

regret took too much time and energy to

leave much for discussion of other

substantial matters. Nevertheless,

Arthur, Pierre, John Rodda and I took

the floor a number of times and showed

our interest in contributing to IHP such

as on International Flood Initiatives and

IHP-VII (2008–2013). During the IAHS

activity report, we announced that the

International Hydrology Prize 2004 was

awarded to John Rodda for his

outstanding contribution to hydrological

sciences and he got a huge applause.

During the Japanese reception for the

UNESCO auspices International Center

for Water Hazards and Risk

Management, the same happened to

Pierre Hubert when we announced that

he has been awarded the French

“Légion d’honneur” for his activities in

the field of Environment.

Well, IAHS seems to be doing quite

well. But we have to look to the future. I

urge you, as individuals, to respond to

our president-elect Arthur Askew’s call

for comments on IAHS. I very much

appreciate his lead to reflect this funda-

mental relation as IAHS is made up

solely of individual members.

Finally, do submit your abstracts to

Foz if you have not already done so, and

plan to assemble there for excitement.

Some four years ago, Professor Kuniyoshi Takeuchi, the then

President-elect of IAHS, invited the broad community of

IAHS to join him in developing new initiatives that he might

take up in 2002 when he became President of the Association.

He received many replies and from these he distilled the

plans for what is now the PUB initiative.

As PUB nears the end of its initial phase, I find myself in

the same position as Kuni was four years ago. In July 2003 I

was honoured to be made President-elect of the Association

and I am now looking ahead to the Assembly in Foz when I

will take over from Kuni the mantle of the President. It is said

in English that “imitation is the sincerest form of flattery”

and I therefore make no secret of the fact that I am copying

Kuni’s action of appealing to the broad IAHS community to

provide ideas as to the direction that IAHS might take over

the coming four to five years.

However, there is one difference between Kuni’s and my

call for comments. Kuni sought ideas for a new initiative. In

order to make PUB successful, it will need all the help we

can give it and so I do not think that we should launch any

new initiatives at this time. Therefore, my call is for ideas as

to how the Association might better serve individual

hydrologists.

I have long experience with the workings of international

organizations, both positive and negative. From this I

recognize that, while rules are important, it is only through

personal initiative and responsibility that anything of value is

achieved. I am also acutely aware of the difficulties faced by

those hydrologists, particularly, but not only, in developing

countries, who feel cut off from the mainstream of

hydrological science, but have much to offer the wider

community from their own particular experience. These are

just two of the aspects of the Association’s work that will be

high on my personal agenda for the next few years.

With this in mind, I would therefore seek your comments

on two topics:

1. IAHS has an active and wide-ranging publication program-

me; it organizes and co-sponsors a series of major scientific

meetings; and it seeks to maintain contact with the wider

hydrological community through its Newsletter and website,

as well as by establishing links with relevant national and

regional bodies which promote the hydrological sciences.

How well do these activities serve you as an individual hy-

drologist? Which of them do you find the most valuable and

how might they be improved? Which of them do you find

of least value and how might these be made more useful?

2. As an international non-governmental organization, it is

important that IAHS has a formal structure and a set of

Statutes and By-laws. These may be found on the IAHS

web site. It is also important that the Association maintains

the formal links with the national and regional bodies

referred to under 1 above. All of these elements help to

officially define IAHS, but they do not themselves give it

life. This can only be achieved when individuals work

with and within this structure to promote the hydrological

sciences. To what extent do you feel that, as an individual

hydrologist, you are a part of the Association? Do you see

IAHS as “your” Association? If not, why not, and what

might be done to increase your sense of belonging to IAHS?

No-one has much time to spare these days, but I would urge

you to spend at least five minutes thinking about these matters

and five more minutes sending me your views.

All inputs will be welcome, whether as a two-line e-mail

message or a ten-page letter. Please feel free to respond by

e-mail or by post in English, French, Spanish or Russian. I

would be happy to discuss matters with you by telephone (in

English or French), if you would find that more convenient.

I await with interest your comments on these two import-

ant topics.

Hydrologist makes the Guinness Book of World Records

IAHS Member, Dr Ritesh Arya, has

been working in the Himalayas for the

last 15 years to find sustainable water

solutions by exploring and tapping

groundwater resources. For the last

seven years he has specialized in

exploiting groundwater resources in the

high altitude cold mountain deserts of

the Ladakh Himalayas.

In doing so, besides gaining valuable

groundwater and subsurface geological

data, his team has achieved various

firsts. His name is now in the Guinness Book of World Records for exploring

and drilling the highest borewell for

groundwater development with artesian

conditions, at an altitude of >11 000 feet

in Ladakh.

Dr Arya commented “I think this is a

proud moment for everyone who is

associated with the development of

hydrogeological sciences, especially in

the mountain regions where conditions

are tough and research material avail-

able for consultation of water resources

is almost non-existent”.

Congratulations Dr Arya!

IAHS AND THE INDIVIDUAL HYDROLOGIST – A call for comments From Arthur Askew, IAHS President-elect


A cornerstone of the PUB Science Plan (Sivapalan et al.,2003

*) is the formation of working groups. The role of the

working groups is to identify common hydrological

objectives for prediction. Members of the working groups are

then asked to evaluate a range of methodologies for achieving

the specific common objective. The emphasis of the working

groups’ output is the comparability of methodologies. Work-

ing groups are envisaged as self-organising, but with the

constraint that common objectives are identified and that, if

at all possible, predictions are made with the associated

uncertainty quantified.

The rationale for this is that, as hydrologists, we tend to

develop our own methods and models but rarely evaluate our

approaches with regard to other existing schemes. A further

rationale is that synergies may become apparent between

techniques with the hope that we may develop new approaches

to the PUB problem through this sharing of experience and

insight. It is often noted that much of the new, interesting

science is done through inter-disciplinary approaches on the

boundaries of traditional science themes. We hope that

through such informal groupings of active researchers with

diverse approaches yet common aims, we will make signif-

icant progress on the PUB problem.

The recent successes of the MIPs (Model Intercomparison

Projects), such as PILPS (Project for the Intercomparison of

Land Parameterisation Schemes) and AMIP (Atmospheric

Model Intercomparison Scheme) show a way forward. In

these MIPs, many developers of models are brought together

with specific common objectives. The results have been

widely disseminated and key lessons drawn on model

applicability and relative performance. In this way, we hope

that the PUB working groups will achieve similar synergies

through the objective comparison of alternative method-

ologies for making predictions within ungauged basins.

The International IAHS-PUB Workshop held in Menaggio, Italy, July 2004

The IAHS “Decade on Prediction in

Ungauged Basins (PUB)” initiative is

rapidly gaining momentum and energiz-

ing the hydrological community. The

initiative aims to increase our under-

standing of how hydrological systems

work and how they can best be describ-

ed by mathematical models. Success is

to be measured by the reduction of

uncertainty in the predictions from such

models. At the heart of the PUB

initiative, therefore, is a commitment to

quantify the uncertainty in hydrological

flux predictions.

Prediction uncertainty stems mainly

from model parameters and structure,

measurements of input and output data,

and initial and boundary conditions.

However, methods to estimate and

propagate this uncertainty are limited in

their ability to distinguish between the

various sources of uncertainty, and in

their ability to guide improvements to

the model structure. In fact, there has

been a general lack of progress in

methods for estimating uncertainty in

hydrological and environmental models;

we appear to have been stuck at the

same questions with poor understanding

of how to proceed.

To address this issue, a PUB

Working Group on Uncertainty Analysis

in Hydrological Modelling (WG-

UAHM) has recently been implemented,

with the goal of advancing and guiding

research into uncertainty estimation and

model evaluation (diagnostic) theory

and techniques for hydrological science

and for operational use. Two fundamental

science questions drive the activities of

this working group:

– How can all sources of uncertainty be

explicitly estimated and propagated

in hydrological modelling?

– What is an appropriate framework

for model/method evaluation under

uncertainty?

The first action of the group was to

convene the international workshop on

Uncertainty Analysis in Environmental Modelling at the Villa Vigoni in

Menaggio, Italy, located on beautiful

Lake Como. The three-day workshop,

organized by Jim Freer, Thorsten

Wagener and Erwin Zehe (with the able

advice of Keith Beven, Hoshin Gupta

Progress on PUB Working Group Formation

Uncertainty Analysis in Environmental Modelling


Participants in the Uncertainty Analysis in Environmental Modelling workshop at Menaggio, Italy, July 2004

and Andras Bardossy) was held in early

July 2004 and attended by a hetero-

geneous and international group of 26

scientists. The format of the workshop

was based on the premise that, while the

usual (presentation based) conference

style is good for conveying knowledge,

it is weak in terms of encouraging

interaction and stimulating new ideas.

The organizers designed, instead, a

workshop format that focused on

discussions and brainstorming, with

only limited time allocated to present-

ations of existing and already well-

known work. Younger scientists were

solicited to make the few presentations

that were invited, with the majority of

the time allocated to small group

discussions.

The objectives were:

– To promote discussion and critical

appraisal of the current state-of-the-

art of uncertainty analysis techniques

employed in environmental modelling.

– To stimulate/introduce new ideas

which are not currently part of the

core hydrology calibration/

uncertainty road map.

– To work towards a stated set of

beliefs or principles about the main

themes explored in the workshop

(includes agreements and disagree-

ments and, most importantly, the

reasons for disagreements).

– To work out what we believe to be

the future trends and possible

directions for our science.

– To define future activities for this

working group on uncertainty.

The objectives were translated into a list

of major science questions that served

as the focus for the discussions:

Q1 What is the current state-of-the-art

of uncertainty analysis in environ-

mental and hydrological science

and in other relevant fields?

Q2 What are the limitations and

problems of current methods? What

are the bottlenecks that prevent

progress?

Q3 What are promising directions for

progress in uncertainty analysis in

environmental and hydrological

science?

It is fair to say that the participants

found the workshop to be an incredible

learning experience, while providing

sufficient time to explore and digest the

beautiful environment and to get to

know other scientists over a glass of

Italian wine. Future workshops with a

similar style but with different foci have

been suggested and are being planned.

The results of this workshop will be

published shortly in a scientific journal.

In conjunction with this workshop,

an international experiment to compare

uncertainty estimation techniques using

a common data set and a common

model has been initiated. The Hydrologic

Uncertainty Group Experiment (HUGE)

is designed to be the first in a series of

experiments that will help us understand

the effects of different modelling ass-

umptions on predictive uncertainty and

what approaches might be suitable for

specific situations (i.e. basin X under

data conditions Y and with modelling

objectives Z). The HUGE 1 experiment

uses a simple precipitation-potential

evapotranspiration-runoff data set and a

lumped conceptual model and is open to

all; information about how to participate

can be obtained from the first author.

group can be found at: http://www.hwr.arizona.edu/uncertainty

Sediment Transfer Through The Fluvial System

edited by Valentin Golosov, Vladimir Belyaev & Des E. Walling

IAHS Publ. 288 (August 2004)ISBN 1-901502-67-8, 498 + x pp. Price £85.00

An improved understanding of sediment transfer, storage and redistribution has many important practical applications, including soil

conservation, catchment management, control of diffuse-source pollution, predicting and managing reservoir sedimentation, and the maintenance of irrigation systems and

navigation channels, which link closely to the sustainable management of land, water and

other natural resources. Problems of understanding sediment redistribution and storage in different

components of the fluvial system within many different regions of the world are addressed in this volume, which is the proceedings of the symposium, co-sponsored by IAHS-

ICCE and UNESCO, held in Moscow (August 2004). It is a contribution to the

International Sedimentation Initiative (ISI) of the UNESCO International Hydrological

Programme (IHP VI).

Executive Summary of Workshop Report, 8–10 March 2004

HEPEX Goal HEPEX aims to bring the international

hydrological and meteorological comm-

unities together to demonstrate how to

produce reliable hydrological ensemble

forecasts that can be used with confi-

dence by the emergency management

and water resources sectors to make

decisions that have important conse-

quences for the economy, and for public

health and safety.

The main scientific theme of HEPEX

will be how hydrological forecast

uncertainty can reliably be quantified at

each step of the forecast process and

then communicated to, and applied by

the end users.

HEPEX is an independent, coopera-

tive international scientific activity that

is affiliated with several international

organizations and with many other

organizations interested in hydrological

ensemble prediction as well. Particip-

ation in the HEPEX project will be open

to anyone who may wish to contribute

to help meet its goal. The project will

maintain a list of participants and will

keep them informed about HEPEX

activities that may be of interest to them.

Primary leadership of the HEPEX

project is the responsibility of a science

steering group that will be composed of

representatives of organizations affilia-

ted with the project. A User Council

composed of representatives of organiz-

ations with a strong interest in using or

applying HEPEX results will oversee

HEPEX activities.

Many scientific questions need to be

addressed for operational hydrological

ensemble forecasts to be used to their

full potential. Meteorological aspects of

ensemble prediction include issues such

as:

– What are the requirements of

ensemble weather forecasts to

support hydrological prediction?

– Do the existing meteorological

forecasts account for important

meteorological and climate

uncertainties?

– What is the role of operational

forecasters?

– What are the scientific questions and

issues that need to be addressed to

meet requirements?

Hydrological ensemble prediction in-

volves integrating many sources of

uncertain information and accounting

for how hydrological processes would

behave in response to this information.

Sources of uncertainty include future

weather and climate forcing, initial

hydrological conditions and uncertainty

in model representations of hydrological

processes. Because hydrological models

are imperfect and because of limitations

in representing important sources of

uncertainty, the raw ensemble forecasts

produced by hydrological ensemble

forecast systems may contain complex

biases that must be removed to meet

user requirements for reliable ensemble

forecast information.

Data assimilation is required in

hydrological ensemble prediction to

process available observations to prod-

uce the best possible probabilistic

estimates of initial hydrological condit-

ions. These estimates must include

ensemble members as well as prob-

abilistic distributions of individual state

variables. The ensemble members must

represent the appropriate joint variable

structure, both among state variables at

a given location and spatially, of equally

likely possible initial states.

Hydrological modelling issues that

are important to HEPEX include:

– What are the sources of uncertainty

in hydrological models?

– What are the implications of

hydrological models being imperfect

representations of real hydrological

systems?

– How can uncertainties in hydro-

logical models, model parameters

and hydrological initial conditions be

represented in hydrological ensemble

prediction?

Verification is essential to HEPEX

because we must be able to measure the

accuracy and reliability of our results.

This is important to our users. It is

important to measure progress toward

our scientific objectives. And it import-

ant to assure that improvements are

being made to operational forecast

systems.

To address user needs and science

issues to meet these needs, HEPEX will

organize a set of cooperative activities

that include test beds, inter-comparison

experiments, as well as scientific work-

shops and meetings. One objective of

the project will be to develop a pilot

capability for hydrological ensemble

prediction that could be used by

hydrological services throughout the

world. The results would be demons-

trated through test beds, inter-

comparison projects and by application

by operational hydrological services,

water resources agencies and other users.

For HEPEX to achieve its goal it

must have strong mutually supportive

ties to other international programmes.

These include programmes to: improve

weather and climate forecasts; provide

new global sources of data and improve

existing sources, especially satellite data

and surface observations; to develop

improved data assimilation techniques,

and to improve hydrological forecasts.

The HEPEX programme from its

inception must be an evolutionary and

adaptive programme. The programme

needs to be responsive to funding

opportunities, proactive in fostering

collaborative partnerships among

academia, operational centres and the

private sector (e.g. THORPEX, USWRP,

etc.), and aware of relevant

breakthroughs and their impact on

defining new directions for the

programme. The foundation of such a

programme starts with its governance.

HEPEX must implement governance

that reflects one of a true international

effort, with leadership drawn from its

global “stakeholders” who are actively

involved in hydrometeorological

prediction and use of such predictions.

Statement of Importance and Urgency Ensemble forecast techniques are

beginning to be used for hydrological

prediction by operational hydrological

services throughout the world. These

forecasts are important because they not

only offer an estimate of the most

probable future state of a system; they

also provide an estimate of the range of

possible outcomes. Indeed, many users

are risk-averse. They often are more

concerned with having a quantitative

estimate of the probability that

catastrophic effects may occur than with

knowing the most probable future state.

Not only does ensemble prediction in

hydrology offer a general approach to

probabilistic prediction; it also offers an

approach to improve hydrological fore-

cast accuracy as well. John Schaake

HEPEX – the Hydrological Ensemble Prediction Experiment


Drought is a major natural hazard and

water resources and ecosystems are

under great stress in times of drought. A

thorough understanding of droughts and

an assessment of their impact on the

environment, society and economy are

therefore important. As droughts

normally cover large areas, and aquifers

and rivers cross national boundaries, a

transnational approach to hydrological

drought estimation and management

should be sought.

The ASTHyDA project addresses,

through a consortium of primarily

European experts, 19 participants from

nine countries, the need for a concise

review and dissemination of recent

knowledge and tools for prediction of

streamflow and groundwater in periods

of water scarcity. This also includes the

possible impact of environmental

change, e.g. land use and abstractions,

on hydrological droughts.

Amongst the major achievements in

the project is a textbook on hydrological

drought published by Elsevier in the

series Development in Water Science,

in September 2004. As elements

included in providing feedback in the

preparation of the textbook were two

workshops and an international study

course. A final aim of ASTHyDA was

the establishment of the European

Drought Centre (EDC), a virtual know-

ledge centre to better coordinate drought

related activities in Europe. These

activities are described in more detail

below.

Textbook on hydrological drought Hydrological Drought – Processes and Estimation Methods for Streamflow and Groundwater (ed. by Lena M. Tallaksen

& Henny A. J. Van Lanen) is a textbook

aimed at university students, practising

hydrologists and researchers. The main

scope is to provide the reader with a

comprehensive review of processes and

estimation methods for streamflow and

groundwater drought. It includes a

qualitative conceptual understanding of

drought features and processes, a

detailed presentation of estimation

methods and tools, practical examples

and key aspects of operational practice.

The methods are demonstrated using

sample data sets and tools that are

provided on the accompanying CD. The

drought phenomenon and its diversity

across the world are illustrated using a

global set of daily streamflow series,

whereas regional and local aspects of

drought are studied using a combination

of hydrological time series and

catchment information. The book con-

cludes with human impacts, ecological

issues and examples of procedures for

designing and operating water resources

schemes. A majority of the examples

are taken from regions where the rivers

run most of the year. The material

presented ranges from well-established

knowledge and analysing methods to

recent developments in drought research.

Its nature varies accordingly, from a

more traditional textbook with its clear

overview to that of a research paper,

which introduces new approaches and

methodologies for drought analysis.

Water Management Workshop (27–28 March 2003)

The purpose of the workshop was to

present a first draft of the textbook to a

group of European water management

experts and incorporate feedback from

the discussions into an improved second

draft of the book. Thirteen water man-

agers from 11 different European coun-

tries attended, with two representatives

from each of The Netherlands and

Norway. The water managers brought a

wealth of experience on a wide range of

low flow and drought issues to the

workshop, with several participants lead-

ing national teams to establish policy

and manage water at a national scale.

European Experts Workshop (29–30 March 2003)

At the second workshop the first draft of

the textbook was presented to a group of

European experts from the Medi-

terranean countries. The various

chapters of the book were presented by

the lead authors, and again the

comments from the experts were

incorporated into the second and

improved draft. The 17 invited experts

from the Mediterranean countries

belonged to research organizations or

universities in Algeria, Tunisia,

Morocco, the Palestinian Authority,

Romania, Macedonia, Malta, Iran and

Bulgaria. They contributed a profound

knowledge and experience on low flow

and drought issues, especially from

water shortage regions, to the workshop

and stimulated the discussions with their

view on the methodologies and tools

presented in the book. They showed

examples from their regions and

stressed the need for such a compre-

hensive book. In addition, it was

important to receive the feedback of the

experts on the book with respect to its

use as teaching material.

International Study Course (30 September–4 October 2004)

An International Study Course on

Hydrological Drought, was organized

by Alterra, Green World Research

Institute, and Wageningen University.

Twenty-seven students attended, 19

came from Europe, the others came

from Algeria, Argentina, Bangladesh,

Morocco, Mauritius, Palestine, Puerto

Rico, and Tunisia. The course was

taught by 15 instructors who are authors

of different chapters. In plenary sessions,

each chapter of the draft textbook, the

global dataset and the estimation tools

that are on the accompanying CD were

briefly introduced. Three parallel

sessions were organized:

– Statistical modelling of drought

– Physical-based modelling of drought

– Setting in-stream ecology

requirements

In each session, a group of students

worked on a case using data and

estimation methods that are described in

the textbook and available on the CD. In

the final session, each group of students

presented their case to the plenum.

Students and teachers discussed

possible improvements of the textbook,

the CD and the course. The students

evaluated the study course as good to

very good. Most of them learned a lot

and all particularly appreciated the

international working atmosphere. The

second draft of the textbook and the CD

benefited from the critical comments by

the students.

After completion of the textbook it is

planned to hold similar courses in

different parts of the world using the

final textbook as a teaching aid. Funding

possibilities for the organization of

these courses are currently being eval-

uated. Organizations that would like to

host a course are kindly invited to

The European Drought Centre One aim of the ASTHyDA project is to

contribute to the establishment of a pan-

European partnership on drought fore-

casting, monitoring, estimation and man-

agement. Based on the network estab-

lished through the workshop, expert

meeting and study course and through

contacts with existing networks, the

European Drought Centre (EDC) has

been established. The EDC is a virtual

knowledge centre with the aim to

coordinate drought-related activities in

Europe to better mitigate the environ-

mental, social and economic impacts of

droughts. The EDC will promote collab-

oration and capacity building between

scientists and the user community and

thereby increase preparedness and

resilience of society to drought. The

centre will ensure a regular exchange of

information and expertise on drought in

the future.

Five main objectives have been

identified:

(a) The EDC will work towards a better

understanding of the drought pheno-

menon and provide the necessary

link between science, policy and

operational management.

(b) The EDC will act as a platform to

initiate and discuss scientific

progress on drought research within

academic society, but, as important,

will be a meeting place between

multi-disciplinary experts involved

in drought research and manage-

ment, including other technical and

socio-economic disciplines. It will

thus ensure a regular exchange of

information and assist in integration

of new knowledge in

multidisciplinary sectors.

(c) The EDC will help to solve society-

driven water related problems. It

will act as a forum for discussion on

policy issues related to sustainable

water resources management in a

pan-European context, e.g. implica-

tions of the EU Water Framework

Directive on low flow and drought

management.

(d) The EDC will liaise with inter-

national organizations and program-

mes such as EEA, UNESCO-IHP,

WMO-HWRP, IAHS, EU frame-

work programmes, international

river commissions (e.g. Meuse,

Danube) and regional drought

centres (e.g. USA and South Africa).

(e) The EDC will work towards estab-

lishing a European Drought Watch

System, at its initiation focus is

given to drought forecasting and

monitoring, as well as supporting

the developing national drought

mitigation plans based on best

practise guidelines.

The Water Resources Systems – Global

Change, Risk Assessment and Water

Management symposium: (HS02), that

was convened by the commission with

support from ICASVR, ICSW and

ICWQ during the General Assembly of

IUGG 2003 in Sapporo, was a very

successful scientific event. The theme

addressed a wide range of problems and

many contributions were submitted. In

total 80 papers were accepted for oral

presentation, 106 abstracts were

accepted for poster and short oral

presentation and 105 abstracts for poster

presentation only. The large number of

accepted papers resulted in two volumes

in the IAHS Red Book Series:

Publ. 280: Water Resources Systems—Water Availability and Global Changecompiles a representative sample of the

range of activities currently engaging

the international hydrological science

community, focusing on:

– Water resources assessment case

studies and methodologies,

– Observations of hydrological change,

– Coupled climate–land surface

modelling approaches,

– Water quality threats to water

resources, and

– Modelling approaches to water

resource assessment.

Publ. 281 Water Resources Systems—Hydrological Risk, Management and Development addresses:

– Flood risk: analysing trends and

processes,

– Modelling flood runoff,

– Drought risk: analysing trends and

processes,

– Management of reservoir systems,

– Water resources management

policies,

– Water resources management:

methods and case studies, and

– Integrating water resources

management.

2004This year the commission has supported

the Sixth International Conference on

Hydroinformatics held 21–24 June 2004

in Singapore, at which new applications

and developments in artificial neural

networks, evolutionary algorithms, fuzzy

logic, optimization, decision support

and management systems, uncertainty

and risk analysis were presented.

In September 2004 the Workshop on Modelling and Control for Partici-patory Planning and Managing Water Systems, co-sponsored by ICWRS was

held in Venice, Italy, focusing on the

role played by modelling and control

techniques as well as software engin-

eering in designing Multi-Objective

Decision Support Systems (MODSS)

for planning and managing water

resource systems with an integrated and

participatory approach.

2005The ICWRS contribution to the Seventh

IAHS Scientific Assembly, in Brazil

next April, symposium S2, is under

preparation. The topic is: Sustainable

Water Management Solutions for Large

Cities. In total 49 papers are accepted at

present; another 13 papers have still to

be modified. The accepted papers cover

a wide range of topics. Some contribu-

tions relate to the impacts of urbani-

zation on local and regional hydrology,

while other papers are dedicated to the

specific conditions of urban water man-

agement with regard to socio-economic

and ecological conditions. Flood risk in

urban areas is also a major topic.

ICWRS is also organizing a

workshop: Hydrological basis of dam

safety with respect to floods, at the

Assembly (W3). Its focus is the

problems of design floods for obtaining

a required dam safety level at sites with

limited data availability. Its main aim

consists of making recommendations

Water Resource Systems, ICWRS


for hydrologists faced with the problem

of design flood estimation in data-poor

regions.

On behalf of IAHS, ICWRS is taking

part in preparations for the: International Conference on Integrated Assessment of Water Resources and Global Change: a North–South Analysis, 23–25 February

2005 in Bonn, Germany. Dan Rosbjerg

is representing IAHS and will give an

invited talk at the event.

ICWRS will participate in the special

session of: Innovative perspectives of integrated water resources management under the changing world conditions at

the XXXI IAHR Congress, Seoul, 2005.

President-elect of ICWRS Hubert

Savenije, will give an invited

presentation about the view of IAHS on

this topic. Other invited speakers will

present the approach of similar

organizations (IWRA, IWA, IAHR).

Future The next conference of the ICWRS-

series on Integrated Water Resources Management is planned for 2006, and

will probably take place in Germany.

During the IAHS General Assembly,

Sapporo (Japan, July 2003), a group of

scientists discussed the fate and future

of the IAHS International Commission

on Atmosphere–Soil–Vegetation Relations

(ICASVR). A consensus emerged that a

major change in direction was required

for this commission to be successful,

away from the technical details of

modelling atmosphere–soil–vegetation

interactions, towards the use and the

usefulness of hydrological information

in water resources decision making. A

new name was required, to make a clean

break with the past, and so the

International Commission on the

Coupled Land–Atmosphere System

(ICCLAS) was born.

The main goal of the ICCLAS is to

promote the evaluation and usage of

outputs generated by global/regional

coupled land–atmosphere models for

water resources applications, including

the management of floods and droughts.

Such models can provide decision

makers with valuable knowledge regard-

ing the effects of climate variability and

change, and the impact of land surface

heterogeneity on the spatio-temporal

distribution and availability of fresh-

water resources at the national/

regional scale. In addition, even simple

indices to monitor climate variability

phenomena, e.g. ENSO, can often

present useful information in this

context. The need for such information

is becoming increasingly urgent in those

parts of the world where stresses on

available water resources are growing

most rapidly as demand expands while

quality deteriorates. This need becomes

even greater with the continuing

decrease in funding for observational

networks. The activities of this

commission are, in particular, intended

to benefit decision makers in less

developed countries (LDCs) where

resources for model development and

data collection tend to be limited.

The first major activity of the new

commission, a symposium on the

Regional Hydrological Impacts of Climatic Variability and Change with an Emphasis on Less Developed Countries will take place during the

next IAHS Scientific Assembly (Brazil,

April 2005). There is considerable

concern that climate change threatens

global water resource availability. The

effects of natural climate variability and

the threat of anthropogenic change are

particularly felt in less developed coun-

tries (LDCs) where floods and droughts

result in substantial loss of life and

livelihood. Coupled with the marked

decline in observational networks, there

is a critical need for reliable information

relevant to hazard mitigation and water

resource management.

This symposium will address the

usefulness of hydrological science in

helping decision makers cope with the

hydrological impacts of climate varia-

bility and change. Contributions were

solicited on the following topics with an

emphasis on (but not limited to) LDCs.

– Potential hydrological impacts of

future climate including the role of

natural variability and anthropogenic

climate change.

– Analysis of historic hydro-

climatological variability of relevant

regions, including model simulations,

data and knowledge “on the ground”.

– Problems in translating coupled land-

atmosphere model outputs to

hydrological variables at point, basin

and regional scales.

– Hydro-climatically relevant decision-

making, risk assessment and

mitigation/adaptation strategies using

uncertain model predictions of water

resources and hydrological extremes.

Almost 140 abstracts were submitted for

consideration in this symposium. This

was such a huge number that it was

decided to extend the symposium from

two to three days and to publish two

IAHS Red Books instead of one as

initially planned.

Future We anticipate considerable discussion

regarding the future activities of the

commission to take place at the

upcoming symposium in Brazil. Since

the commission’s primary goal is to

promote the use of information

generated by coupled land–atmosphere

models (and remotely sensed data sets)

for water resources and emergency

management applications in LDCs, it is

important that the scientists and

decision makers in such regions

collaborate with western scientists to

guide the testing and implementation of

cost-effective mechanisms for improved

water resources decision making. Given

the considerable interest displayed in the

forthcoming symposium, we plan to

explore the possible formation of

regional chapters of the commission

with particular foci on areas such as

South America, central America, Africa,

southeast Asia and eastern Asia, etc.

The Turkish General Directorate of State Hydraulic Works (DSI), the main organization widely representing the hydrological community in Turkey, has enlarged its existing representative res-ponsibilities, and is actively engaged in coordinating all hydrology-related organizations in the private and the public sectors, newly emerging institut-ions, establishments and universities. The main hydrology-related organiza-tions are the General Directorates of the State Hydraulic Works, Electrical Power Resources Survey and Develop-ment Administration, State Meteoro-logical Affairs, Rural Services, and the Middle East Technical University, Hacettepe University, Gazi University, Istanbul Technical University, and 9 Eylul University, all of which are major contributing members of the Turkish hydrological community. For this purpose, a newly established unit, the Office of International Hydro-logical Affairs, has been established under the auspices of the Investigation and Planning Department, DSI, to achieve coordination efficiently. The Unit serves as a focal point for various

international hydrological projects and programmes, which are important for the improvement of operational hydro-logical works and scientific studies in Turkey, such as the IAHS, UNESCO International Hydrological Program (IHP), WMO Operational Hydrology Prog-ramme and Commission of Hydrology (CHy), Hydrological Advisory and Hydrological Operational Multi-purpose System (HOMS). It also covers the provision of advice to management on all related research, training, educatio-nal and practical matters in hydrology and so DSI has more ability in shaping national water resources policies. All information relating to hydrology and IAHS is distributed to the hydro-logical community using the hydrology e-group: [email protected]

There are about 370 members, many from the Turkish National Hydrological Commission (TNHC). News relating to hydrological issues which are con-sidered in the framework of inter-national hydrological activities, and news from reorganized study groups (sub-commissions) inside TNHC are issued in a weekly newsletter. The e-

group also serves as a forum environ-ment, which has been found quite effective in informing and in discussing hydrological issues. With regard to the hydrological archive, there have been some concrete improvements; all available hydro-logical documents, including IAHS pub-lications, are stored in an archive, and introduced to the hydrological comm-unity using the Internet and are available in a library. To conclude, the institutional harmo-nization of international hydrological activities can definitely be beneficial in the long run, especially in developing countries where decision making in a coordinated environment is considered much more important with respect to the institutional and scientific develop-ment at the national level.

BALWOIS 2004, MainrecommendationsThe main recommendations of the

Balkan Water Observation and Informa-

tion Systems conference were:

(i) To build a community of water

sciences in Balkan countries.

(ii) To attract/motivate/invite the young

generation of scientists to work in

the field of integrated and sustain-

able water resources management in

a context of climate and environment

changes, e.g. by organizing courses,

training, PhD and postdoctoral studies.

(iii) To push the research institutions,

scientists and funding organizations

from developed countries to help/

assist/support the scientific organiz-

ations and scientists in countries

with economies in transition in the

area concerned (otherwise the gap

between them will increase further).

(iv) To establish/improve contacts with

NGOs, stake-holders and media (e.g.

TV, radio, newspapers) connecting

science to practice and society.

(v) To promote international sharing

and dissemination of hydrometeor-

ological data and all water related

information and the implementation

of common regional databases.

(vi) To improve the search for sponsors

and donors, international and

national funds to support such net-

working activities.

(vii) To organize regular research con-

ferences and workshops, such as

BALWOIS 2004, where:

– recent scientific results and activities

in the fields of water cycle, water

resources management and

protection linked with climatic and

environmental changes and

anthropogenic pressures will be

presented and discussed;

– research/development joint projects

will be prepared for submission e.g.

under the EC 6FP or other national/

international funding organizations;

– exchanges with NGOs, stakeholders

and general public will be improved.

River/CatchmentDynamics: Natural Processes and Human Impacts International Conference, Solsona, 15–20 May 2004

This conference was another in the long

list resulting from over 18 years of

activity by IAHS’s International Comm-

ission on Continental Erosion (ICCE). It

explored issues concerning river and

catchment processes, with special refer-

ence to Mediterranean environments. A

particular focus was on the linkages

between human impacts, catchments

and river dynamics, as a basis for

environmental management.

The conference took place on the

occasion of the retirement of Maria Sala.

The career of Professor Maria Sala

started more than 30 years ago at the

Universitat de Barcelona, where she is

currently still working as a Professor in

the Department of Geography. She has a

BA in Geography (Physical Land-

scapes) and a PhD in Geography

(Fluvial Geomorphology) from the

same university. While leading the

Harmonizing of international hydrological activities at the national scale: Turkish experience

Reports from conferences:


Mediterranean Environment Research

Group, her research interests lie in the

fields of fluvial geomorphology, soil

and slope erosion, and catchment

hydrology and water quality.

Work in these fields has mainly been

undertaken in the Catalan Coastal

Ranges although, through cooperative

work, she has conducted research in the

UK, German Alps, Tunisia, Portugal,

Argentina and Mexico. Her fundamental

research is applied to environmental

problems, mainly increased runoff and

flooding as a result of expanding urban

land use and forest fires. Her current

research includes hydrology and

sediment dynamics in Mediterranean

mountain catchments, effects of

prescribed burning on increased runoff

and erosion, morphological changes and

sediment transport in the bed of a Medi-

terranean river, fluvial transport of

suspended material: sources, routing,

storage and yield.

Her most important publications have

been published in Catena, Zeitschrift für Geomorphologie, Geomorphology,

Journal of Sedimentary Research, Earth Surface Processes and Landforms,

and Geografiska Annaler, and co-

authored with Ramon J. Batalla, Peter

Ergenzinger, Celso Garcia, Moshe Inbar,

and Jonathan B. Laronne, amongst

others. Together with Arthur J. Conacher

she edited the book Land Degradation in Mediterranean Environments of the World: Nature and Extent, Causes and Solutions (1998), published by

Wiley.

Maria Sala was the chair of the

Commission on Land Degradation and

Desertification (COMLAND) of the

International Geographic Union from

1996 to 2000, and she is still a member

of the Steering Committee of the

commission that co-organized the

conference. Other organizers were the

universities of Lleida, the Balearic

Islands, Barcelona, and the Forestry

Technology Centre of Catalonia.

The conference in Solsona included

excursions to sites of geomorphological

interest in Catalonia, where Maria Sala

and her former students have been

undertaking research during the last

decade.

Almost 100 participants discussed

the following topics and themes:

sediment sources and transfer to the

fluvial system, fluvial processes and

sediment transport, erosion processes

and land degradation in drainage basins,

human impacts on Mediterranean

fluvial environments, water and

sediment management. The issues

addressed concentrated around the last

two decades of progress in process

geomorphology and future prospects,

understanding anthropological impacts

on the environment causing land degra-

dation, present-day diagnosis and future

key strategies for environmental

management in Mediterranean river

catchments, and linking process

geomorphology with other earth and

environmental science disciplines.

The conference took place in a

pleasing and pleasant atmosphere. The

weather was beautifully sunny and

warm; the venue overlooked the village

of Solsona against a backdrop of the

snow-capped southern outliers of the

Pyrenees. What a pity we could not go

to those summits! It cannot be true that

most catchment dynamics are to be

found in the riverbed instead of near

mountain vistas. The meeting was

remarkably well organized, with details

such as amplified loudspeakers taken

into the field and lunch served along a

river in the woods. The organizers took

care of all the small but important

things. Compliments go to Ramon J.

Batalla (University of Lleida/Forestry

Institute of Catalonia) and his team

(including co-organizers Celso Garcia,

Moshe Inbar and Rosa Ricart) for taking

care of all the pesky details and

participants with last-minute wishes and

requests! An IAHS Red Book with the

conference papers the will be published

next year.

To come to an end, I would like to

use the opportunity to bring to your

attention a recent publication from

UNESCO’s International Hydrological

Programme (IHP). Number 60 in the

series Technical Documents in Hydro-

logy is Modelling erosion, sediment transport and sediment yield. The 264-

page publication has been edited by

Wolfgang Summer and Desmond E.

Walling, demonstrating the state-of-the-

art in this area. The report can be

downloaded free of charge (!) from

UNESCO’s website:

http://unesdoc.unesco.org/images/0012/

001278/127848e.pdf (3.64 Mbyte).

Paper copies, also free of charge,

may be requested from me, or directly

from UNESCO in Paris, [email protected].

My personal experience is that

reports will be delivered promptly—an

excellent service from the IHP

Documentation Centre!

Sediment Transfer Through the Fluvial System (ICCE)

International Symposium, Moscow, Russia, 2–6 August 2004

About 90 researchers from 26 countries

took part in the International Sym-

posium on Sediment Transfer Through the Fluvial System hosted by the Faculty

of Geography of the Moscow State

University. Co-sponsored by UNESCO,

the Symposium represented a

contribution to the International

Sedimentation Initiative (ISI) of the

UNESCO International Hydrological

Programme (IHP VI). Its major object-

ive was to share knowledge, to

exchange views and to determine the

most promising and problematic

research areas for researchers from

various scientific backgrounds: hydro-

logists, geomorphologists, environ-

mental scientists and others. It is

necessary to link separated data into a

comprehensive system to answer

questions of how, when, where and at

what magnitude fluvial processes will

react to changes in natural or anthro-

pogenic conditions. Contributions to the

Symposium covered all scales of fluvial

sedimentary systems, from hillslopes

and small first-order catchments to large

river basins and their outlets into the

oceans.

The 55 oral papers presented during

the Symposium were separated into five

sessions covering various scales and

aspects of fluvial sediment transport,

associated geomorphic and hydrological

processes, modelling approaches and

environmental effects such as particle-

bound pollutant redistribution (Co-

convenors names in brackets):

1. Sediment redistribution within

small catchments in different environ-

ments: temporal and spatial interaction

of various geomorphic processes; quanti-

fication of sediment delivery ratios,

sources and sinks (Dr P. Porto, Italy,

and Dr A. Panin, Russia).

2. Interaction of rivers and river

catchments in undisturbed and

intensively cultivated basins: deter-

mination and comparison of natural and

human-induced trends in small fluvial

systems development; linkages and

mutual responses between hillslopes

and channel networks (Dr P. Wallbrink,

Australia, and Dr V. Golosov, Russia).

3. Large river system functioning:

channel and flood-plain deformations


(Prof. D. E. Walling, UK, and Prof.

R. Chalov, Russia).

4. Modelling of erosional and dep-

ositional processes (Dr H. Middelkoop,

The Netherlands, and Prof. G. Larionov,

Russia).

5. Implications for nutrient and

contaminant transfer: sediment-bound

matter tracing through fluvial systems

(Dr I. Droppo, Canada, and Dr A.

Horowitz, USA).

The Symposium Proceedings were pre-

published as IAHS Red Book 288

which contains 61 reviewed papers

arranged according to the topics of the

five sessions described above (see p. 5).

In addition to oral presentations, a

special time and place for poster pres-

entations was allocated during the

Symposium, and 36 posters from 10

countries were presented. Short comm-

unications of these posters have been

published by the Moscow University

Press as a separate volume in both

English and Russian.

During the Symposium, a one-day

field trip was held to the Faculty of

Geography of the Moscow State Univ-

ersity field training and research station

“Satino”, located some 100 km to the

southwest of Moscow. It included two

separate scientific parts: “Monitoring of

sediment transfer through the cultivated

hillslope–gully–river channel system”

and “Fluvial landform morphology and

development in the Holocene: the

Protva River flood plain, natural and

anthropogenic gullies”. The scientific

part of the field trip was followed by an

excursion to the historical city of

Borovsk and the Pafnut’ev-Borovskiy

monastery located nearby. A special

scientific guide-booklet with detailed

information about the research station,

both scientific excursions, and the

history of the city of Borovsk and the

surrounding area, was distributed to the

participants before the excursion.

After the official closing of the

Symposium, 18 foreign participants

took part in the post-symposium tour. It

was a five-day bus excursion through a

number of cities of the Golden Ring of

Russia, including Sergiev Posad,

Pereslavl-Zalesskiy, Rostov, Uglich,

Yaroslavl, Suzdal and Vladimir, with

many scientific, historical and cultural

sights. It also included a visit to the city

of Rybinsk, with a one-day boat

excursion on the Rybinsk Reservoir on

the Volga River.

DistributedHydrological Modelling using Geospatial Data and Tools CNR-MIT Summer Course University of Rome “La Sapienza” Rome, Italy, 21–25 June 2004

The Massachusetts Institute of Tech-

nology (MIT) and the Consiglio

Nazionale delle Ricerche (CNR) of Italy

have established a collaborative agree-

ment to conduct bilateral investigations

on climate change and hydrogeological

disasters, with an emphasis on Medi-

terranean regions. Recently celebrating

its ten year anniversary (http://smd.src.cnr.it/Irpi/CNR-MIT/index.html), the

CNR-MIT Agreement focuses on the

potential impact of climatic changes on

floods, landslides and droughts. An

important element in the collaboration

between MIT and CNR has been the

offering of short summer courses in

Italy by MIT-affiliated faculty. Thus far,

a total of 15 courses have been held on

topics ranging from hydrological

predictability, remote sensing and data

assimilation to debris flow hazards,

landslides and landscape evolution.

Most recently, a five-day summer

course was held in Rome, to address the

topics of assessing extreme hydrological

events using geospatial data and models.

Organized by the CNR Research

Institute for Geo-Hydrological Protect-

ion (IRPI) and the University of Rome

“La Sapienza”, the summer course was

attended by 65 participants representing

over 12 universities and research

institutes in Italy. The short summer

course focused on the theory, concepts

and applications of distributed hydro-

logical modelling through a series of

lectures and “hands-on” workshops with

GIS-based data, tools and models. In

conjunction with lectures on flooding

hazards, hydrological processes, met-

eorological forcing, terrain represent-

ation and modelling techniques, the

workshops provided the practical skills

for conducting simulations using geo-

spatial data. Participants were then

guided through the application of a

distributed model developed at MIT

known as the TIN-based Real-time

Integrated Basin Simulator. A continued

interest in the distributed hydrological

simulation has been expressed by a

subset of the participants, suggesting the

potential for a peer-reviewed publ-

ication in the near future. The CNR-

MIT Summer School 2004 on

Distributed Hydrologic Modelling using

Geospatial Data and Tools was organ-

ized by Enrique Vivoni (New Mexico

Institute of Mining and Technology),

Salvatore Grimaldi (National Research

Council, Research Institute for Geo-

Hydrological Protection), Fernando Nardi,

Lucio Ubertini (University of Rome “La

Sapienza”), Valeri Ivanov, Rafael Bras,

(Massachusetts Institute of Technology),

and Fabio Castelli (University of

Florence). Materials from the summer

course are available at

Water in The Netherlands – revised edition published

“The key to understanding the geography and institutions of the Netherlands and Dutch behaviour can be found in the country’s flood defence and water management”, according to the Dutch Vice Minister of Transport, Public Works and Water Management, Mrs Schultz van Haegen. It is for this reason that she recently welcomed a revised edition of Water in The Netherlands. Of course, the Dutch presidency of the EU during the second half of the year 2004 was also a good reason to embrace the timely publication. In its 132 pages the booklet provides an overview of human interventions in natural conditions over time and space and their impact on Dutch society, as well as information about the challenges for water management in the future. Full colour illustrations make it an attractive book.

The publication describes the hydrological events that occurred over centuries and the corresponding experience of the Dutch in conquering water. Geography, climate and hydrology are described, followed by an historical overview of the man-made environment in the Low Lands near the sea. Special attention is paid to the mostly negative impact of the development on water quality. Water management is illustrated in the international context, as well as on a national scale, including recent developments such as sustainable development of water systems. This concept is based on the philosophy that three elements need to be taken into account when managing a water system: the natural system, interests and functions, and the legal and administrative framework. The latter is also described in a separate chapter. Of course, the European Union water policy and Water Framework Directive are also covered by a chapter of their own. Three chapters on international cooperation, activities abroad, science, education and research form the closing of the book. The original publication has undergone several stages of revision during which the Commit-tees of the IAHS and the National Committee for UNESCO’s International Hydrological Programme and the Hydrology and Water Resources Programme of WMO contributed as well. Pieter Huisman updated the present edition. As with the previous edition the book is published under the umbrella of the Netherlands Hydrological Society (NHV).

IN MEMORIAM

Professor Zivko Skoklevski, one of the most active hydrologists in the Republic of Macedonia died in

January 2004He was born in 1937, in the village of

Dambeni, Northern Greece (former

Aegean Macedonia). In 1948 he moved

to Czechoslovakia, where in 1955 he

completed high school in Brno. In 1960

he graduated from the Faculty of Civil

Engineering Hydraulic Department,

Prague.

In 1966 he worked as designer in the

Regional Water Resources Institute in

Pilsen, but later that year returned to the

Republic of Macedonia, where he

started to work in the Water Develop-

ment Institute. In 1969 he entered the

Faculty of Civil Engineering in Skopje

as an assistant, and he was elected to

assistant professor for River Training in

1977. In 1979 he completed his PhD

thesis in Stochastic Hydrology. He was

elected as professor for the topics:

Hydraulics, Hydrology, River Training

and Waterways and Ports. He also had

completed international master studies

in Delft, the Netherlands in 1971/72.

During his work at the Faculty in

Skopje he published two textbooks for

the regular students and two manuals

for post-graduate students. In cooper-

ation with Professor Blagoja Todorovski

he published the monograph: Intensive Precipitation in Macedonia, while after

his retirement he published three more

monographs about the River Vardar and

Dojran Lake.

In the period from 1984 to 1986,

through the programme for International

Scientific-Technical Cooperation of the

Republic of Macedonia, he lectured at

the Faculty of Civil Engineering in Dar-

es-Salam, Tanzania.

Professor Skoklevski had significant

experience as researcher and designer in

many areas of water resources manage-

ment and hydro engineering, which was

proved through his wide scientific and

application activity. He made, alone and

in cooperation with other colleagues, a

number of feasibility studies and final

designs, studies and expertises. He was

actively involved during all his prof-

essional life in solving problems in

water resources management in

Macedonia and he worked in several

professional and scientific associations.

Professor Skoklevski published many

scientific and expert papers in scientific

journals, international and national

conferences and symposium proceedings.

With the death of Professor

Skoklevski, the Faculty of Civil

Engineering has lost a respected and

highly appreciated colleague, an extra-

ordinary pedagogue, a dear collaborator

and a very good friend. His retirement,

several years ago, was not the end of his

professional work. He devoted himself

with even more strength to writing and

designing, and he has left to us his

experience. For this life’s determination

Macedonian hydrologists are forever

grateful.

HYDROLOGY:A question of balance

by J. V. Sutcliffe IAHS Special Publication 7

ISBN 1-901502-77-5 200 + xviii pages Paperback November 2004 Price £30.00

Hydrology: A Question of Balance is a unique hydrology text. It brings hydrological analysis to life by means of examples in which the author has been involved: numerous practical problems that had to be tackled (often despite limited data, resources and time) are described and the methods that were used to find a solution are explained. The application of a water balance is an essential component in solving these applied problems. John Sutcliffe offers the experience of a hydrologist with extraordinary practical expertise, assembled in areas with different climates, topographies, levels of development, and cultures. Projects in many countries, including Sudan, Iran, Senegal, Botswana, India, Sri Lanka, New Zealand, Bosnia, Poland and the UK, are detailed to illustrate how hydrologists can, and need to, use all the available information to understand the hydrological context of their studies. Practising hydrologists and engineers, as well as students, will learn from this volume which complements standard hydrology textbooks.
