terjadi ditentukan Formzhal Number .

= + +
=12.67 + 6.7
12.02 + 9.56= 0.898
Nilai bilangan Formzhal pada area
Suralaya adalah 0.898 yang berada diantara 0.25 sampai 1.5. Oleh karena itu
pasang surut pada area ini bertipe mixed,
mainly semi diurnal . Dalam satu hari
pasang surut terjadi dengan pola terjadi
dua kali air pasang dan dua kali air surut,
tetapi tinggi dan periodenya berbeda.
Berikut merupakan elevasi muka air
selama 72 jam yang diambil dari
potongan sketsa plot ketinggian muka air
dari DISHIDROS TNI-AL selama satu
bulan yang menunjukkan tipe pasang
surut campuran condong ke diurnal di

6. Peramalan elevasi pasang surut selama 18.6 tahun
Dengan program ERGRAM didapatkan ramalan elevasi muka air selama 18.6 tahun (163.272
jam).
(18 ℎ 365 ℎ + 4 31 ℎ + 2 30 ℎ
+ 1 28 ℎ + 21 ℎ) 24 = 163.272 Berikut hasil ramalan selama 15 hari yang dicuplik dari hasil pengolahan data oleh program
