Reservoirs are designed to provide the balance between
the flow brought by the river which is high variable in time and volume of
water. The storage required on a river to meet a specific demand depends
basically on three factors; the magnitude and the variability of the river, the
size of the demand and the degree of reliability of this demand being met.
Several procedures have been proposed to estimate storage requirements.
Critical period methods are those in which required reservoir capacity is
equated to the difference between the water released from an initially full
reservoir and the inflows for periods of low flow. In the presented study
reservoir capacity-yield-reliability relationships are investigated for a
single reservoir named Sami Soydam
Sandalcık Dam. For this purpose, six design techniques (Mass Curve, Residual
Mass Curve, Moran Probability Matrix Method, Hardison's method and Minimum flow
approach) are used in determining reservoir capacity, monthly and annual mean
flow data observed for a period between 1962-2013, of EIE-811 Suçatı Flow
Gauging Station on Dalaman River in West Mediterranean Basin in Turkey are used
as case study. For 0% probability of failure,
the highest reservoir capacity resulted
for methods Mass Curve, Residual Mass Curve and Minimum flow approach at the
range between 814.22 to 852.74*106 m3 for draft equal 60%
and at the range between 2043.4 to 2145.74*106 m3 for
draft equal 80% by using the monthly data. On the other hand when high value of
probability of failure (5% and 10%) are used for estimation, the reservoir
capacity values were resulted at the range between 612.36 to 1154.74*106
m3 for draft equal 60% and at the range between 1443.42 to
2165.13*106 m3 for draft equal 80% for Hardison's method.
By using Moran Probability Matrix method, the reservoir capacity resulted 1280*106 m3 and
the interval was divided to 140*106 m3 for annual data 52
years.
