| Summary: | Reservoirs are designed to provide the balance betweenthe flow brought by the river which is high variable in time and volume ofwater. The storage required on a river to meet a specific demand dependsbasically on three factors; the magnitude and the variability of the river, thesize 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 isequated to the difference between the water released from an initially fullreservoir and the inflows for periods of low flow. In the presented studyreservoir capacity-yield-reliability relationships are investigated for asingle reservoir named Sami SoydamSandalcık Dam. For this purpose, six design techniques (Mass Curve, ResidualMass Curve, Moran Probability Matrix Method, Hardison's method and Minimum flowapproach) are used in determining reservoir capacity, monthly and annual meanflow data observed for a period between 1962-2013, of EIE-811 Suçatı FlowGauging Station on Dalaman River in West Mediterranean Basin in Turkey are usedas case study. For 0% probability of failure,the highest reservoir capacity resultedfor methods Mass Curve, Residual Mass Curve and Minimum flow approach at therange between 814.22 to 852.74*106 m3 for draft equal 60%and at the range between 2043.4 to 2145.74*106 m3 fordraft equal 80% by using the monthly data. On the other hand when high value ofprobability of failure (5% and 10%) are used for estimation, the reservoircapacity values were resulted at the range between 612.36 to 1154.74*106m3 for draft equal 60% and at the range between 1443.42 to2165.13*106 m3 for draft equal 80% for Hardison's method.By using Moran Probability Matrix method, the reservoir capacity resulted 1280*106 m3 andthe interval was divided to 140*106 m3 for annual data 52years. |
