Optimal Allocation of Monthly Water Withdrawals in Reservoir Systems

In this study, a water balance equation was derived and theperformance of a project was analyzed. The water balancecomponents were modeled without calibration, and compared withmeasured data, whenever possible. A reservoir simulation modelwas develop and the model storage capacities were compared withthe observed storage capacities satisfactorily. An optimizationmodel was developed to solve the water resources of a largeproject in a computationally satisfactory manner. The optimalreservoir storage, optimal irrigation demand, and optimalreservoir release were computed. The optimal mean (1987–1997)model total water requirements for the dry and wet seasons werealso computed and the optimal contributions by rainfall,reservoir, uncontrolled river flow, and recycled water weredetermined. The mean annual optimal water withdrawals from thereservoir systems were found to be 1223 MCM (Million cubicmeters). The optimal mean model total water requirements werecompared with other authors computed values for the same and asignificant water savings was achieved. Copyright Kluwer Academic Publishers 2001
