Abstract

Dams construction are high cost projects, and therefore, optimal using of reservoir storages behind dams is an important task in water resources management. In last decades, various optimization techniques have been used for reservoir operation. Among the new methods, Genetic Algorithm (GA) and wavelet transform (WT) have been widely used in recent years. In this study, GA as well as combination of GA and four WT (Coif5, Haar, Db10 and Sym4) has been investigated in optimal operation of Reservoir storages. Using these techniques operation of the multipurpose Vanyar dam reservoir in Tabriz, Iran has been optimized. Results were compared using total monthly square deviation (TSD) of release and demand. The best results were obtained for the case of combined GA and WT sym-4 with least TSD equal to 17.453 and reliability of 84%.
