Optimization of Released Water from the Dez Dam for Supply of Water Demands in the Downstream of Dam

摘要

For supplying of water demands in the downstream of dams, optimization of released water from reservoir of dam is necessary. Released water from reservoir is related to discharge of inflow to reservoir, volume of evaporation from reservoir and storage of reservoir. Water demands are includes of drinkable water and agricultural water demand. If released water from reservoir is less than water demands in a month, this month will be a defeat. After a defeat, reservoir must return to normal condition in order to supply of water demands in next months. For minimize the number of defeats and maximize return ability of reservoir to normal condition, a suitable method must be applied for optimization of volume of released water from reservoir. In this research, two optimum methods (SDP method and GA method) were applied for minimize the number of defeats and maximize return ability of reservoir to normal condition. For this purpose, reservoir of the Dez dam was considered in this research. The Dez dam locates in the south-west of Iran on the Dez River. At the end, it is observed that GA method can minimize the number of defeats and maximize return ability of reservoir to normal condition better than SDP method. But SDP method can minimize damage function better than GA method.
