Evaluation of sedimentation and flushing by mathematical model in reservoirs of the successive Dez stream dams in Iran

The successive Dez stream dams (the Dez 1 dam, the Dez 2 dam & the Dez 3 dam) will be constructed on the Dez River for production of electrical energy. Because of the heights of these dams are low, it is required to control sedimentation in the corresponding reservoirs. Sedimentation will capture the volume of reservoirs very rapidly. In this paper, a method of sediment management and mathematical simulation for flushing from reservoir of dams is explained. Lack of sediment data and inaccuracy of acceptable sediment data are considered. Sensitivity analysis of the mathematical model is evaluated for variation of sediment parameters. This paper shows that flushing can retrieve beneficial storage of reservoirs.
