Abstract

Control of sedimentation in reservoirs of DAMs is considered to be one of the most important issues in exploitation of DAMs and increasing their useful life.Reservoirs act as traps for sediments and prevent transport of sediments to the river. The deposited sediments will decrease the capacity of the reservoirs so that they cannot be in use any more. Various methods are discussed in this study to remove a part of the deposited sediments, but Flushing is the method, which has been used extensively in many projects all over the world due to the fact that the flow energy is utilized and there is no need to employ an external source of energy. In this study a one-dimensional model is developed in which continuity equation of sediment is solved by the finite difference method using the Cranck-Nickolson method. The developed model is capable to compute the variation of the reservoir bed with time. Also, the accumulated flushed sediment volume and reservoir water volume are calculated at different time steps. The Fotran language used for programming of the model was based on the results obtained from physical models employed by several investigators.And comparison was done with HEC-6 Model. The verification of the model was done using data from the natural reservoir of Dashidaira DAM in Japan. The results were compared with the actual measurements. A good agrement was observed between them but the Hec-6 doesn’t show a good verification.
