Abstract

Abstract.    In this study, the numerical simulation of the flow hydraulic and sedimentation in an intake with rectangular channel is performed using SSIIM2 model. At the first, the distribution of the profiles of the flow velocity near the water surface, the size of the flow separation zone in the intake and inflow sediment to the intake at various sections of the main channel and the intake for a constant inflow with different turbulence models were simulated in 3D state and compared with the experimental results of other researchers and there were a good agreement between them. Considering the obtained good results, in order to study the flow pattern and the sedimentation in the pumping station inlet, the numerical analysis of the parameters affecting the hydraulic field and sedimentation in front of the inlet of a real pumping station is performed.
