Study on the Rules of Sedimentation in Ningxia Shuidonggou Reservoir

Abstract:

In order to predict the sedimentation deposition in the Shuidonggou reservoir in next few years, the flow in this reservoir is studied using the two dimensional (2D) hydraulic mathematical model. The governing equations of the model are discredited with finite volume method (FVM) on unstructured grids, and the 2-D flow movement are simulated under several different conditions. The results showed that: when the amount of the water inflow and the water drawn unchanged, as the water level drops, water flow velocity increases in the reservoir; at high water level (1179 m), the left bank of the south side of the intake eroded; at low water level (1174.4m), north and south sides of the mainstream of water have a recirculation zone; when the water level is constant, with the increase of the amount of water, the recirculation zone on the right side of the intake became smaller and close to the water intake.
