- Abstract
Through the sediment model experiment of movable bed in dam area, the sediment discharge issue of Kalabeili Reservoir was studied. The flow pattern in front of the dam, the change of flow velocity along the dam and the shape of sand funnel were observed during the operation of reservoir sediment discharge. The effect of reservoir sediment discharge under different water levels and different working conditions of sand discharge tunnel was analyzed. The possibility of restoring part of the reservoir capacity was discussed through the open discharge test. The studies have shown that water depth and sediment discharge are important factors affecting reservoir sediment discharge, and the efficiency of reducing water level and sediment discharge is higher under the same sediment discharge. The reservoir should seize the favorable opportunity and flexibly use various ways to flush sand according to the upstream water and sediment conditions and the operation of the power station and the sedimentation elevation in front of the flushing tunnel.
