基于水流泥沙数学模型的西洋河水库泥沙淤积模拟分析

Simulation analysis of sediment deposition in xiyanghe reservoir based on flow and sediment mathematical model

为预测西洋河水库的冲淤演变情况,利用库区地形地质资料建立二维水流运动及泥沙输移数学模型,采用该模型对不同工况下西洋河水库的水流、泥沙运动进行数值模拟,从而得到库区水流运动基本规律及库区的淤积冲刷分布,为库区清淤治理及运行管理提供参考依据。

In order to predict the erosion and deposition of the Xiyanghe reservoir,a two-dimensional mathematical model of water flow and sediment transport is established based on the hydrographic and topographic data of the reservoir area,the model is used to simulate the flow and sediment movement of Xiyanghe Reservoir under different working conditions,thus the basic law of flow movement and the distribution of silting and scouring in the reservoir area are obtained,it provides reference basis for dredging work and operation management in reservoir area.
