    取水前池含沙量较大时,需要考虑前池中的泥沙淤积分布情况,以便于确定抽水泵运行模式及装配清淤设备.本文应用正交曲线坐标系下的水深平均二维数学模型对前池流态、泥沙淤积分布进行了数值模拟,结果与理论分析、相关研究结论一致.

    In the paper, the horizontal 2-D flow and sediment mathematical model under orthogonal curvilinear coordinates is used to simulate the sediment deposition in the water intake forebay. The model can be used to forecast the sedimentation and has a practical application value to the operation of the forebay.
