摘　　要：建立了具有连续急流弯道河流平面水流、泥沙数学模型 ,并采用有限差分法对方程进行离散求解。运用该模型对山西省阳泉市桃河治理河段的水流泥沙情况进行计算 ,得到的数值模拟结果与模型试验结果基本相符 。A two\|dimensional flow and sediment model is proposed for channel with continuous curves,and is solved by the finite difference method.It can be used to calculate the flow and sediment scouring and deposition in the Taohe River in Yangquan city,Shanxi Province,China.The results show the model is applicable for the design of hydraulic engineering.
