建立水库坝区平面二维水流泥沙数学模型，考虑了悬移质非均匀、非饱和输沙特性，采用正交曲线坐标拟合复杂边界、ＳＩＭＰＬＥＣ程式离散求解及动边界技术．用该模型对白沙水库流场和河床变形进行了数值验证，计算了典型年条件下，水库取水口附近流场和河床局部形态．结果表明坝前取水口漏斗基本保持稳定状态．
The mathematical model of two-dimensional flow and sediment in the reservoir dam area is established. Considering the characteristics of non-uniform and unsaturated sediment transport, the orthogonal curve coordinates are used to fit the complex boundary and the SIMPLEC program is discretized and the dynamic boundary technique is used. The model was used to verify the flow field and riverbed deformation in Baisha reservoir. The flow field and riverbed near the reservoir water intake were calculated under the typical conditions. The results showed that the funnel at the front of the dam remained basically stable.
