摘　　要：通过建立一种立面二维模型 ,考虑自由水面的变化 ,采用全显式的有限体积法模拟了河道流动的水温及悬浮污染物质分布 .该模型适用于大尺度水域中较长期的流动、水温及悬浮物质迁移问题 .通过优化取水口位置高程将水体中污染物质残存总量控制到最少 ,对水库实际流动、水温、悬浮物质分布的模拟结果与实际观测符合良好 .A model for predicting the thermal stratified flow and turbidity transportation in the vertical section of a river is established. Since the scheme is explicit for velocity components, pressure and scalar quantities, the model is efficiency and able to simulate long period transportation process of suspending materials in reservoirs and rivers. The model can be used to forecast and control of pollution. The validity of this model is verified by in site observation data.
