| 摘 要： | 基于河道几何特征以及污染物对流、湍动扩散和混合稀释的不同机制,构建起模拟上海青浦城区西北片河网内污染物浓度时空分布的二维数学模型;采用两种不同的实际调水工况(先排后引和边引边排),对所建模型进行了验证计算.结果表明,河网内各取样点的污染物浓度实测值与计算值都基本一致.从而证明了所建模型具有工程适用性,可用于模拟上海青浦城区西北片的河网水质调节过程.

| Abstract: | Based on the principles of convection,turbulent diffusion and mixing of pollutants,a two dimensional mathematical model was developed for evaluating the temporal-spatial distribution of pollutants in a river network located in the northwest part of Shanghai's Qingpu urban area.Two water transfer cases for water quality improvement were simulated with the model.The computed pollutant concentrations at five different sampling points agree well with the measured data and validate therefore the model. |

| Keywords: | river network water quality improvement mathematical model numerical simulation |
