| 摘 要： | 本文从紊动扩散理论出发根据浅水湖泊紊流扰动特性，推导出包含底泥污染的水质控制方程，并与浅水方程耦合，建立相应的平面二维水流-水质-底泥污染的数值模型。模型在有限体积法框架下应用黎曼近似解求得耦合方程的数值解。并以玄武湖为例进行模型验证。结果表明，数值解与实测值较吻合，证明预测结果可信。

| Abstract: | The control equation of water quality considering the bed sediment pollutant is deduced according to the characteristics of turbulent disturbance. The equation is coupled with shallow flow equation to establish the depth averaged 2-D plane flow-water quality-sediment pollutant transport model. Under the framework of finite volume method, the Riemann approximate solver is applied to obtain the numerical solution of the equation. The model is used to simulate the total phosphorus transport in the Xuanwu Lake, Nanjing. The result is in good agreement with observation data. |
