| 摘 要： | 对平原地区感潮河流的水质进行了数值模拟，通过建立1D水动力学和水质的联合模型，分析感潮河流的水位和水质浓度随潮汐变化情况。水动力学模型采用Preismann隐格式离散，水质模型对流项采用迎风格式。模型结果较好．可以用于预测感潮河流的水质变化情况。

| Abstract: | This paper models water quality for tidal river with numerical methods. By linking one dimensional hydrodynamic and water quality model, analyze the change of water level and water quality concentration as tidal change. Using Preissrnann implicit form discretize hydrodynamic model, and upwind form applied to the advection of water quality model, The results can be applied to predict water quality change in tidal river in plain region. |
