河网数学模型在水环境治理中的应用

Application of River Network Numerical Model to the Treatment of Water Environment

采用圣维南方程组,并利用节点水位控制法,建立河网一维水流数学模型。并以张家港城区河网为对象,应用该模型进行了水环境治理工程对策的研究。根据数值模拟结果,提出引水排污的具体方案,为水环境治理工程提供了设计依据。该河网数学模型同样适用于其他沿江城市河网的水环境治理工程对策的研究。

Based on the Saint-venant equations,a current numerical model for river networks is established by using the node control method for water level.It is applied to the study of water environment treatment in the rivers of Zhangjiagang City.According to the results of the numerical model,a workable scheme of diversion works for water environment treatment is presented and it serves as a basis for the design of water environment treatment projects.The river network numerical model can also be applied to the study of water environment treatment in other rivers along the Yangtze River.
