基于SWMM耦合HEC-RAS的人工建设水网防洪排涝模拟研究OA
Research on Flood Control and Drainage Simulation of Artificial Water Networks Based on SWMM Coupled with HEC-RAS
对新建城区的水文、水动力过程进行准确模拟分析是人工水网规划建设及新建城区内涝防治的关键.应用SWMM分布式水文模型耦合HEC-RAS二维水动力SWE-ELW模型,对安徽省阜阳市城南水网进行模型模拟及防洪排涝分析.结果表明,SWMM模型中计算参数更多,排涝模数随汇水分区面积增大而减小,且与规划泵站排涝模数接近,计算结果更为合理.城南水网排涝标准30年一遇工况下,城南水网水系汛期最高水位为27.89 m,满足排涝方案要求;各闸门过流流量与其河道底宽成…查看全部>>
Accurate simulation and analysis of hydrology and hydraulic processes in newly constructed urban areas are crucial for the planning and construction of artificial water networks and the prevention of flooding in newly constructed urban areas.A distributed hydrological model of SWMM was coupled with a two-dimensional hydrodynamic model(SWE-ELW)of HEC-RAS to simulate and analyze flood control and drainage in the southern water network of Fuyang City in Anhui P…查看全部>>
