摘　　要：针对武澄锡虞区遭遇五年一遇暴雨情况,采用适合于平原河网及城市区域产汇流模拟的水文水力模型--MIKE 11模型,将其中的NAM模型和HD模块进行耦合,根据望虞河西控工程调度方案,由设计暴雨推求评价区河道涝水特征值。通过排涝水文计算,模拟对比望虞河西岸封闭前后,评价区遭遇五年一遇暴雨时,河网节点的水位、流量过程,分析望虞河西岸封闭对评价区水系、洪水位、高水位持续时间及半高地淹没状况的影响。模型计算结果表明,望虞河西控工程实施后,望虞河西岸地区最高水位普遍抬升,受影响区域内高水位持续时间增长,对部分半高地存在潜在淹没影响。For the condition of facing the rainstorm that appears every five years in Wuchengxiyu region ,the hydrologic and hydraulic model suitable for plain river network areas and urban areas-MIKE 11 model are used as examples .According to the west bank con-trol project in Wangyu River ,coupling the NAM model and the HD model ,the river flooding water is calculated through design rain-storm .Through hydraulic calculation ,the flooding water of Wangyu River is contrasted before and after the west bank control pro-ject and the river system ,water level and duration of high water level are evaluated .Model calculation results show that ,after the west bank control project ,the highest water level of west bank is generally uplifted and the period of high water level in the affected areas lasts longer than before .
