摘　　要：为了评估西控工程对望虞河西岸地区造成的防洪影响,以望虞河西岸为研究区域并结合其水文特性,构建了适合于模拟平原河网地区产汇流过程的MIKE11水文水力模型并利用当地降雨、水位等实测资料进行了率定。通过模拟50年一遇设计暴雨情况下的不同工况,得到研究区域内水系各节点的水位等要素变化情况,并依此分析了西控工程对望虞河西岸地区造成的防洪影响。结果表明:西控工程运行后,研究区域内重要节点的最高水位抬升明显,部分地区有遭受洪水淹没的风险;MIKE11水文水力模型对于分析平原河网地区河流沿线闸控影响具有较高的应用价值。In order to evaluate the impact of west bank control engineering on flood control in the area of WangYu River, the paper took the west basin of Wangyu River as the study area and based on hydrologi- cal characteristics to constructe the MIKE11 hydrological and hydraulic model which was suitable to simu- late runoff process of a river network plain area, and to use the local rainfall and water level measured da- ta to calibrate. Through simulating the fifferent conditions of designed storm one every 50 years, the paper got the change situation of water level each node in the river network. According to the calculation, and analyzed the impact of west bank control engineering on flood control in the west area of Wangyu River. The results showed that the highest water level of important node in the study uplift distinctly, some places are in risk of flood submerging. MIKEll hydrological and hydraulic model has a high application value on analyzing the influence of water gate control in the river network plain area.
