雨水管理模型（SWMM）是基于中国核心区域北京亦庄经济开发区的数据建立的，包括地形变化、下垫面条件和雨水管网系统等信息。选取了北京两次典型暴雨事件的数据；模型参数进行了标定；并验证了仿真结果的准确性。计算了不同重现期设计降水情景下的模拟区域平均深度。通过这些结果的比较，提出了在开发区缺乏实测雨流数据的情况下处理校准和验证的有效措施。绿地和广场用地的雨洪消化能力明显优于其他用地。这对于SWMM在我国大规模城市地区的应用和推广具有重要的指导意义。
Storm Water Management Model (SWMM) is established based on the data of the Yizhuang Beijing Economic Development Zone in the core region of China, including the information of the terrain variation, the underlying surface conditions and the storm sewer system. The data of two typical rainstorm events in Beijing were selected; the model parameters were calibrated; and the simulation accuracy results were validated. The simulation regional average depth in different return periods designed precipitation scenarios were calculated. From a comparison of these results, potent measures to deal with the calibration and validation in a condition of the development zone lack of measured rainfall flow data have been suggested. The green space and square land is much better than the others in rain flood digestion. It is important and instructive for the application and popularization of SWMM in large scale-urban areas in China.
