暴雨径流管理模型与GIS完全集成技术

摘要

针对暴雨径流管理模型( SWMM)输入文件的制作效率低及误差较大的问题，提出了将SWMM模型整合到基于ArcEngine( AE)二次开发的管网系统中的方法，系统通过借助地理信息系统( GIS)强大的空间分析能力自动划分汇水区，生成研究区域的子汇水区信息，同时结合数据库中的管网属性数据自动生成SWMM的输入文件，避开了人工制作输入文件的复杂过程。实验结果表明，输入文件的制作效率和误差有很大的改善。系统在城市防洪排涝方面，能有效帮助管理者实现动态模拟、直观展示以及防洪预警。%For the low production efficiency and large error for the input file of StormWater Management Model ( SWMM) , the method for integrating SWMM into pipe network system was introduced. The software automatically generated a SWMM Model's input file through the data source, and avoided the complex process of artificial production. The experimental results show that the production efficiency and the error of the input file has been greatly improved. In terms of urban flood control and drainage, the system can effectively help managers achieve dynamic simulation, visual display and flood warning.
