摘要
针对SWMM操作界面建模过程繁琐、准确性差和基于SWMM二次开发建模法技术要求较高、难以推广的问题,提出基于地理信息系统(GIS)预处理的SWMM模型快速构建方法。该法首先利用GIS实现雨水管网空间结构的合理性检查、子排水区的自动划分和特征信息的准确提取,再将信息直接输入模型,.inp文件构建SWMM模型。案例模拟结果表明,该方法合理可靠,简便易行。
Modeling and operational interface of Storm Water Management Model(SWMM) is complicated and not accurate, which further limits the secondary development and wide application of this technology. The present study proposed a rapid construction of SWMM model. Rationality check of spatial structure of storm sewers, automatic creation of subcatchments and accurate extraction of characteristic information were conducted. Then the SWMM model was constructed by importing the featured information into the.inp files. Results revealed that easily available and accurate data could be obtained from the constructed SWMM model.
