摘要
介绍了SWMM模型原理,包括地表产流子系统演算、地表汇流子系统演算和传输子系统流量演算。经长沙市霞凝港区的实测资料检验,证明该模型在港区小流域的雨洪分析中有较高的精度,洪峰流量最大相对误差仅为7.85%,可用于港区雨水排水的径流模拟。
This paper presents the principles of SWMM model, which consists mainly of three parts, i.e. ground surface rainfall sub-system calculation, overland flow sub-system calculation and storm-sewer flow subsystem calculation. It is verified by the observed data of Xianing Port Area in Changsha City that the model is of high accuracy, with the greatest relative error of the peak flow of only 7.85%, thus can be used in runoff simulation of harbor rainfall drainage system.
