摘要

雨洪管理模型(SWMM)是广泛应用的城市雨水模拟和分析软件,子汇水区是SWMM模型中基本计算单元,通过分析总结SWMM模型的降雨径流水文概念模型、子汇水区产流模型和汇流模型,结合模型原理,提出参数赋值建议,并针对子汇水区宽度初步赋值方法存在的问题,提出以地表漫流长度作为计算子汇水区宽度的基础方法,根据子汇水区最大集水距离加权计算地表漫流长度,并对加权计算的结果对比。

Abstract:

Storm Water Management Model (SWMM) is a widely used urban rainwater simulation and analysis software, the sub-catchment is the basic calculation unit in the SWMM model. Through the analysis of the rainfall runoff hydrological conceptual model, runoff yield and concentration mathematical model for SWMM sub-catchment, some suggestions on parameter assignment are put forward the application. In order to solve the problem of sub-catchment width value assignment,this paper proposes to take the length of the overland flow path as the basic method to calculate the width of the sub-catchment area, and to calculate the length by weighting the length of sub-catchment concentration.

Key words:storm water management model(SWMM)sub-catchmentrunoff yield and concentration modeloverland flow path
