摘要： 随着城市的快速发展,城区不透水面积比日益增大。下垫面条件的变化使得降雨径流过程也发生了明显改变。文中以SWMM模型为基础,选取邯郸市城区育德花园小区为实验小区,根据下垫面情况划分成多个子流域,分别按地表产汇流和管网汇流模拟了暴雨在小区的产汇流过程。人工实测出流过程与模型模拟过程的对比分析结果表明,SWMM模型对城市小区的暴雨径流过程模拟效果较好,可以在其他城区推广应用。

Abstract: The urban impervious area ratio is increasing with the rapid development of the cities.The change of the underlying surface condition makes the rainfall-runoff process change obviously.Based on SWMM model,the Yude Garden District in Handan City is selected as the experimental area.According to the condition of the underlying surface,the area is divided into multiple sub basins,the process of runoff yield and concentration in the area is simulated in accordance with surface runoff yield and concentration and pipe network confluence.Through the comparative analysis of the artificial outflow process and simulation process,the SWMM model has better simulation effect of runoff process in the urban,which can be applied in other urbans.

Key words: SWMM model, rainstorm runoff, surface runoff, pipe network confluence
