Study on the Runoff Simulation of Urban Rainstorm Based on SCS Model
Rainstorms have been frequently occurred and caused serious urban waterlogging disaster in China recent years.A runoff simulation method has been explored based on the rainfall intensity formula, as well as the combination of Chicago Rainfall Process Line Formula and SCS model in this paper.Because of its heavy rainstorm, Tangxunhulake basin in Wuhan was selected as the study area and to simulate the runoff process in different return periods.The results show that the cumulative runoff ranges from 22.3 to 45.3 million m3, and the net increased storage volume ranges from 10.02to 32.87 million m3;the return flow period of more than 20 years would affect the surrounding urban areas and cause damage to some extent.The proposed method of this study is simple and reliable, and can provide a great reference for the waterlogging calculation in urban areas.
