Planning for Stormwater Runoff Control: A Case Study in China
In order to control stormwater runoff and reduce water pollution,stormwater management planning was carried out in Futian River watershed of Shenzhen city,China.Major rain harvesting methods for different land use,including roof rainwater collection,road rainwater collection and green space rainwater infiltration were investigated.Respective harvesting methods in mountain areas and urban areas were conducted.The instantaneous unit hydrograph (IUH) method and the EPA Storm Water Management Model (SWMM) were recommended for flow routing in mountain areas and urban areas.The runoff coefficient of Futian River watershed reduces from 0.6 to 0.52 after stormwater management.The result shows Futian River watershed has great potential in rain harvesting.The planning practice has a significant effect on runoff reduction.This case of stormwater utilization planning provides useful information to stormwater managers and site designers,and can serve as example for other cities with similar situation.
