Research on Urban Storm Flood Processes under Two Measures: Detention Pond and Retention Pond

Article Preview

Abstract:

The detention pond and the retention pond are effective means for flood control. In this paper, two different storm runoff processes, used the detention pond and the retention pond, were simulated by SWMM. Through analyzing the results, the detention pond and the retention pond can control the flood obviously. Furthermore, the action effects of detention pond and the retention pond were discussed. In the end, the paper put forwards that the suitable flood control measures should be chosen by regional hydrology characteristics, maximum permitted discharge of downstream, engineering economics and so on.
