Abstract

For areas that are urbanized rapidly, the practice of Low Impact Development (LID) has gained an important place in stormwater management and urban planning due to its capability and beneficial effects in restoring the original hydrological cycle. The performances of LID alternatives can vary substantially due to different climate conditions. In this study, the SWMM 5 model was applied to simulate the performances on water balance and flood control of these LID alternatives by using 17 years GSMaP rainfall data (from 2000 to 2016) for Tianjin City. A new evaluation method was proposed in this study including the efficiency index for water balance (Iw).It showed that rain harvest system presents comparative advantage in controlling water balance for high imperious urbanized area, then it is porous pavement, and the last is bio retention. This information about the performances of each LID alternative can help decision makers develop a better storm management strategy
