Abstract
With urbanization, the proportion of land surface hardening increases, urban stormwater issues have become increasingly prominent. Based on "sponge city" by China, Quzhou old town used infiltration trenchs, permeable pavements, and rain gardens taking the total amount of runoff and peak control as goal in this paper.The paper established city rainwater model of the study area with SWMM and simulated every LID facility using LID module in the model.The research shows that infiltration trenchs had not only best effects on controlling node flooding ,but also strongest control on reducing peak flow and delaying time of appearance of flood peak.The control of total runoff valume with permeable pavements was the most effective way.
