低影响开发措施的城市雨洪控制效果模拟
Simulation of control efficiency of low impact development measures for urban stormwater
摘要
Abstract
A storm water management model (SWMM) was set up in this study to simulate runoff generation and drainage with different types of precipitation in a residential area in Guangzhou City, based on real-time observed rainfall-runoff data and the current drainage network.Combined with the low impact development (LID)module, the influences of permeable pavement, sunken lawns, rain gardens, and combined LID appliances on urban storm water were simulated and analyzed.The results show that both peak flow and the runoff coefficient decreased significantly through application of permeable pavement, sunken lawns, rain gardens, and LID appliances, which was conducive to the drainage of municipal pipe network.The effect of storm water control and utilization was more significant during low-return periods.The decreases of peak flow and the runoff coefficient were more significant when rain gardens were used.The combined LID appliances had more significant effects in reducing peak flow and postponing the time of peak flow.The effect of storm water control and utilization was not significant when permeable pavement and sunken lawns were used.关键词
