Assessment of flood control effect under low impact developmentin East Ho Chong Watershed, Guangzhou City
摘要
Abstract
With the rapid progress of urbanization in China and the deepening of the concept of Sponge City, Low Impact Development (LID) measures have attracted more and more attention all over the country.In order to evaluate the effect of flood control on LID measures, the urban flood model of East Ho Chong watershed is constructed based on SWMM model.Then the suitable LID measures are selected for the study area, and the flood control effect of the LID measures is analyzed by using the design rainfall with the return period of 0.5, 1, 2, 5, and 10 years.The results showed that LID measures can effectively reduce the peak flow, runoff and delay the peak time.They also had good effect on reducing pollutant loads of first flush runoff, and the runoff and pollutant reduction rate decreased with the increase of the return period.关键词
