摘要

This study discusses the low impact development (LID) facility planning of Phase 1 project of the Guangzhou Educational Town in China. The project site will deploy LID facilities to reduce the flood risk and non-point pollution, and to utilize the rainwater for landscaping and irrigation. In addition to traditional LID facilities, two newly developed LID features such as gravel infiltration retention system and depressive green field are firstly used in the project. The low and high density LID configurations were deployed. SWMM model was used to stimulate runoffs with and without LID facility deployment. The simulation results show that deploying low and high density LID configurations can improve the drainage system from handling 5-year design storm event to 10 and 20-year storm events, respectively. The high density LID configuration was recommended as implementing scheme.
