- Abstract:
- Surface configuration of green land was tested by using a large-scale outdoor low impact development (LID) infiltration bed and an artificial rainfall device. Infiltration and runoff volumes of different green land surface configuration indices under different rainfall scenarios were measured. The optimal surface configuration of green land was obtained by the experiment which met the rainfall conditions and soil types in Guangdong. According to the test results, the corresponding LID simulation module was constructed in storm water management model (SWMM) to provide reasonable parameter settings for optimization and evaluation of green land configuration. The case study showed that the improvement of green land surface configuration could reduce the overflow of urban drainage system. The project combined the research results of outdoor experiment and simulation modeling, and it could provide a scientific basis for large-scale planning, layout and evaluation of LID measures in sponge city construction in Guangdong.
