Abstract
LIDs are frequently utilized measures in urban waterlogging management in the world and the evaluation of their effectiveness through model gets a lot of attention in urban hydrological research. In this study, a typical urban unit of Handan, China was selected, and regional SWMM model was calibrated and validated through measured maximum waterlogging depths (MWD) of typical positions; the LIDs effectiveness on runoff process in different return period events were evaluated through the SWMM. The results show that LIDs have an effect on decreasing total runoff quantity and peak discharge and the effectiveness is more significant when the return period is small. The research provides a technical support to the scientific management of local flood and waterlogging and supplies a reference to local Sponge City planning.
