Abstract: Urban floods have become a trouble for sustainable urban development. Taking Beiyangyuan Campus of Tianjin University as the study area, a coupled SWMM and MIKE21 model was constructed to explore the urban hydrological effects and the flood risk under low impact development (LID). The results show that permeable pavement has the best runoff control effect, and even implementing a small percentage of LID practices can effectively control runoff. Duration time is an important influence on flood risk, and the impact of flow velocity on flood risk is very small in plain cities.
