Waterlogging Risk Assessment of Urban Parking Lots based on LisFlood-SWMM Coupling Model
As a result of global warming and climate change,heavy rainstorms are becoming more frequent.With the improvement of urbanization level,the built-up area is increasing which leads to high flood disaster risk,and water soaking occurs frequently in urban waterlogging.This paper takes urban parking lots in Futian District of Shenzhen City as the research object,uses POI(Point of Interest)data crawling method to construct a parking lot database in Futian District,and simulates the flooding situation under different rainfall scenarios based on LisFlood-SWMM model.Based on this,the risk level of waterlogging caused by waterlogging is divided,and the waterlogging risk assessment of urban parking lots under different rainfall scenarios is obtained,and risk prevention measures are proposed,which has reference for the risk assessment of waterlogging in urban parking lots in China.
