Abstract
Short-duration heavy rainfall and storms can easily cause waterlogging disasters in low-lying urban areas,posing serious threats to road operations and daily life.To effectively prevent and manage urban flooding,it is essential to conduct simulation analyses of urban hydrological processes using reliable technologies,identify key flooding risk factors,and optimize drainage systems.In this study,the MIKE 21 and MIKE Urban models were applied to quickly assess surface water flow and ponding in the evaluation area.The MIKE FLOOD coupled model was used to simulate urban waterlogging under extreme rainfall scenarios,identify bottlenecks in the drainage network within major ponding areas,and propose optimization strategies.The findings provide valuable references for urban flood risk management and water-related disaster mitigation.关键词
