Taking Huinan Town in Shanghai Pudong New Area as the research area, the rainstorm waterlogging model which coupled MIKE URBAN and MIKE 21 by MIKE FLOOD was established. The model was applied in Chuansha area of Pudong New Area to improve the ability to respond to waterlogging disasters. The “June 17th, 2015” rainfall and disaster was selected to verify the model, and satisfied results were obtained. The model was applied in assessing the current rainwater pipe network drainage capacity of the study area, and it shows that most rainwater pipeline doesn't meet the design requirements of one year once rainfall. The region's main waterlogging points and waterlogging reasons were analyzed. The waterlogging situations were simulated under different rainfall recurrent period and different stage boundary conditions, the risks of waterlogging were evaluated as well, so as to provide countermeasures against floods and waterlogging for the Pudong flood control departments.
