Abstract: Yuqing River Basin is a typical waterlogging prone area on the west side of Nansi Lake. The SWMM software is used to simulate the urban waterlogging process, and the model of sub catchment and drainage ditch (pipe)is used to build the waterlogging model of Yuqing River plain depression basin based on SWMM. The rationality of the calculation results of runoff yield and the results of waterlogging and inundation are analyzed. The results show that the model is reasonable and reliable, which can provide support for the control of plain depression. The research can provide reference for waterlogging research in the similar areas.
