In order to explore the evolution law of urban waterlogging process under different rainstorm scenarios, taking Dahongmen Drainage Area in Beijing as an example, an SWMM and InfoWorks ICM-2D coupled urban rainstorm waterlogging model was constructed to simulate and analyze the drainage capacity of pipe network, surface inundation and waterlogging risk under different return periods of rainfall in the study area. The results show that the coupled model of SWMM and InfoWorks ICM-2D has good applicability in the simulation of rainstorm waterlogging in the study area. The drainage capacity of more than 70% of pipelines in the study area is less than the design standard of 5-year return period. As the rainfall return period increases, the number of overflow nodes and overloaded pipelines increases, and the overload duration increases. However, the increase range of overload duration of overflow nodes decreases. Waterlogging prone areas and medium to high risk areas are mainly distribute in the central part and the concave bridge area in southeast part of the study area. As the return period of rainfall increases, the depth and range of waterlogging in waterlogged areas increase, and the proportion of areas with a depth of more than 0.2m increases. Low risk areas mainly transform into high risk areas, with fewer transforming into extremely high risk areas.
