Aiming at the problem of campus waterlogging in Hefei City, this paper constructs a 1D-2D coupled model based on Mike Flood. Firstly, GIS was used to obtain the distribution information of the five types of land surface in the study area by analyzing satellite images, and to automatically divide the catchment areas. Secondly, combined with the measured elevations by using the RTK device, the 3 m×3 m high-precision DEM data of the study area were obtained. A 1D pipeline model and a 2D surface model in the study area were constructed using Mike Urban and Mike 21 respectively, and the two models were coupled on Mike Flood. At the same time, a flowmeter, a liquid level meter and a rain gauge were installed in the campus. The model was calibrated by two measured rainfall events according to R2 and ENSE. Finally, the Chicago rainfall pattern was used to design rainfall scenarios for the 5, 10, 30 and 50 years of recurrence periods, and the severity, inundation range and inundation depth of nodes and pipelines in different rainfall processes were simulated. The simulation results show that main causes for the waterlogging in the campus are due to unreasonable sub-catchment designs, which resulted in limited absorption of rain peak runoff and serious overload of the pipe network.
