Abstract: Located in the Zhongxin River Basin, the study focused on the Lianping County section, where a coupled 1D-2D hydrodynamic model was constructed using the IFMS. The observed flood data of Zhongxin station from July 4 to July 6,2022 was used for parameter calibration, and the flood inundation extent for various return periods was simulated. The results indicate that the study area shows a good flood resilience with a recurrence interval of up to 20 years. However, for floods with a return period of 20 years or greater, the residential areas are likely to experience varying degrees of flooding. This suggests that enhanced flood control measures are necessary to strengthen the region's resilience to flooding.
