AB  - In order to comparatively analyze the influence of different fineness of subsurface on flood simulation, 2020.7 floods were selected, and the two-dimensional storage and retention floodplain model with different finenesses was constructed with Arakusa Erxu and Arakusa Sanxu as the research object, and the hour-by-hour water levels (unit: m) of three typical gauging stations at the mouth of the Xianghe River, Xiaoxiao Station, and Jinji Gate were simulated, and the simulation of the flood in the storage and retention floodplain was carried out. The evolution of flood water in the stagnant flood zone was simulated, and the final flood inundation economic loss was counted, and the results were compared and analyzed. The high-detail two-dimensional floodplain model adopts 12.5 m resolution digital elevation data as the model support terrain data, and at the same time, the terrain is dissected by an unstructured grid with a smaller area, whereas the lower-detail two-dimensional floodplain model adopts 30 m resolution digital elevation data, which is a common application, and the area of the grid cell is also relatively larger. The grid cells are relatively larger in area.
