This paper uses the ADCIRC model to establish a block-scale storm surge inundation model in the Beilun District, Ningbo City, with a land resolution of 5−10 m in the Beilun District. The simulation results show the overall process of inundation flooding urban street buildings, and detail description of the flow of water in the complex distribution of blocks and buildings, as well as changes in water depth near different buildings, which are more refined than previous inundation simulations, reflecting the advantages of block scale grid. Numerical simulation results show that this model can simulate the storm surge process of No. 1211 Typhoon “Haikui” and No. 5612 Typhoon “Wanda” well. Satellite remote sensing images are used to classify features in the Beilun District, and the influence of changes in the friction of different underlying surfaces on inundation simulation is considered. Comparing the results of the simulation experiment without considering the underlying surface friction, the submerged area is reduced by 21.4%, and the water depth in most areas is reduced to 0.1−0.2 m. The block-scale grid shows the degree of water depth reduction and the change of submerged area in different areas.
