| Abstract: | In order to increase the resolution in the numerical simulation of tidal currents, this paper studies emphatically the numerical treatment of special topography such as piers, narrow islands, port mouth, and opening of piers with dimensions shorter than the step size of numerical grids. It takes the Xida Dam of Lianyungang as an example of simulation, and obtains satisfactory results. |
