Based on the delft3d technique of the famous software in the world, we establish the twodimensional tidal mathematical model. Firstly we verify the model with the real-measured tidal level and current. Then we analyze the distribution of tidal current in the simulated area after the calculated result of the model is consistent with the real-measured data. At last, we study the situation of Tianjin port industrial zone after completion of near-term projects, and give the detailed characteristics of the tide and current near the engineering site, and evaluate the navigation safety of the logistics wharf engineering in Tianjin Fangtong Group port industrial zone.
