Abstract：Based on the unstructured triangular irregular grid finite volume three-dimensional offshore ocean model(FVCOM),a large-scale three-dimensional hydrodynamic numerical model was construc-ted with mountains as the center radiating outward,including the Yangtze River Estuary,Hangzhou Bay and nearby waters.The accuracy of the model was verified by measured tidal level and tidal current data.The results showed that the numerical simulation results were in good agreement with the meas-ured data,and the model results were meaningful.In addition,on the basis of verifying the reliability of the model,the hydrodynamic numerical simulation was carried out in the Dayangshan sea water area,and the complex flow regime and flow energy distribution of the waterway in the sea area were ana-lyzed.The results can be used for further research on the influence of hydrodynamic forces on sediment movement,and have certain scientific significance for preventing ships from running aground in the waterway.
