A three-dimensional hydrodynamic model of oil spill simulation in a multi-open-boundary archipelago was established and simulated and forecasted experimentally in Dingpu Harbor of Zhoushan.The model was constructed using a high-resolution horizontal curve orthogonal grid and a 2.5-order turbulence closed model , The three-dimensional initial dynamic equations with initial and boundary conditions are solved implicitly or semi-implicitly by finite difference.The preliminary experiments show that the model attaches importance to many important hydrodynamic characteristics in the harbor, and can simulate or predict the three-dimensional tidal current in the sea area, Wind flow and its interaction, and provide real-time flow field for oil spill simulation
