【Abstract】 A hydrodynamical model for oilspill simulation in archipelagic waters with multiple open boundary conditions is set up and simulation/forecast tests in Zhoushan dingpu Port are performed.A horizontal high resolution orthogonal curvilinear grid system and a turbulence closure submodel to the 2.5 power are incorporated in the model.The three dimensional (3D) primitive equation sets together with their boundary conditions are solved by finite difference technique according to implicit/semi implicit scheme.Preliminary study shows that the model can reproduce the most of important hydrodynamic features in the waters of interest,simulate/forecast 3D tidal current,wind driven current and their interaction,and thus provide a real time flow field for oilspill simulation.更多还原
