| Abstract: |
The model equations with three-dimensional, time-dependent, nonlinear Navier-Stokes equations are transformed by sigma-transformation.On the basis of the process splitting technique, the fluid flow problems are divided into two parts, the vertically-integrated equations (external mode) and the vertical structure equations (internal mode).The first set of equations being the propagation of the tidal waves and the ADI numerical scheme has been chosen to solve them.Concerning the vertical structure equations, they are solved by means of leapfrog stepping procedure.
The main features of the tide and associated tidal current in the Bohai Sea are examined with this 3-D model.To have a good reproduction of vertical structure, the rnlumn is divided into 10 layers and the M2 tidal current is computed in detail.The simulation reveal the spatial structure and some important characteristics of the tidal current of the Bohai Sea.The application of the 3-D model to forecasting of the tidal current in the Bohai Sea has been performed as an illustranon. |
