Numerical modelling of the sea level under the actions of the tide and strong wind in the Bohai Sea

In this paper, the numerical modelling of the tidal level and current in the Bohai Sea was carried out with ADI method, by taking the sum of four main tidal components M₂, S₂K₂, O₁ as the open boundary condition.The calculated values were consistent with the predicted ones (the observed values in the case of calm) in the Tidal Table.On the basis of the modelling of the tide, the sea level and current fields under the effects of strong wind were simulated.The calculated results were also quite satisfactory.
