Abstract：In order to study the influences on the transport and dispersion of the offshore discharged pollutants,MIKE21 is used to establish the tide current numerical model of Bohai and northern of Huanghai.Nested meshes are used near the outlet region to get accurate results of the surrounding water.Tidal current field was simulated by the hydrodynamic model and the model was reasonable by comparing the results with field measurement.On this basis,the transport and dispersion of the offshore discharged pollutants,COD,were simulated under different environment situation and studied the wind field and the source's influence on transport and dispersion of pollutants.The results show that the wind field changed the velocity and direction of pollutants transport;comparing with point source,the linear source promotes the rate of transport and dispersion near by the outlet of discharge pipe.
