This paper deals with numerical modelling of organic pollutant (COD) in the Bohai Sea. One of the main purposes is intended to provide a useful numerical model for predicting the water quality in the Bohai Sea.A two-dimensional advective-dispersion equation and a set of corresponding ADI difference scheme are used. The computations were executed on the computer in a specially designed program IMEP-TD for modelling dispersion of pollutant. From the modelling results, present water quality in the Bohai Sea is, generally speaking, still fine except the areas near the estuaries and inlets where sea water is contaminated. To protect ecosystem in the Bohai Sea, the inflow load should not keep increasing rapidly. 相似文献
