| Abstract: | The MIKE21 numerical model was applied to simulate the tidal current field in Tianjin coastal waters.On this basis,considering the pollutants input of five typical estuaries in Tianjin coastal waters,the COD transport and diffusion range under the action of spring tide and neap tide was calculated.Then the effects of shoreline changes on COD transport and diffusion were analyzed.The results show that shoreline changes have greater impact on COD transport and diffusion range near Beitang estuary and Tianjin port.After the change of the shoreline,the 0.001 mg/L concentration isoline range at the high and low tide of spring tide and neap tide is smaller than before. |
