Analysis of Pollutants of Sewage of Oceanic Outfall on the Water Quality

The article analyses and predicts the hydrodynamic feature of study area on the basis of Mike21FM model. And then it predicts the contributed concentration field of the pollutants. The paper assesses the influence of the petroleum in discharge of sewage on the marine water quality nearby.
