航道船舶事故溢油风险影响预测及管理

number of channel are used to transport construction materials and coal, Although the possibility of serious oil spills is extremely small, oil spills by ship collision accidents are taken place frequently. In this article, combine with environmental impact assessment for channel renovation, environmental risk prediction and risk management for oil spill by ship collision accidents on channel have been done. By analyzing the physical and chemistry change of oil after the oil enter waters, the diffusion and movement of oil is simulated to predict the place where the oil would be appear and the range where the oil can affect; In addition, preventive measures and emergency preparedness for oil spills by ship collision accidents are discussed in this article. All these provide a scientific basis for the deal with oil spills and decision making.
