Numerical simulation study on drift and diffusion of Dalian Oil Spill

Abstract

Marine oil spill has long-term harmful impact on both marine ecosystem and economics. Recently as the increase in China’s rapid economic growth, the demand for energy is increasing, leading to the high risk of marine oil spill pollution. So it is essential that we improve emergency response capacity in marine oil spill pollution and develop oil spill prediction and early warning in China. In this study, based on Lagrange tracking approach, we have developed an oil spill model. Combining with high-resolution meteorological and hydrodynamic model, the oil spill model was applied to predict the drift and diffusion processes of Dalian oil spill. The predicted results are well agreed with the analyzed synthetic aperture radar (SAR) image, and provided effective oil spill behaviour prediction to Shandong Maritime Safety Administration.
