Hindcast Simulation of Oil Spill Incident off the Taean Coast in South Korea Using Oil Spreading and Diffusion Particle Model

Abstract

In this study, we developed an oil spreading and diffusion particle model. The model can calculate oil spreading by particle model to use Fay's equations(1969) and the effectiveness was evidenced. We conducted hindcast simulation of oil spill incident of Hebei Spilit, South Korea in 2007 using the model. We compared calculation and observation of spilled oil, its applicability was verified. We discussed about vertical and horizontal eddy viscosity coefficients because their coefficients affected the simulation results. We proposed vertical eddy viscosity coefficient equal to 0.10m2/s and horizontal eddy viscosity coefficient equal to 30m2/s.
