This model has been run for oil spill accident between Khark Island and Busher Port in winter (2005). Model predicts concentration distribution of oil particles and current speeds and directions for 1.7, 7 and 14 hours after spill accident in the water column in 5,10 and 15 meters levels. Numerical results show that oil particles spread towards Khark Island and away from Busher Port in winter. Diffusion oil particles in the water column due to more turbulence are larger. Spreading follow the flow fields that are in good agreement with flow field observations and valid theories and experiment of data runs.</span></span></span></span></span></span></span></span>
