The world production of crude oil is about 3 billion tons per year. The overall objective of the model in present study is supporting the decision makers in planning and conducting preventive and emergency interventions. The conservative equation for the slick dynamics was derived from layer-averaged Navier-Stokes (LNS) equations, averaged over the slick thickness. Eulerian approach is applied across the model, based on nonlinear shallow water Reynolds-averaged Navier-Stokes (RANS) equations. Wetting and drying fronts of intertidal zone and moving boundary are treated within the numerical model. A highly accurate algorithm has been used through an alternating-direction implicit (ADI) scheme which separates the operators into locally one-dimensional (LOD) components. For validation of oil spill model, predicted results are compared with analytical solution. Besides that, the model is set up for Persian Gulf region under real weather conditions.
