This paper presents the results of oil spill simulation in the northwest of the Persian Gulf, next to Al-Ahmadi oil wells. A two-dimensional depth averaged flow and oil pollution model is developed for coastal water simulation. To increase accuracy advective terms in transport equation were discretized by applying third-order upwind scheme and modified by using GH limiter. The oil spill is considered in two different layers: surface smudge layer and depth emulsion part. The model takes into account the major physiochemical phenomena of oil spill including wind and current speed, oil evaporation, dissolution and coastline deposition. Average monthly wind speed has been used for long-term prediction in the Persian Gulf. Comparing the model result with the actual measured data in the incident sight revealed good agreement for predicting oil spill behavior and model accuracy.
