Asalouyeh  is one of  the most important oil and gas centers in the southwest of Iran, Bushehr province and on the northern coast of the Persian Gulf. Due to the petrochemical and petroleum industries along the coast,oil derivatives leak into the sea, causing pollution of the water basin in the Asalouyeh area and neighboring areas, which is an environmental threat.The GNOME  model is a lagrangian-Eulerian model that is used to find wastewater and contaminated areas. In this paper, to assess the risk of areas affected by the petrochemical effluent contamination of the Asalouyeh coastal area,the refined  petroleum effluent diversified under 3 scenarios with Non-weathering materials, Fuel oil 4 and Fuel oil 6 and each in two volumes of 10 and 100 , set for 2018. Then,wind and flow were analyzed in the area and applied as input file to the model.Subsequently, GIS-based analyzes were used to map and estimate contaminated areas. GIS output estimates and mapping estimates showed that the highest level of contamination was  related to Non-weathering material with an area of 10.92 , which occurred in spring due to increased wind speed and consequently increased water flow. Also, Fuel oil 6 had the highest dispersion, which occurred in the spring. Final results showed that the extent of the contamination with an area of 1.31  reached to the eastern and southeastern parts of Asalouyeh, the Hala and Hara forest area of  Nayband Bay, a national protected area and national park
