numerical simulation of oil spill movement on makran coast using combination of finite volume modeling and gnome

The finite volume method is one of the mathematical ways that was applied for tracking oil spills along the makran coast. the gnome model was used for comparison and validation of the calculation results. after deriving the governing equations and boundary conditions, the area is meshed for suitable accuracy, and flow data was obtained from noaa’s real-time ocean forecast system (rtofs) for 90 days (2160 hours). four locations were selected: one(first) point near the strait of hormuz, two points (second and third) near bays on the makran coast, and another (forth) near the pakistan border. at each point, 1000 liters of medium crude oil were released. results showed that the currents in the hormuz strait had a significant impact on the first point, and the pollution spread over two-thirds of makran’s coast within three months. the second and third points affected the coastlines inside the bays, while the fourth point showed pollution spreading toward pakistan's coast. the results were compared with gnome, and the average differences for all the locations were 92.33%, 92.28%, 91.03%, and 92.40%, respectively.
