Oil spill simulation in the Khark Island region

In this paper, the movement of an oil spill around the Khark Island has been studied, using the hydrographic information of the Persian Gulf region and the Mike21 software. To obtain the water flow flux, a model with an irregular triangular network containing 11325 nodes was assumed and the tidal level of Hengam Island in the Strait of Hormuz and the land boundary condition on the coast were considered. Then the tidal currents in the Khark region were simulated by considering 3 open boundaries and one land boundary (the Bushehr coast). In order to calibrate the information, the tidal level in Khark station was compared with the output of the model tidal level. Based on the results of the model, the amount of water level fluctuations caused by the tides from February 15-25, 2011 were calculated to be in the range of 0.33 to 2.27 meters and the speed of the tidal currents were calculated from 0 to 0.7 meters per second. Also, the amount of water level fluctuations caused by the tides from 10 to 20 August 2011 were 0.36 to 2.19 meters and the speed of tidal currents were 0 to 0.6 meters per second. Based on the value of current obtained from the model for a station, the tidal current time series was plotted and its time-space equation was obtained. To obtain the path taken by the oil spill, the time for the spill to reach full emulsion and thus stop, is obtained using Adios2 software. In 2011 the tidal currents obtained in February were faster than August and as a result, in February 2011, there were a lot of fluctuations in the movement of the oil spill.
