The Impact of Physical Processes on Oil Pollution Diffusion in the Persian Gulf

Abstract

In this paper, the distribution of pollution in various conditions is simulated by a hydrodynamic model to determine the behavior of the oil pollution spill into the sea and the effect of the physical processes such as wind, heat fluxes and wind stress on the distribution of these contaminants. Four scenarios are designed to examine the impact of these physical processes in the transport and diffusion of the oil pollution released within the surface layer. COHERENS model was used to simulate the oil pollution transport and diffusion, which coupled with contaminant and biological modules, has the ability to solve transport equation using sigma coordinate in the vertical direction and Cartesian coordinate in horizontal. The results of this numerical simulation can be used in providing appropriate solutions to prevent oil from spreading further in the region.
