Modelling of transboundary spreading of oil spill in the Caspian sea

R.M.Mammadov

In article is given the Caspian Sea oil pollution characteristics, necessity arguments of oil spill modelling development. The basic processes (advective transport, turbulent diffusion, dispersion, evaporation, emulsification, photolysis, sedimentation, biodegradation and gravitational flowing), defining behaviour of oil in the sea environment are stated. Modelling calculations of current and oil spill to the sea are carried our under various hydrometeorological conditions. It is shown that east winds are the most dangerous with relation to Azerbaijan coast pollution as oil moves quickly enough to coast site and time for emergency measures is critically a little. Even in the extreme cases oil flood in the Azerbaijan sector is not dangerous to sectors of other coastal states as on close enough from a point of accident distance concentration of oil in the sea goes down to a level of maximum permissible concentration.
