INFLUENCE OF SURFACE WAVES ON THE DISTRIBUTION OF CONTAMINANTS IN COASTAL AREAS OF SEA

In the present paper, we derive relations which can be used to predict the size of propagation of a polluting impurity cloud or spot  in the pre-coastal area of the sea for the purposes of construction of sewage water outlets and clean sea water inlets in the recreation zones. In paragraph 2 we consider the problem of a conservative impurity flow from the point source towards the sea shore (the problem of a polluting water outlet) taking into account the river flow and the surge of waves over the shore. The third paragraph  deals with the propagation of a polluting impurity from the shore (a linear source) towards the sea where the clean water intake is located. As different from the first problem considered in the second paragraph, in this problem the diffusion turbulence coefficient is determined taking into account longitudinal coastal waves and drifting flows caused by wind. At the end of the paper, we give some numerical results on the impurity  concentration  distribution calculated by the obtained relations for the clean sea water intake structure which is being designed in one of the resort areas of Georgia’s Black sea coast.

This article is a brief Review of activities of the Georgian partner of the ICME Project – “Integrated Coastal Monitoring of Environmental Problems in the Sea Region and the Ways of their Solution” made in the period 2013-2015. It presents main results of compilation of basic data of seawater pollution, geomorphological and hydro-engineering problems in the Poti-Port  and Anaklia regions of Black Sea coast of Georgia and on the  develop of appropriate mathematical models for solution  these problems
