Abstract
The study is devoted to the spread of passive impurities from a point source located off the west coast of the Kerch Strait. On the basis of three-dimensional dynamic model with constant density, calculations are carried out to establish a model field of currents under the influence of intense constant wind of different directions. The obtained spatial distributions of velocity fields and turbulent diffusion coefficients were used as input information for the integration of the passive impurity transport model. It was found that the main pollution zones in this period of integration of the model are the areas of the Kerch port and the port of Crimea. In the southern and south-western winds possible release of pollutants into the Sea of Azov, which will increase the load on the environmental situation in the sea. In the south-east and north-west wind exposure pollutants are concentrated in the region of the Kerch Strait. Wind of north, east and north-east directions lead to the spread of pollutants in the Black Sea. At the same time, the predominant nature of the north-eastern winds leads to increased ventilation of the Kerch Strait.
