Purpose. The purpose of this work is, based on numerical model experiments, to examine the propagation patterns of anthropogenic suspended matter by wind currents from the area adjacent to the oil pier into the open coastal waters and adjacent bays; to estimate the linear scale of the pier's impact on the surrounding water environment; to compare the modeling results with expedition data; and to identify the parts of the water area that experience the maximum anthropogenic load.

Methods and Results. The Felzenbaum three-dimensional barotropic linear model, generalized to account for Rayleigh friction, was used to calculate currents. The process of suspended matter propagation due to currents and turbulent diffusion is described by the equation in divergent form. The suspended matter source is located at the northern tip of the pier. Numerical experiments were performed for winds from the 8 main directions. The processes of propagation and accumulation of pollutants in the studied water area were also examined by analyzing the actual concentration fields of total suspended matter and dissolved oil products based on data from three expeditions.

Conclusions. According to the performed model calculations and analysis of observational data, the impact radius of the pier on the surrounding water environment (in the suspended matter concentration field) is estimated at 0.5–1.0 miles, and the maximum anthropogenic load falls on the northern parts of Kazachya and Kamyshovaya bays.
