Abstract: 

In many countries of the world, there is a deterioration in the geoecological state of water bodies, associated with a significantly increased anthropogenic impact on natural waters. At the same time, the guaranteed quality of water resources and its reliability are ensured by comparing the realized quality and the guaranteed one. This article discusses models for the entry and movement of pollutants contained in the aquatic environment. Based on the currently used approaches and water pollution criteria, a set of parallel programs for high-performance computing systems has been developed, which allows modeling of the processes under consideration, as well as assessing risks and vulnerabilities in relation to anthropogenic impacts, zoning the water area of a shallow water body in accordance with the levels of anthropogenic loads, environmental design from the standpoint of sustainable development.
