In this article, using the example of the Silinka River in the city of Komsomolsk-on-Amur, the influence of various factors on the formation and transportation of sediments in the river, such as sediments, dissolved substances, such as the gross form of zinc, is estimated. The paper uses a multiple regression model to identify the influence of some external factors on the level of contamination of bottom sediments with zinc and presents the results of numerical modeling that allow us to assess changes in the "water – bottom sediments" system under the influence of various factors. The work is important for understanding ecological processes in rivers and can be used to develop methods for managing and protecting water resources.
