HYDROECOLOGICAL ASSESSMENT OF SURFACE WATERS OF THE OSETR RIVER BASIN

В.А. Широкова

Abstract

Anthropogenic pressure on water resources in Moscow and Moscow region has reached a critical level, due to the decrease in surface runoff and the transition of rivers to groundwater supply during low water. With the formation of runoff, the hydrological and hydrochemical parameters of water change dramatically ? wastewater discharges from settlements and industrial plants cause great damage to the ecology of the river, and the possibility of dilution and the ability to self-purification of water decrease. Any river, especially a small one, as close as possible to consumers, reflects the ecological state of the environment. The quality of water in rivers depends on the state of their basins. This leads to the need for integrated environmental monitoring, which will help to track not only the change in water quality in small rivers, but also to determine their impact on larger water bodies and to create a picture of the anthropogenic impact as a whole. The article summarizes the results of a comprehensive environmental assessment of the Osetr river basin in 2018 based on the results of engineering and environmental surveys obtained in the framework of environmental monitoring from June 20 to July 29, 2018 on the rivers Oka and Osetr in the Zaraysky, Lukhovitsky and Kolomensky districts. The influence of anthropogenic factors on the ecological state of the Sturgeon river basin is considered. The current ecological state of the river is assessed, the forecast of possible changes in the environment under the influence of anthropogenic load is presented in order to prevent, minimize or eliminate harmful and undesirable environmental and related social, economic and other consequences and preserve optimal living conditions of the population.
