Geoecological screening of the state of small and medium-sized river basins to assess the impact of measures for the operation of hydraulic structures

Abstract

The relevance of the work is due to the annual increase in anthropogenic load on components of geosystems of basins of small and medium rivers. The paper proposes an integrated approach to solving the main problem using a combination of classical and modern methods of analyzing natural systems - the screening method. This paper notes the need for screening control during the implementation of measures for the operation of hydraulic structures to assess the current state of catchment basins of small and medium-sized rivers, which includes the forecast of possible changes in the components of geosystems under the influence of anthropogenic load in order to prevent, minimize or eliminate negative environmental and related socio-economic and other consequences and maintain optimal living conditions for the population. Solving the problem using the screening method will make it possible to better analyze the state of catchment areas, in particular, the basins of small and medium rivers with a high anthropogenic load, which will make it possible to promptly identify environmental risks that have a negative impact on the components of geosystems and take more effective measures to eliminate them. The development of a methodology for screening control will make it possible to comprehensively assess the impact of anthropogenic factors on the geoecological state of the catchment area of the Osetr river, to study the current ecological state of the study area, identify the main factors of impact, as well as assess the degree of pollution, zone the study area according to the degree of anthropogenic load, and develop a geoecological passport for the catchment area of the Osetr river.
