Changes in the Volga River Flow in the Lower Reaches Under the Natural and Anthropogenic Factors Influence (20 th—21st Centuries)
https://doi.org/10.31857/S2587556620020156
Abstract
One of the features of our time is the general deterioration of the aquatic ecological situation, the cause of which is often anthropogenic activity amplified by changes in natural factors. Using the temporary analogy method, hydrological and hydrochemical indicators of the water regime of the Volga lower reaches are compared for periods that differ in the degree and nature of anthropogenic impact. The Volga lower reaches refer to the territory, including watercourses of the Volga-Akhtuba floodplain, delta and Western steppe ilmens belonging to the Lower Volga and considered by the authors within the Astrakhan oblast. Data on the total annual runoff and its annual redistribution make it possible to identify the ratio of anthropogenic and natural factors’ contribution to its formation. The regulatory effect of reservoirs in which river water from the entire catchment of the river accumulates, their mixing and the chemical composition final formation, lead to irreversible consequences and natural processes manifestations.

- Changes in hydrological and chemical indicators are important for adjusting rules for the regulation of the river flow by a cascade of reservoirs.
- Changes in runoff led to the depletion of water in the lower reaches of the river by suspended solids due to their accumulation in the reservoir.
- Incorrect regulation leads to a general delay in the peak of flood for 45–50 days; the minimum mineralization is 0.26 g/l in July–August.
- Maximum discharge at dangerous marks of 620–670 cm can lead to irreversible processes.
