Key factors of the expected deterioration of the ecological condition of the Lower Dnieper in the modern period due to the technogenic violation of the regulated river waters flow regime

Abstract

In this scientific paper, an assessment of the potential negative ecological consequences for the territory of the Lower Dnieper and the Dnieper-Buh mouth region, which should be expected in the coming years under the influence of man-made disruption of the regime of regulated river water inflow and a significant decrease in the water level in the water system of the studied region, was carried out. The impact of a decrease in the water level, an increase in its salinity, the arrival of a significant amount of pollutants from the Kakhovka Reservoir and a number of other abiotic factors on the future development of the water ecosystem of the region was analyzed. On the basis of the analyzed materials, the main ways of avoiding the deepening of negative ecological consequences caused by the violation of the water regime on the Lower Dnieper were determined.
