Abstract
The article raises the question of the influence on surface water bodies downstream of the Dnipro River, taking into account the geological influence on one river on another. Such studies are necessary to establish the factors influencing the composition of surface waters of rivers and to determine the stability of the ecological quality of surface water bodies such as the left tributaries of the Dnipro – Desna, Sula, Psel, Vorskla and Samara. Detection of the influence on upstream tributaries on downstream, taking into account the presence of groundwater, was carried out using the example of chloride dynamics. Correlational dependences were constructed between chloride concentrations in observation posts located the closest to Dnipro. The obtained results confirm the influence of tributaries on each other. In order to confirm the conclusions obtained regarding the influence on rivers due to groundwater, studies with other impurities present in tributaries are needed. The obtained results can be used for the development and implementation of a mathematical model for forecasting the ecological state of surface water bodies within the sub-basin.
