ON THE INFLUENCE OF SOLAR ACTIVITY ON THE HYDROCHEMICAL COMPOSITION OF THE WATER OF THE SAMARA RIVER
A brief description of the water in the Samara River is given. The data on hydrochemical parameters of the river water for the period 2005-2015 are given. Indicators are marked out, sharply changing their values in the period under review. For such studies the indicator-the oxygen concentration-was selected. It was revealed with the help of statistical methods that the series of observations under consideration is divided into two samples with diff erent sample averages. It is graphically proved that the sharp jump in oxygen concentration was due to the infl uence of solar activity. The dependence of the sulfate content in the Samara River on solar activity for the period from 2005 to 2015 was studied. Calculations have been made that prove the hypothesis of the infl uence of solar activity on the hydrochemical composition of the water of the Samara River.
