Analysis of Water Resources in the Arid Region of Saratov Oblast Based on Satellite Information

Abstract

The problem of water supply in arid regions is still topical and needs to be studied. The aim of the study was to develop a program for the analysis of the dynamics of water resources from the satellite images of the Saratov region. The analysis of the images made it possible to create a program for calculation of the water surface area of the water bodies used for estimation of the water reserves dynamics depending on climatic and anthropogenic factors from 2007 to 2022. The water bodies located in the most arid area of the arid region of Saratov region and used by the population for household and drinking water supply were investigated in the work. The results showed a direct marked relationship between the volumes of spring water supply and precipitation. Also revealed a direct high correlation between the reduction of water reserves in summer and the volume of precipitation from May to August. The program and revealed regularities can be used for estimation of water reserves in artificial lakes and rivers of arid regions.
