“…However, to the south of the European part of Russia, the effects of climate change differ from the observed averages for Russia [ 19 , 20 , 21 ]. In particular, in the Volga River basin, observations show a more significant increase in the average annual air temperature up to 2.2 °C during the past 60 years or a mean of 0.036 °C per year [ 20 , 22 ], a decrease in water discharge by 40–60% [ 3 , 19 , 23 , 24 ], and a fluctuation in the moisture supply from a maximum between 1980 and 1994 to minimum values since 2000 [ 20 ]. These changes lead to annual droughts, a lowering of local and regional groundwater levels, shallowing and even drying up of water bodies, and an increase in the total salinity of waters, which negatively affect all components of terrestrial and aquatic ecosystems [ 4 , 6 , 18 , 25 , 26 ].…”

This study investigated the species composition, distribution, and salinity tolerance of macrozoobenthos in 17 small rivers in the southern arid region of the East European Plain, which are characterized by a small channel gradient, slow-flowing or stagnant water bodies, and a wide range of water salinity, varying between 0.18 and 30 g L−1. In total, 156 taxa were found, among which 66 were Diptera species. The study revealed that the formation of benthic communities in the rivers is influenced by natural factors of the catchment basins, including the flat landscape with sparsely developed relief differentiation, climate aridity, and the widespread occurrence of saline soils and groundwater, largely related to the sedimentation of the ancient Caspian Sea and modern climate changes. These conditions are favorable for the occurrence of lacustrine macrozoobenthic species in freshwater, euryhaline, and halophilic ecological groups. The investigation revealed a decrease in species richness in response to an increase in water salinity. The five identified halophilic species Tanytarsus kharaensis, Glyptotendipes salinus, Cricotopus salinophilus, Chironomus salinarius, and Palpomyia schmidti can be used as indicators of river ecosystem salinization.

“…At present, the problem of water supply in arid regions is quite acute and does not lose its relevance [1,6]. One of the most important issues in the process of water supply of the population is the creation of water reserves near settlements for uninterrupted provision of household and drinking needs of the population in the spring and summer period [4].…”

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.
