The Shchuchinsko-Borovskaya system, consisting of seven large lakes, was studied. Lakes of tectonic origin are located at different absolute levels within the granite massif. The water in the lakes is fresh, less often brackish, and previously has been widely used for agricultural and drinking purposes. Based on monitoring data and analysis of a long-term series of satellite images over the past 30 years, a significant decrease in the level of the lakes and water resources has been revealed. This has affected the ...

The possibility of the application of satellite bathymetry methods was studied in order to obtain quantitative parameters of the depth of the coastal part of the Astana reservoir (Kazakhstan). The relevance of the research is associated with the application of new technologies for the operational evaluation of changes in the level of the water line and the volume of the reservoir, which supplies Nur-Sultan, the capital of Kazakhstan, with drinking water. The initial data were satellite images with different resolu...
