Abstract
The experience of constructing a geoinformational system (GIS) of the Svetlyi Yar irrigation system (Volgograd oblast) for monitoring the status of irrigated lands is considered. The GIS was based on comprehensive information that included remote sensing materials. Analyzing and processing these materials showed that the economic pattern in the area had changed in recent years, the area of irrigated land had decreased significantly, and the irrigation volume had decreased, bringing about a drop in the groundwater level. The structure of crops had also changed, and irrigated soils had entered the desalinization and calcareous invasion stage after the salinization stage of the 1990s.
