A Change in the Salt Regime of Irrigated Lands under Irrigation Development and its Impact on the Salinity of Rivers-Water Receivers

The paper considers the problem of irrigation development in the zone of insufficient moisture, changes in the water-salt regime of irrigated lands and the impact of irrigation on the change in the level of groundwater, its mineralization. For the territory of the irrigation system, the problems of determining the total evaporation (by the method of A. I. Budagovsky) and irrigation regime are considered. As a consequence of irrigation, the problem of influence of salts from the territory of the irrigation system on the mineralization of rivers-water receivers. To assess the latter, the basin method was applied.
