Abstract
Long-term climatic changes have led to a decrease in the water content of a number of Russian rivers. In the pool of R. The Don phase of low water content has been going on since 2007. In addition, due to climate warming, significant fluctuations in the intra-annual hydrological regime are observed. The climatic situation and high anthropogenic pressure on water resources complicate the conditions for the development of irrigated agriculture. At the same time, there is an obvious need to increase the area of irrigated land on the Lower Don. The authors of the article propose a number of measures that contribute to the effective development of the Nizhny Don water management complex against the background of water scarcity. The possibility of replenishing the flow of the Don River is considered. In the conditions of the Azov-Don basin, a geoinformation web-based decision support system for integrated management of the reclamation and water management complex developed at the Federal Scientific Center for Hydraulic Engineering and Melioration named after A.N. Kostyakov can be used. The proposed hydrodynamic model of the Lower Don can be used in order to form optimal modes of operation of the Tsimlyansk hydroelectric complex in the interests of agricultural and fisheries water users.
