К вопросу повышения водообеспеченности Верхне-кубанской оросительной системы Краснодарского края

Abstract

The efficiency of the use of irrigated lands and the receipt of project yields of agricultural crops is associated with the technical condition of the GTS of the reclamation complex, which ensures the management of flood runoff and water intake for irrigation, which, according to various expert estimates, is characterized as satisfactory and unsatisfactory for most structures. The purpose of the study was to develop measures to improve the water supply of the Upper Kuban irrigation system of the Krasnodar Territory by reconstructing the hydroelectric complex on the Novokuban Canal. The analysis of long-term data on the runoff of the river. Kuban and carried out survey and topographic surveys of the Novokuban canal hydroelectric complex. According to the results of the study, it was noted that in 2022, with an annual plan for the supply of water to consumers of 12.12 million cub. meters, the actual water withdrawal amounted to 5.87 million cub. meters, of which 5.28 million cub. meters were used for irrigation, and out of 8.32 thousand hectares of irrigated land, only 3.31 thousand hectares were irrigated. It has been established that the gates of the water control facility are out of order, due to which the canal incurs unproductive expenses during floods, and an emergency discharge creates backwater in the canal bed, which creates emergency situations. An action plan has been developed for the reconstruction of the hydroelectric complex, including the construction of a reinforced concrete water intake with the installation of sluice-regulators with flat gates on the main channel of the canal and the discharge channel with the replacement of culverts. These repair and restoration works will improve the safety of the operation of the Novokuban Canal and the water supply of the Upper Kuban irrigation system, the involvement of existing and the introduction of new irrigated lands, and the expansion of the sowing structure of highly profitable agricultural crops that are responsive to irrigation.
