Abstract
The creation of scientific and technical foundations for the reconstruction of irrigation and drainage systems on old irrigated lands located on the right bank above the floodplain terrace of the Syrdarya River is an urgent task for scientists of the republic. The existing irrigation and drainage systems in the study area do not meet modern requirements for irrigation and collector-drainage networks, which, in combination with agrotechnical measures, should create an optimal reclamation regime in soils. The main criterion of which is the maximum productivity of a unit of water and land resources with minimal costs for the reconstruction and operation of irrigation and drainage systems, agricultural costs for growing crops and the cost of creating a favorable environmental situation in the region. The study area is characterized by low-mineralized groundwater, non-saline soil and imperfect irrigation and collector-drainage network. The existing collector-drainage network is open. The presence of subpressure water in the study area requires the conversion of an open collector-drainage network to vertical drainage
