Improvement of water accounting for irrigation systems
Annotatsiya
Abstract The use of water metering devices operating on hydraulic energy for open canals of on-farm irrigation systems, the error in measuring water flow is substantiated. In addition, the article provides an analysis of the water metering in main canals, the possibility of using hydraulic structures. In modern conditions of agricultural development, a special role is assigned to hydro-reclamation, as one of the main factors that guarantee high stable yields of agricultural crops. At present, when water has become an expensive commodity, for the rational and efficient operation of irrigation systems, operational and objective water metering must be carried out, and hydraulic structures on the canals must ensure the supply of specified costs. To control the consumption of water in open canals of irrigation systems, mobile and stationary gauging stations are used -water metering points.
