EFFICIENCY IN USING MODERN TECHNOLOGIES FOR MEASURING FLOWS IN THE MIRISHKOR TRUNK CHANNEL SYSTEM
Abstract
The article discusses the issues of measurements of water consumption in water management systems, which is regarded as one of the most pressing problems nowadays. The UR-6 A irrigation canal, which brings water from the Mirishkor main canal, was selected as the subject of the study. The field studies carried out at the PK-1 + 00 picket of the UR-6 A irrigation canal, together with hydrometers of the Mirishkor irrigation systems control using a GR-21m1 spinner as well as a SonTek S5 doppler, analyzed the degree of accuracy of the two measuring instruments, the ease of their use at the measurement site as well as economic efficiency. According to the measurements, the average water flow, determined by the hydrometric spinner, was Q = 2.39 m3/s, the average water flow, measured using the Doppler tool, was Q = 2.261 m3/s
