In order to implement an effective method of water distribution and management, we must have accurate water measurement capabilities. If we can measure the exact amount of water from the reservoir to the main canals, from the main canals to the inter-farm canals, from the interfarm canals to each ear, we guarantee that we will achieve our goal. When determining the characteristics of the main shape and size indicators of rivers and canals, depth measurements are mainly carried out twice in the direction from the left bank to the right bank and vice versa to determine the cross-section of the flow of rivers and canals. The average depth (hур) on each vertical is taken to be equal to the arithmetic mean of the depths measured twice:Today, the need for rivers, lakes, glaciers and groundwater, which are considered sources of fresh water not only in our country but also on Earth, is increasing day by day, and the expansion of the national economy is an urgent issue. Providing water to agriculture, which is the main pillar of the economy, eliminating water-related problems, and ensuring sustainable economic development are of course the main tasks of quantitative study of river waters and their constant measurementenWater resourceriveragricultureeconomycanalwater consumption
