MODERNIZATION OF WATER FLOW MEASUREMENT IN OPEN IRRIGATION SYSTEMS USING THE SLOPE-AREA METHOD
Аннотация
This article describes two methods for determining water flow in open irrigation systems: “speed - area” and “slope - area”. The authors considered the problem of its modernization using the existing method for determining water flow “slope - area” in open irrigation systems. The essence of the issue is the remote transfer of parameters necessary for calculating water flow in open irrigation systems and improving the means of their processing. In scientific studies conducted by the authors, the required hydraulic parameters were studied using the “slope - area” and “speed - area” water flow methods. Based on experimentally obtained data, the relative error in determining water flow was calculated. The maximum error in measuring water flow using the “slope-area” method compared to the “speed - area” method was 0.7%. The result of scientific research has shown that the “slope-area” method is important for improving the means of water flow.
