Increasing of the accuracy of measuring of volumetric flow and volume on hydroeconomic and irrigation systems is urgent today. It can be implemented by further development of the theoretical basis for determining the flow using flumes, given the actual conditions of operation. Analyzed the generalized algorithm for calculating discharge characteristics of flumes with different spatial configurations, based on the theory of critical depth. Clarifying of discharge and velocity coefficients, which functionally depend on the gauge in the approach part of flume and determined by successive iterative operations, was made. The results of clarifying stage-discharge relationship of Venturi-flume is given. The comparison and analysis of the discharge characteristics standardized Venturi-flume, obtained using a generalized flow depending on the head, and iterative method for clarified discharge and velocity coefficients, is conducted.References
