Abstract

The article highlights the main characteristics and constructive elements of on-farm channels used in the republic. The cross—sectional shapes of the channels are described - trapezoidal, rectangular and parabolic, their parameters, including width, building height and water flow regime. The hydraulic flow parameters and flow modes are mentioned as proof that most channels operate in a calm mode (the number of Froudot is less than 1).

The problems of accounting for water resources arising from siltation and overgrowth of canals with vegetation are also considered in detail, which makes it difficult to operate water meters and keep accurate records. To solve these problems, it is proposed to use portable weirs and develop specialized water measuring devices capable of accounting for both flooded and free flow modes.

The article emphasizes the importance of accurate water metering in conditions of paid water use, where the measurement accuracy should be no more than +/- 5%. Examples of successful operation of water measuring facilities are presented and measures are described to optimize the operation of these facilities to improve measurement accuracy and simplify operational conditions.

Water is supplied to on-farm (intra-farm) canals through main (magistral) and inter-farm canals. At the head of these on-farm canals, various types of water measurement devices — such as stationary channels, thin-walled weirs, flumes, and other structures — are installed to ensure accurate water accounting.
