Abstract
In the Republic of Kazakhstan, the general state of water metering processes in melioration systems, including open irrigation networks, is assessed as extremely unsatisfactory. It does not meet modern metrological requirements for state water resources accounting. The main problems include low accuracy of water level and flow measurements, slow data collection, significant water losses due to infrastructure deterioration (up to 70% in some areas), filtration (about 40%) and evaporation. This leads to irrational use of resources and reduced efficiency of agricultural irrigation.
Water metering processes in open irrigation networks of the Zhambyl region are of fundamental importance for improving the efficiency of water resources use in arid climate conditions. The article considers the state of water metering processes in open irrigation networks of the Zhambyl region. The main methods and means of measuring water flow, including channel and hydraulic methods, as well as modern approaches to automation of water metering are described. Particular attention is paid to the technical condition of hydrometric posts, problems of their equipment and operation. It is noted that a significant part of water metering points are in an unsatisfactory condition due to long-term operation and the lack of certification documentation. Initiatives for digitalization and automation of water metering processes are analyzed, including Kazvodkhoz plans to reconstruct canals and introduce automated systems on inter-farm canals. It is noted that, given limited funding, a radical modernization of metering points seems difficult. In this regard, an appropriate direction is the introduction of more accessible and economically sound measurement tools and methods adapted to the specifics of open irrigation canals.
