Factors for the efficient use of water distribution facilities

Abstract

In this article, the situation in the selected area was completely investigated to avoid problems that arise when the water distribution facility is in a faulty position. The condition of the hydrotechnical constructions was evaluated. The priority of work on repair and construction of hydraulic structures was defined. As a result of the proper operation of hydrotechnical constructions, a uniform distribution of the volume of water necessary for irrigation of crops throughout the canal, in its upper, middle, and lower parts, was achieved. To implement these activities, first of all hydraulic engineers were trained in the management, repair, and construction of new hydraulic structures. The project documentation (business plan) for the repair hydraulic structures and construction of a new one was developed. On this basis, the repair and construction of new hydraulic structures were carried out. There were given recommendations to the specialists on improving the durability of hydrotechnical constructions. According to the recommendations it is planned to check the state of hydrotechnical constructions after each water and to register them. Several concepts have been proposed to extend the life of the hydrotechnical construction. By repairing and building new hydrotechnical constructions, in the middle and bottom of the canal, and all water distribution canals the water supply to 1015 beneficiaries has been improved. It was achieved an increase in crop yield by 15% and 22% of water savings.

State of the inter-farm irrigation canal: in the case of Khorezm province, Uzbekistan

“…In order to save water resources in irrigated agriculture, it is necessary to ensure the efficient operation of irrigation networks in the efficient use of available water resources, the introduction of water-efficient irrigation technologies [1,[5][6][7].…”

“…At the same time, it is planned to increase the share of concrete-lined canals in the modernization of irrigation systems, modernization of control and measuring equipment and notification systems in hydraulic structures, the introduction of digital technologies in hydrological posts [2,3,10].…”

“…Many scientists have focused on the rational use of water resources and ensuring the proper functioning of irrigation networks in times of water shortage, the use of collectorditch mineralization in irrigation through biological treatment and the use of irrigation water-saving methods in the field. including: Avlakulov M., Balla D., Omar M., Maassen S., Hamidov A., Khamidov M., Isabaev K., Matyakubov B., Begmatov I. and others [4][5][6][7][8][9][10][11][12][13][14][15][16].…”

“…A number of scientists have studied the waste of water in irrigation networks in the country, as well as monitoring and repair of hydraulic structures in the canal, construction of new and application of water-saving irrigation technologies in the field, optimization of hydraulic parameters of canals, assessment and improvement of reclamation of irrigated lands, these are Bazarov D., Yangiev A., Isabaev K., Matyakubov B. and others [8][9][10][11][12][13][14][15][16].…”

Consideration of climatic factors in the operating mode of hydraulic facilities in the Amudarya river basin

“…The rapid development of agriculture and an increase in the need for irrigation of lands, characteristic of the hot climate of Central Asia, and an increase in water consumption by the population of the republic led to a sharp change in the regime of movement and nonstationary movement of the flow of water flow in rivers [14][15][16][17][18][19][20]. To provide agriculture with the required volume of water, the design and construction of many hydraulic structures and the reconstruction of existing facilities are required.…”
