Recommendations for improving the reliability of hydraulic structures in the on-farm network

Abstract

The article examined and evaluated the technical condition of hydraulic structures in the Water Users Association (WUA) with the goal of rational use of available water resources in Central Asia, including the Republic of Uzbekistan, and minimizing the negative impact on the environment. The study examined 297 hydraulic structures in 10 WUAs in the Ferghana (upper), Namangan (middle) and Samarkand (lower) regions of the Republic of Uzbekistan, of which 193 water-measuring structures and their negative impact on the environment were identified. According to the above analysis, the average service area of a water-measuring device in a WUA is 152 hectares, and in accordance with the rules it is recommended that the service area should be between 50-60 hectares. At the same time, scenarios were developed for decommissioning on-farm canals and their hydraulic structures with a logical connection between the main causes of the structures and their causes. WUAs having problems were analyzed and recommendations for their safe and reliable operation and maintenance were provided.
