Abstract

Abstract. Zomin water reservoir is a seasonally controlled reservoir built on a river bed. It was built on the Zominsoy river, located 8 kilometers from the center of the district, in the Zomin district of the Jizzakh region. The reservoir is designed to irrigate 7,820 hectares of land in Zomin district. In order to study the current technical condition of hydrotechnical facilities in the Zomin water reservoir, natural observation-measurement works were carried out. After checking the technical condition of hydrotechnical structures in the reservoir, it was found that there are the following defects: on the upper slope of the dam, from the scythe to the berm, at the mark 916.0 m., no deformation and damage was detected, at the mark 916.0 m, the subsidence of the berm from PK4-00 to PK5÷16 is visible, the covering plates are cracked, at the bottom there are gaps. When built according to the project, they will be 600m. At the 902 m mark, the entire berm was repaired and part of the lower slope was repaired with an area of 1566 m². In the area of marks 902-909 m, between the marks PK 5÷16-PK 6-00, the slope is broken, the total area reaches 200 m², on the berm at the mark 888.5 m. there are old concrete fragments of the upper berm and the slope of the dam. The water reservoir and other related and adjacent hydrotechnical facilities were monitored. Based on the results of natural observation-measurement works conducted in order to study the current technical condition of the hydrotechnical structures in the Zomin water reservoir, the technical condition of the hydrotechnical structures in the reservoir was assessed as being in a dangerous state.
