Abstract
The study of sedimentation processes in the clarifiers in the drip irrigation system was carried out in the fields of farms in the Bukhara, Kogon, Peshku, and Romiton districts of the Bukhara region, which are supplied with water from the Amudarya river. During the research, methods of field observation, generally accepted methods in hydraulics, and methods of comparing experimental results with hydraulic calculations were used. Hydraulic calculation of turbid sedimentation process in sediments was performed by A.G.Khachatryan method. As a result, a graph of the relationship between the settling length and the settling rate of the mud in was developed for different water consumption. As the length of the settling tank increases, the settling rate of the mud increases, i.e., the settling rate of the 41 m long settling tank is 30-40%, while that of the 800 m length is 70-80%. If 20 ha of land is irrigated in 6 plots, then 3.33 ha of land is irrigated in each plot. The water norm required for 1 irrigation of cotton on 3.33 ha of land is 900-950 m3, while the average is 250-300 m3 / ha. If 2 chambers with a length of 10 x 40 m (depth 2-2.5 m) are taken in each chamber, then in the first chamber, 35-40% of the distilled water passes into the second chamber, and in 8 hours, it becomes another 35-45 %, and clear water can be sent to the irrigation system through pumping units. In such cases, water should be constantly supplied to the first chamber from the ditch until the end of 1 irrigation of 20 ha.
