Fundamentals of hydraulic calculations of water softening structures in drip irrigation technology (in case of Zarafshan river)

This article presents the results of field studies on the study of the process of sediment settling in the settling tanks of the drip irrigation system carried out on farms in the Akdarya and Ishtikhan districts of the Samarkand region, which are supplied with water from the Zarafshan River. Calculation of the process of settling sediments in sedimentation tanks was carried out according to the method of A.G.Khachatryan, and a graph of the relationship between the length of the sedimentation tank and the degree of sediment clarification was determined. As a result, recommendations have been developed to substantiate the optimal parameters of sedimentation tanks for various natural conditions.
