Study of hydraulic parameters for concreting channels

Abstract

Abstract Irrigation channels plays particular importance role to provide water for irrigated areas. In recent years, the irrigation channels of Central Asia have been negatively affected by deformation phenomena. As a result, their hydraulic parameters changed and their throughput decreased. The results of recent studies in the field of the phenomena of deformations in open and in the planning of irrigation channels show that a lot of work has been completed. Ensuring the static and dynamic stability of the channels, increasing the efficiency of the channels currently require to cover the channels with concrete cladding. A high cost of covering the channels with concrete cladding brings reveals the problems in these works. The best solution is to reduce concrete consumption. The article proposes a method for projecting a concrete channel from the condition of a hydraulically most advantageous section. According to the proposed method, the consumption of concrete mixture is reduced by 36% and increased the dynamic stability of the channel (when assessing the nanotransport ability of the channel) is increased by 26%. The rehabilitee of research results are confirmed by the formulas used in practice.
