“…At the same time, the development of measures to improve the operational regime by reducing the introduction of turbid sediments into pumping stations is among the important tasks, creation of a mathematical model that reflects the movement of the flow in the supply channel, regulation of the normal water level in the fore-chamber. In this direction, it is important to develop new approaches to assessing channel processes to ensure the culvert capacity of the channel of the inlet channel of pumping stations [1][2][3][4][5][6][7].…”

In studies conducted in 2017-2020. It has been proved that the erosion and erosion of the Amu Darya's banks, which occur due to rapid and uneven changes in its channel, requires large expenditures for bringing water to the Amu-Bukhara channel with a damless water intake. An analysis of the pumping station data shows that the uninterrupted movement of water in the system water intake-distribution-channel-sediment retention system-system-fore-chamber-suction pipes-pumping unit-pressure pipes-consumer largely depends on the reliable operation of the structures that make up the system. As a result of the rise of water with a high content of turbidity, hydroabrasive erosion of pumping units occurs, and their service life is reduced. The article discusses the installation of sedimentation tanks in the water supply channel to the pumping station to reduce the amount of turbidity in the water; it is determined that to take the effective value of the number, the sweep angle α has the boundary condition αps.inlet≤44° in the area behind the traverse dam. The angle at the exit from the clarifier is determined αsump=180° and corners αps.inlet≤44° on the compression zone of dams on the concreted part at the entrance to the antechamber of the pumping station Clarifiers built on these parameters provide a reduction in water turbidity.

“…A change in the schedule of the water supply to the pumping station and a change in the hydraulic and alluvial flow regimes in the channel of supply channels significantly change the natural course of the channel process, and a forecast of this change is required. Therefore, the problem of studying channel processes and calculating morphometric characteristics in the channel of the inlet channels of pumping stations, which affect their throughput, has always attracted the attention of many scientists [1][2][3][4][5][6][7]. However, despite the abundant work devoted to this problem, its solution is still far from practical completion.…”

The article discusses methods for ensuring guaranteed water intake and the process of sedimentation in the head sedimentation tank. Based on the results of a full-scale study of the supply channel, a recommendation was developed to improve its operation. The results of surveys of the hydraulic and alluvial regimes of sediments in the channel of supply channels are analyzed and summarized as well as the organization of cleaning work and recommendations for the appropriate placement of dredgers along the channel length. The arrangement of dredgers is carried out depending on the distribution of sediment volumes along the length of the channel, taking into account the type and performance of each dredger.

The article presents the results of a study of the mode of inflow and dynamics of sedimentation on the inlet part of the canal. The results of field studies of the state of the channel situation in the supply channels of pumping stations are studied. The process of siltation of the head sump of pumping stations is analyzed. A method for regulating solid runoff into the inlet sections of the canal has been developed. And also by the nature of the change in the hydraulic elements of the flow, the time of siltation of the sump and cleaning the length of the investigated section of the channel were determined. Based on the results of a full-scale study of the supply channel, a recommendation was developed to improve its operation.
