“…According to our measurements, the flow of traction sediments in the section of the Amudarya River in the head part of the Karshi Main Channel was 10...28%, in the area of the head part the Amu-Bukhara Main Channel 5...37%. In the calculations, approximate values of the water consumptions of traction sediments in the intra-annual context can be taken: during the flood period -15 ... 20 and during the low water period -20 ... 27% of the flow of suspended sediments [12][13][14][15][16][17][18][19][20].…”

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 real object of research was the real input channels of the ABMCh with a length of 31 and 35 km from AB-1 to AB-2, which are the main channels providing water to the Bukhara and Navoi regions, which, in turn, are the main strategic raw material bases of cotton in the southern region of the Republic of Uzbekistan [16][17][18][19][20].…”

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.

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.
