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.
