Improving methods of increasing reliability without dam water intake

The paper presents the results of field and experimental research in the damless water intake of the KMCh in the Amu Darya River. Under the conditions of the Amu Darya, with a large volume of irrigated water and intensive wandering of the river flow on a wide floodplain, the provision of a guaranteed damless water intake requires the implementation of channel control works to detach the pioneer ditch and systematically clean it from entering during the period of operation. The article improves the method of increasing the reliability of the damless water intake and the calculations of the route and the boundaries of the pioneer ditch, depending on the river flow. It also provides hydraulic schemes for improving the condition of a damless water intake and recommendations for the rational use and placement of a fleet of dredgers when laying a ditch route and cleaning it.
