Trajectory of sediment deposition at the bottom of water intake structures of pumping stations

Abstract The study of the causes and patterns sediment deposition at bottom water intake structures pumping stations, negative impact sediments on efficiency their operation is one important measures taken to improve recovery system. issues studying determination rate trajectory solid particles were analyzed, main shortcomings in determining parameters particle identified. An equation proposed that allows taking into account concentration flow, properties (density, geometric parameters) as well design dimensions pump station’s advance chamber. obtained calculated results based verified by deposits chamber operating station, which showed spread data does not exceed 7…12 %. At same time, smallest settle end prechamber suction zone. possibility using determine stations.
