Abstract (en)

[origin: WO9940261A1] The invention concerns a structure for crossing a head drop on a waterway, comprising a succession of at least three substantially horizontal head races (41, 42, 43), separated by gates (31) mobile between an open position and a closed position. The invention also concerns a method for crossing a head drop, which consists in successively controlling the structure gates (31) so as to enable the water in two adjacent head races to be at the same level. Finally the invention concerns a navigation canal with vertical walls comprising a structure for head race crossing.
