ABSTRACT:
An apparatus is disclosed for admitting atmospheric air to a bounded volume of air on a downstream side of a crest gate where the bounded volume is defined by the gate and a curtain of water spilling over the gate. The apparatus comprises a plurality of rigid conduits secured to the gate and sized sufficient to have a first opening in communication with atmospheric air and second opening in communication with the bounded volume of air. The rigid conduits are secured to the gate and spaced along the length of the gate to divide the curtain of water flowing over the gate into a plurality of separate water currents. Permitting communication between atmospheric air and the bounded volume of air, the rigid conduits act to abate damaging vibration to the gate caused by the flow of water over the crest of the gate.
