Book Description
Model investigation verified that vertical vibration of the Bonneville spillway gates was caused by flow instability beneath the gate. When the gate bottom was submerged by tailwater and the gate was at certain openings, the line of flow control shifted back and forth between the gate seal near the center of the bottom and the upstream face of the gate. Pressure changes accompanying the control shifts created large changes in vertical force on the upstream half of the gate bottom. A bottom shape with a longer lip for better flow control was developed. The new shape was structurally feasible, usable in either set of existing gate slots without modification of embedded seal plates, and operable at all gate openings with negligible vertical vibration. Other shapes not usable with existing seal plates were developed but were considered less suitable.
