Abstract : Tests were conducted on the downstream leaf of the two-leaf, vertical-lift emergency gate to determine whether the gate would perform satisfactorily under flowing-water conditions approximating an emergency. The test operation used to simulate an emergency consisted of lowering the downstream leaf to the full-down position and then raising it to the initial damming position with the lock-emptying valves fully open and the downstream miter gate closed. Measurements included gate position, gate hoist loads, gate vibration, and water-surface elevations during the test operation; flow conditions in the lock were also observed. (Author)
