Serial Information: Journal of the Hydraulics Division, 1961, Vol. 87, Issue 5, Pg. 63-86

Document Type: Journal Paper


Violent vibrations may occur at dam or weir gates being subjected simultaneously to overflow and underflow; model studies have been made to evaluate frequency and magnitude of exciting forces for different types of gates and aprons; design criteria and basic mechanism of excitation are presented.
