Abstract : In October 1984, severe vibrations of the outlet works gate tower of Gillham Dam, southwestern Arkansas, were observed by US Army Corps of Engineers project personnel. The reservoir elevation was about 50 ft above conservation pool when this occurred. Prototype tests were conducted to determine the severity and cause of vibrations of the intake tower at Gillham Dam. The test program measured the vibrations at the intake tower, wet well, and both service gates; sluice pressures upstream and downstream of each service gate; and the air demand through both air vents. The vibration data recorded on the intake tower and the wet well showed a predominant frequency of 4 cps. This correlates with the upstream pressure fluctuations measured. The tests in which motion was most severe occurred when gate 1 was at an opening of 4.8 ft or higher....
