Book Description
Tests were conducted in bay 8 of the low-overflow spillway at Ozark Dam, Arkansas River, Arkansas, in September 1974 to study vibrations and pressure fluctuations as related to flow through the spillway. Pressures were measured on the spillway sill to determine whether fluctuations are correlated with structural vibrations. Velocity distributions were measured to study boundary layer development and to determine an equivalent roughness for the spillway surface. Gate vibrations were measured to attempt to confirm model results. Pressure fluctuations on the low overflow spillway did not exhibit a root-mean-square (RMS) value large enough to be considered as a source of excitation of spillway vibration. The structure appeared to be vibrating at a natural frequency of 2.7 cps. Structural vibration amplitude was relatively small. Gate vibrations appeared to be independent of opening. The equivalent sand grain roughness Ks determined for the Ozark spillway (0.0061 ft) supplements previous data. Theoretical boundary layer thicknesses agree with the measured velocity profiles.
