Prototype tests of the hydraulic performance of one of the dual intake gates of a 22-ft-diameter, flood-control tunnel at Fort Randall Dam were made in an effort to determine the cause of damage to the gate rollers and tracks which was noted after the tunnels had been operated for a year. The investigations included three separate field measurements at heads of 79, 97, and 110 ft on the gate sill, with various combinations of gate openings. Vibration of the riverward gate was measured in both the horizontal and vertical planes with accelerometers, and pressures on the gate leaf were measured with electric pressure cells. Water-surface elevations in the gate well were observed with an electrode-sounding device. Author
