Abstract:

Model investigations of Fort Randall Dam were concerned primarily with the hydraulic performance of the chute-type, gate-controlled spillway and four 22-ft-diameter, gate-controlled flood-control tunnels however, a study also was made of the passage of diversion flows through the flood-control and eight 28-ft-diameter power tunnels. Three undistorted models were used in accomplishing the investigations a a 1100-scale comprehensive model for study of spillway flows, b a 150-scale model of the stilling basin for the flood-control tunnels and of the temporary stilling basin for dissipating the energy of diversion flows through the power tunnels, and c a 125-scale model of the flood-control tunnel.
