Abstract : Hydraulic model investigations for Barkley Dam were concerned with the orientation of the lock, spillway, and powerhouse structures; determination of the feasibility of discharging the lock culverts into the spillway stilling basin; development of optimum designs for the laterally sloping stilling basin, training walls, and lock culvert discharge manifolds; and verification of hydraulic loads on the lock emergency gate. Three undistorted models were used in accomplishing the investigations: (a) a 1:120-scale comprehensive model which reproduced about 3 miles of the river and included the lock, the spillway, the powerhouse, and portions of the earth embankments on each side of these concrete structures; (b) a 1:36-scale section model which reproduced five spillway gate bays and the downstream lock guide wall, and included the lock culvert discharge manifolds; and (c) a 1:25-scale model of the lock emergency gate. Model tests verified the adequacy of the proposed position and alignment for the lock structure. Navigation conditions were improved by the removal of a portion of an existing railroad embankment located upstream from the spillway, and by a slight realignment of the right bank of the exit channel.
