Flood-Control Outlet Works for Blakely Mountain Dam, Ouachita River, Arkansas: Hydraulic Model Investigation
The hydraulic characteristics of all elements of the design for the Blakely Mountain Dam flood-control outlet works were studied in a 1:25-scale model. Special attention was given to flow conditions in the conduit for various pool elevations and openings of the control gates. Unusual flow conditions were encountered in this investigation as a result of an 80-ft drop in the section between the intake structure and conduit proper. Under certain flow conditions, hydraulic jumps formed in rapid succession near the foot of the drop and passed through the conduit to the stilling basin. Attempts made to revise the transition for improvement of these conditions were unsuccessful. However, the intake structure control gates can be operated in such a way as to preclude these unstable flow conditions.
