Description: Technical Memorandum
Synopsis: This technical memorandum describes the model studies made at the U.S. Waterways Experiment Station in connection with the design of the spillway and stilling basin for the Possum Kingdom Dam. The tests indicate that: (A.) The mininrum length of apron required tor a hydraulic-jump basin is 200 ft. (B.) To produce a complete hydraulic jump, the apron would need to be raised approximately 10 ft. (C.) A submerged jump would be created on an apron which had a varied elevation conforming to the contour of the shale formation. (D.) The excess energy in the overfall from the spillway may be effectively dissipated by an apron which is considerably shorter than required for a complete hydraulic jump if a sill is placed on the downstream end of the apron. The basin design considered satisfactory was of this type, being 100 ft. long and provided with a notched sill on the lower end. NOTE: This file is large.
