Abstract : Tests were conducted on a 1:60-scale model of the Kaysinger Bluff Dam spillway to determine the discharge characteristics of the spillway, stilling basin performance, flow conditions in the outlet channel, and the adequacy of various sizes of riprap in the outlet channel. The spillway consisted of an ogee crest with four 40-ft-wide by 47.3-ft-high tainter gates and a hydraulic-jump type stilling basin. The discharge capacity of the original design spillway was slightly less than expected; however, the capacity was increased by increasing the radius of the abutments. An unstable surging of flow that occurred on the upstream side of the spillway gates with the original design during operation with large partial gate openings was eliminated by decreasing the length of the gate piers upstream from the gates. Although the original design stilling basin performed satisfactorily, a more economical and efficient design was developed. The discharges at which failure of the riprap placed on the side slopes of the outlet channel will occur were determined. (Author)
