Book Description
When it was designed and constructed, the spillway for Bonneville Dam was unprecedented insofar as the magnitude of flow was concerned; the adopted plan was based on results of more than 170 experiments in a hydraulic model. As an additional measure of safety, an 80-ft-wide apron of reinforced concrete was placed downstream from the stilling basin in order to protect the structure from the effects of undercutting in the erosible foundation material. Eight baffles were reconstructed to a shape recommended after tests made in 1941-1942 in a 1:48-scale model at the Carnegie Institute of Technology, Pittsburgh, Pennsylvania. The Carnegie studies also indicated that even the original baffle piers would be relatively cavitation free if small gate openings were used and if the spillway flow were distributed among as many gates as possible.
