Abstract : The drop structure proposed for Cayuga Inlet was studied on a 1:20-scale model to determine the adequacy of the structure. Particular emphasis was placed on selection of a basin which would operate satisfactorily with tailwater depths greater than that required for a satisfactory hydraulic jump. The original design structure proved unsatisfactory, as it did not provide adequate water levels upstream from the structure; addition of a 3-ft-high crest sill was required. Use of a 12-ft-radius abutment wall instead of the wing walls of the original design reduced drawdown at the abutments, improved basin action, and reduced construction costs. Baffle piers were not required in the stilling basin, and it was found that the length of the apron could be reduced from 60 to 50 ft without a noticeable effect on energy dissipation. (Author)
