Abstract : A 1:75-scale undistorted hydraulic model of the lower 5400 ft of Cattaraugus Creek and sufficient offshore area in Lake Erie to permit generation of the required test waves was used to investigate the arrangement and design of certain proposed improvements with respect to shoaling, wave protection, and flood control. The proposed improvement plans consisted of (1) breakwaters in Lake Erie at the mouth of Cattaugus Creek, aggregating about 2300 ft in length; (2) a berm, about 700 ft in length, extending northward from the inner end of the north breakwater to high ground; (3) a 120-ft-wide, 8-ft-deep entrance channel, about 1900 ft in length, extending from the 8-ft contour in the lake to the maneuvering area; (4) a 6-ft-deep maneuvering area 300 ft wide by 600 ft long; (5) a 120-ft-wide, 6-ft-deep channel, extending upstream approximately 1900 ft from the maneuvering area; (6) a riprapped friction section extending about 750 ft upstream from the navigation channel through the New York Central Railroad bridge; (7) two levees on the left bank aggregating about 770 ft in length; and (8) development of recreational facilities. A 60-ft-long wave generator, granulated nylon and crushed coal tracer materials, a model circulation system, an ice simulation material, and an automated data acquisition and control system (ADACS) were utilized in model operation.
