Cleveland Harbor, Ohio, Design for the Safe and Efficient Passage of 1000-Ft-Long Vessels at the West (Main) Entrance: Hydraulic Model Investigation.

Abstract : A 1:100-scale (undistorted) hydraulic model of Cleveland Harbor, Ohio, which included the west (main) entrance to Cleveland Harbor opposite the mouth of the Cuyahoga River; approximately 8,800 ft of the harbor shoreline to the east of this entrance, including the western portion of Burke Lakefront Airport; the entire West Basin; Edgewater Marina; and sufficient offshore area in Lake Erie to permit generation of the required test waves, was used to investigate the effects of proposed improvements with respect to ship maneuverability, wave and current action, and riverflow conditions in the western portion of Cleveland Harbor. Proposed improvement plans at the Cleveland Harbor west entrance entailed (a) removal of portions of the existing breakwater spurs; (b) deepening and widening of the existing channel; (c) installation of additional breakwaters; and (d) modifications that involved raising and sealing and/or removal of portions of the existing arrowhead breakwaters. A 10-ft-long remote-controlled model ore carrier (representing a 1,000-ft-long vessel), a 120-ft-long wave generator, a model circulation system, wind generators, and an Automated Data Acquisition and Control System (ADACS) were utilized in model operation.
