Detached Breakwater and Improved Navigation Entrance Lorain Harbor, Lorain, Ohio. Hydraulic Model Investigation

摘要

A 1:125-scale model of the harbor and adjacent areas, equipped with wave-generating and -measuring devices, was used to determine the optimum length and alignment of a proposed detached breakwater lakeward of the existing breakwater system, and the optimum shape and width of navigation opening protect the harbor entrance and mooring area from storm waves and currents, and to improve navigation conditions for large vessels. Five of the ten plans tested met the wave-height and current-velocity criteria. The recommended plan of these five, based on economy of construction, provides for a 2250-ft-long detacted breakwater and the removal of 300 ft of the existing east breakwater. (Author)
