Redondo Beach King Harbor, California, Design for Wave Protection. Coastal Model Investigation
A 1:75-scale, three dimensional hydraulic model was used to investigate the design of proposed breakwater modifications at Redondo Beach King Harbor, with respect to wave conditions in the harbor. The model reproduced approx. 8,800 ft of the shoreline and included the existing harbor and offshore bathymetry in the Pacific Ocean to a depth of -60 ft. Improvement plans consisted of raising the crest elevation of portions on the north breakwater both with and without installing a transition layer of small stone, and extending the length and crest elevation of the south breakwater. An 80-ft-long unidirectional, spectral wave generator, and an automated data acquisition and control system were used in model operation. Conclusions from test results include: 1) Existing conditions are characterized by very rough and turbulent wave conditions with wave heights up to 8 ft along the moles for 50-year conditions. 2) Of the 14 improvement plans tests, Plan 14 was considered optimal considering wave protection and construction costs. 3) Comprehensive wave-height tests conducted for Plan 14 indicated that the established wave-height criteria in the harbor would be met or only slightly exceeded for waves up to a 100-year recurrence from 240 and 260 deg.
