Book excerpt: A 1:75-scale three-dimensional hydraulic model was used to investigate the design of proposed modifications in various areas of Redondo Beach King Harbor. The model reproduced approximately 8,800 ft of the California shoreline and included the existing harbor and offshore bathymetry in the Pacific Ocean to a depth of -60 ft. Improvements consisted of raising portions of the north and south breakwaters, flattening the slope of the existing north breakwater in the vicinity of an adjacent mole, and installing a spur on the inside of the north breakwater. An 80-ft-long unidirectional, spectral wave generator and an automated data acquisition and control system were used in model operation. Conclusions include: For test waves from 260 deg, test results for existing conditions indicated severe overtopping of the breakwater adjacent of Mole A and subsequent flooding of the mole. The proposed improvement plan (Plan 1) with additional stone placed on a 100-ft-long section at the outer end of the Galveston seawall (Plan 1A) will minimize overtopping of the breakwater and flooding of the mole. For test waves from 240 deg, the proposed improvements (Plan 2) required modification to minimize overtopping of the breakwater and subsequent flooding of Mole A. Additional stone placed on a 150-ft-long section of the outer end of the Galveston seawall (Plan 2A) was required. The Plan 2 spur, it appeared, could be reduced in elevation (Plan 2A) and minimize wave energy reaching Mole A due to spilling waves propagating northerly over the breakwater. (edc).
