Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Army Corps of Engineers has investigated various measures for storm damage reduction at Redondo Beach/King Harbor, CA. Numerical models have been used to investigate the effects of local bathymetry on the transformation of deepwater swell. Documents produced by the U.S. Army Engineer District, Los Angeles, point out discrepancies between these model computations and observations during actual storms in 1983 and 1988. The Los Angeles District also questioned the accuracy of theoretical models in general, for areas of complex bathymetry such as Redondo Beach, and argued that the results from the RCPWAVE model "misrepresent actual conditions." There has been a growing consensus to call for the testing of model capabilities. This report responds to that call, and compares results from the refraction model RCPWAVE to measured waves near the Redondo breakwaters. The study also compares results from the spectral refection model STWAVE against tile same measurements. Results of these comparisons are as follows: (a) Computations from both RCPWAVE and STWAVE are in poor agreement (low correlation coefficients) with the field measurements for H> 1.5 m. (b) RCPWAVE tends to overestimate wave heights in general. (c) STWAVE wave heights appear to be more accurate than RCPWAVE, but their underestimations may be unacceptable in some cases. (d) Both the field measurements and the model computations indicate no significant tidal influence on wave transformation. (e) Field measurements fail to support the wave-height relationship H = kH(o) inherent in the model computations. (f) Correlation changes significantly with increasing measured wave height. Therefore, extrapolation of the present results beyond those measured (3.3 m for maximum Ho) requires caution.

Available in PDF, EPUB and Kindle. Book excerpt: Three separate and distinct (although interrelated) problems exist at Redondo Beach King Harbor, California, at the present time: recurring, but infrequent, structural damage to the breakwater; excessive wave activity in the harbor caused by waves penetrating through and overtopping the permeable rubble-mound breakwater; and shoaling of the harbor navigation channel and boat mooring area. The US Army Engineer Waterways Experiment Station was requested to: (a) perform a water wave refraction/diffraction/shoaling analysis of the 1983 winter storms to determine the wave characteristics and frequencies-of-occurrence at the breakwater structure site for the extreme storm events of historical record and for the higher sea waves which overtop the lower portion of the breakwater on an average annual basis; (b) determine the magnitude of wave penetration through the permeable rubble-mound structure, overtopping of the structure, and total wave transmission into the harbor; (c) evaluate the effect of raising the crest elevation of the structure on wave transmission into the harbor; (d) estimate the structure armor stone required for stability based on the return period of storm waves of various heights; and (e) propose alternative structural measures for reducing excess waves in Basin 3 and reducing harbor shoaling by sediment penetration through the breakwater. Keywords: Armor stone, Chemical grouts, Overtopping, Permeability, Refraction, Rubble-mound breakwater, Storm damage, Transmission, Water waves.

Available in PDF, EPUB and Kindle. Book excerpt: Field wave data were acquired at Redondo Beach Breakwater, CA, by the Prototype Measurement and Analysis Branch of the U.S. Army Engineer Waterways Experiment Station Coastal Engineering Research Center as part of the Monitoring Completed Coastal Projects Program. This report summarizes data collected throughout the experiment. The purpose of this study was to provide actual field data to evaluate output from a numerical model, Regional Coastal Processes Wave Transformation Model, (RCPWAVE Computer program), which predicts waves propagating through a coastal region of irregular bathymetry. This report contains brief descriptions of the monitoring effort and equipment and provides collected wave information in graphic and tabular form. Statistical analysis of wave data will be provided in a future report.
