Abstract: The Los Angeles-Long Beach Harbors physical model for harbor resonance was used to investigate the effects of the Operations, Facilities, and Infrastructure (OFI), Scheme B, 2020 Plan on long waves (periods 30-500 sec) at existing and proposed berth locations. Phases I and II were studied. Monochromatic and irregular long waves were programmed for the 59.5-m (195-ft) segmented wave generator which produced a variable amplitude wave front Long period wave heights were measured at 87 gauge locations for existing and plan conditions. Long-period wave spectra represented winter storms from the west and waves from the south (more typical of summer and early fall). Wave measurements of harbor resonance indicated that for Los Angeles Harbor, Phases I and II, most existing harbor locations experienced reduction in wave height amplification factors (calculated relative to the ocean wave height), with only a few locations indicating slight increases, and these for relatively low amplification values. Fish Harbor and Pier 300 showed significant reduction in wave amplification. Proposed harbor berths on the new Island landful showed good response characteristics. Maximum responses periods tended to be greater than 200 sec, where ship motion response is less significant. NOTE: This file is large. Allow your browser several minutes to download the file.
