Wave Conditions for Proposed Harbor Development in Los Angeles Outer Harbor, Los Angeles, California, Supplemental Tests. Coastal Model Investigation

Abstract : A 1:100 scale (undistorted) hydraulic model of Los Angeles Outer Harbor, California, was used to investigate short-period storm and subsequent wave conditions for proposed harbor development located near the Angel's Gate entrance. The model reproduced the proposed harbor expansion, Angel's Gate entrance, portions of the generation of the existing breakwaters, and sufficient bathymetry in San Pedro Bay to permit generation of required test waves. The model was reactivated to determine the optimum plan for protection of the south mooring area (from locally generated waves in the harbor's complex) if the adjacent Port of Long Beach and/or the Pactex landfills are not constructed initially. A 80-ft-long electro-hydraulic, unidirectional, spectral wave generator and an automated data acquisition and control system were used in model operation.
