LONG BEACH HARBOR NUMERICAL ANALYSIS OF HARBOR OSCILLATIONS. REPORT 1. EXISTING CONDITIONS AND PROPOSED IMPROVEMENTS

A hybrid finite element numerical model was used to calculate harbor resonance for existing conditions and proposed improvements of Los Angeles and Long Beach Harbors. The numerical model calculates harbor oscillation for harbors of arbitrary shape and variable depth. Ten finite element numerical grids were used to calculate the response of the harbors complex for incident waves with periods from 1 to 10 min. Calculations of the model for existing conditions of the harbors were shown to be in good agreement with prototype measurements. The numerical model calculations indicate that resonant oscillations in existing harbor facilities will not be radically altered by the proposed modifications of the harbors complex. The resonant oscillations are, in general, somewhat smaller for the modified conditions of the harbors complex than for existing conditions. (Author)
