Numerical Analysis of Harbor Resonance Response in East Channel, Los Angeles Harbor.

Abstract

A hybrid finite-element numerical model was used to calculate harbor resonance, relative to that for existing conditions, for proposed non-Federal dredging adjacent to East Channel in the Port of Los Angeles. The numerical model yields convergent solutions for harbors of arbitrary shape and variable depth. The response of East Channel to long-period wave excitation was calculated over the 60- to 600-sec range for each plan. Wave-height amplification was similar at periods less than 200 sec; however, amplification of the fundamental mode of oscillation (near a period of 6 min for each plan) was significantly different.
