Numerical Analysis of Harbor Oscillations for Barbers Point Deep-Draft Harbor.

Abstract

A hybrid finite element numerical model was used to calculate harbor resonance for a proposed deep-draft harbor at Barbers Point, Oahu, Hawaii. The numerical model calculates forced harbor oscillations for harbors of arbitrary shape and variable depth. A numerical finite element grid with 2,334 elements was used to compute wave-height amplification factors and normalized maximum current velocities associated with the harbor's response to incident waves from 20 sec to 27 min. The numerical model calculations identified resonant oscillations of the proposed deep-draft harbor. Based on model results, inferences as to potential ship movement, navigation problems, and harbor circulation were made for the resonant oscillations. (Author)
