Book Description
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.

Los Angeles Harbor Numerical Analysis of Harbor Oscillations

Publisher:
ISBN:
Category : Harbors
Languages : en
Pages : 236
Book Description
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 greatly altered by the proposed modifications of the harbors complex. The largest oscillation in the proposed LNG slip and general cargo terminal created by the Terminal Island landfill occurred at a wave period of 258 sec. The seaward side of the Terminal Island landfill did not exhibit significant resonant oscillations for incident waves with periods from 1 to 10 min. (Author).

Pages : 68
Book Description
Abstract: "An investigation was undertaken to evaluate numerical models that can be used to predict harbor response to long-period wave excitation for both conventional harbors with deep drafts and artificial offshore ports in deep water. Numerical models using finite difference, hybrid finite element, and Lee's method solutions are discussed and compared with analytical solutions, hydraulic model data, and prototype field data. The hybrid finite element method of solution is shown to adequately predict periods of resonant peaks and modal water-surface elevation patterns in conventional and offshore harbors. Computational time requirements of this numerical model are shown to be sufficiciently low to make resonant response calculations economically feasible for a wide range of incident wave periods. Use of the hybrid finite element method to evaluate deep draft harbor design or modification and to aid hydraulic model studies of harbor oscillations is discussed."
