Book Description
Design wave criteria are required in several offshore areas that feature depths sufficiently shallow to modify wave conditions incident on to them from deep water. Areas include Sable Island Bank, Beaufort Sea & parts of Queen Charlotte Strait. Study compares performance of 2 shallow water models to determine suitability for use in Canadian waters.
Nonlinear Parametric Wave Model Compared with Field Data
Author: Jose Luis Branco Seabra de MeloPublisher:
ISBN:
Category : Ocean waves
Languages : en
Pages : 78
Book Description
Wave spectra calculated using the Parameterized Nonlinear Wave Solution developed by Le Mehaute et al. (1984) are compared with field data acquired at Leadbetter beach, Santa Barbara, California. The parameterized solution satisfies the nonlinear free surface boundary conditions to a specified degree of accuracy and is expressed in terms of a converging truncated Fourier series. The wavenumber, surface profile and wave orbital velocities are determined by the wave height and wave period at the local depth of water. Spectral components are compared between the model results and field data. Good agreement is observed for waves corresponding to Ursell numbers rangers from 25 to 75. For large Ursell numbers (strong nonlinear effects) the parameterized model underestimates the data. Keywords: Nonlinear waves; Shallow water waves; Spectral analysis. (Theses).

A User's Guide to a Steady-state Shallow-water Directional Spectral Wave Model
Author: Jon M. HubertzPublisher:
ISBN:
Category : Ocean waves
Languages : en
Pages : 58
Book Description
This report describes the formulation and use of a directional spectral wave model which can be used in shallow water. The model simulates the transformation of a directional wave spectrum over an arbitrary two dimensional bathymetry allowing for the effects of atmospheric input, bottom friction, bottom percolation, nonlinear wave interaction, shoaling, refraction, and equilibrium range energy limitation. The user has the option to include or exclude these sources and sink terms in any combination desired. The formulation of each of these terms is summarized. A description of the computer code is provided including a summary of the purpose of each subroutine and the format for data input and output of results. A sample application is provided showing the transformation of a wave spectrum from deep to shallow water over a uniformly sloping bottom.

Book Description
This comprehensive and up-to-date volume contains 367 papers presented at the 29th International Conference on Coastal Engineering, held in Lisbon, Portugal, 19-24 September 2004. It is divided into five parts: waves; long waves, nearshore currents, and swash; sediment transport and morphology; coastal management, beach nourishment, and dredging; coastal structures. The contributions cover a broad range of topics including theory, numerical and physical modeling, field measurements, case studies, design, and management. Coastal Engineering 2004 provides engineers, scientists, and planners state-of-the-art information on coastal engineering and coastal processes.The proceedings have been selected for coverage in:
Waves in Oceanic and Coastal Waters
Author: Leo H. HolthuijsenPublisher: Cambridge University Press
ISBN: 1139462520
Category : Science
Languages : en
Pages : 9
Book Description
Waves in Oceanic and Coastal Waters describes the observation, analysis and prediction of wind-generated waves in the open ocean, in shelf seas, and in coastal regions with islands, channels, tidal flats and inlets, estuaries, fjords and lagoons. Most of this richly illustrated book is devoted to the physical aspects of waves. After introducing observation techniques for waves, both at sea and from space, the book defines the parameters that characterise waves. Using basic statistical and physical concepts, the author discusses the prediction of waves in oceanic and coastal waters, first in terms of generalised observations, and then in terms of the more theoretical framework of the spectral energy balance. He gives the results of established theories and also the direction in which research is developing. The book ends with a description of SWAN (Simulating Waves Nearshore), the preferred computer model of the engineering community for predicting waves in coastal waters.
Twenty-Second Symposium on Naval Hydrodynamics

ISBN: 0309065372
Category : Science
Languages : en
Pages : 1039
Book Description
The Twenty-Second Symposium on Naval Hydrodynamics was held in Washington, D.C., from August 9-14, 1998. It coincided with the 100th anniversary of the David Taylor Model Basin. This international symposium was organized jointly by the Office of Naval Research (Mechanics and Energy Conversion S&T Division), the National Research Council (Naval Studies Board), and the Naval Surface Warfare Center, Carderock Division (David Taylor Model Basin). This biennial symposium promotes the technical exchange of naval research developments of common interest to all the countries of the world. The forum encourages both formal and informal discussion of the presented papers, and the occasion provides an opportunity for direct communication between international peers.
