Parametric characterization of surface wave data Conference Paper uri icon


  • There has been increasing interest on the part of practitioners and engineering researchers to develop better parametric characterizations of surface waves and their kinematics in an effort to reconcile field measurements and waves generated in model basin studies. The many nonlinear features of individual waves and the wave fields in localized regions observed in field studies, have raised further questions regarding our collective understanding of this natural phenomena. Better understanding and description of aspects, such as, wave forms, dispersion and general behavior in long and short crested seas are of great interest for science and engineering studies. Presently there is a variety of parameters that have been developed to characterize both the global and more detailed local scale phenomena. In this study the primary emphasis is placed on global scale characterization of the wave field. A dimensionless spectral peakedness parameter that relates measured data to a spectrum model selected by the designer is investigated. This parameter provides one measure of the appropriateness of the model selected to represent the data. Single and double peaked wave elevation spectrum models are used to illustrate the behavior of the dimensionless spectral peakedness parameter.
