ENVELOPE, PHASE, AND NARROW-BAND MODELS OF SEAA WAVES

A comparison is made of the Rice-Dugundji and the Crandall-Mark narrow band representations. Certain inherent constraints implied by these representations such as criteria regarding the selection of characteristic frequencies, and whether such representations permit generalization or extensions to nonlinear waves are explored. The possibility of extending th RD representation to nonlinear waves is considered and demonstrated with a simple conceptual model. Apparent advantages and or disadvantages of such an approach are discussed. The applicability of the narrow-band representation to nonlinear waves is explored in terms of a simple model, which is correct to zero-order in wave directionality and spectral bandwidth, and to first-order in wave steepness.
