A Coupled-Mode, phase-resolving model for the transformation of wave spectrum over steep 3D topography. A parallel-architecture implementation
The problem of transformation of the directional spectrum of an incident wave system over a region of strongly varying three-dimensional bottom topography is studied, in the context of linear theory. The Consistent Coupled-Mode Model (Athanassoulis and Belibassakis 1999, Belibassakis et al 2001) is...
