| The generation of the internal tide and the consequent generation of internal solitary waves is now well documented in many observations, and numerical simulations. This process, and the weakly nonlinear theories based on Korteweg-de Vries type models are here briefly reviewed and evaluated. For the most part these theories are based on a perception that the generation mechanisms involving the interaction of the barotropic tide with the continental shelf are essentially two-dimensional. However, because some satellite observations indicate that there are circumstances in which the generation process may instead be three-dimensional and associated with such topographic features as submarine canyons, we will present some preliminary results on the development of a Boussinesq-type system based on a novel modal decomposition technique to describe this three-dimensional process |
