Solitary Waves, Singularity Formation and the Existence of Sand Bars


Abstract: This lecture has several objectives. First is to acquaint students with the history of solitons and soliton mathematics. Second is to describe some interesting open questions arising from this theory, and some recent progress. Lastly, we show how these ideas can be used in very practical modelling situations. The principal example will be concerned with problems arising in oceanography. A model for the interaction of surface or internal wave motion and bottom sediment will be described and shown to provide a useful tool for the analysis of problems arising in coastal engineering.
