WebThis article presents results concerning the excess kinetic and potential energies for exact nonlinear water waves. In particular, it is proven, for periodic travelling irrotational … WebRogue waves are open-water phenomena, in which winds, currents, nonlinear phenomena such as solitons, and other circumstances cause a wave to briefly form that is far larger than the "average" large wave (the significant wave height or "SWH") of that time and place. The basic underlying physics that makes phenomena such as rogue waves possible is that …

WebSolitary Waves. Solitary waves are another class of non-linear waves, and they have very interesting properties. They propagate without change of shape, and two solitons can cross without interaction. The first soliton was discovered by John Scott Russell (1808-1882), who followed a solitary wave generated by a boat in Edinburgh's Union Canal ... Webnetic energy density is always negative, whereas the excess potential energy density is always positive, for nonlinear water waves which are periodic, travelling and irrotational. A characterisation of the total excess energy density as a weighted mean of the kinetic energy along the wave surface profile is also constructed. David Henry ...
