WebAug 19, 2024 · Gravity-capillary water waves are surface waves resulting from the balance of the potential energy of gravity forces and surface tension with the kinetic energy of a water column. As a result of body (volume) and interface (surface) contributions, their velocity is isotropic but inherently strongly dispersive and dependent on the water depth. WebThese asymmetric solitary waves have a multi-packet structure and appear via spontaneous symmetry-breaking bifurcations. We study in detail the stability properties of both symmetric and asymmetric solitary waves subject to longitudinal perturbations. Some moderate-amplitude symmetric solitary waves are found to be stable.
