the generation of capillary-gravity solitary waves by a surface pressure forcing

a weakly nonlinear model is used to study capillary-gravity waves generated by a traveling localized surface pressure distribution. the weakly nonlinear model is a truncation of the potential flow equations in deep water, and includes cubic nonlinear terms. numerically, solitary waves are shown to be generated by a near-monochromatic, subcritical forcing. the presence of these solitary waves is predicted using a forced nonlinear schrödinger equation.
