Nonlinear Modulational Instabililty of the Stokes Waves in 2D Full Water Waves
نویسندگان
چکیده
The well-known Stokes waves refer to periodic traveling under the gravity at free surface of a two dimensional full water wave system. In this paper, we prove that small-amplitude with infinite depth are nonlinearly unstable long-wave perturbations. Our approach is based on modulational approximation system and instability mechanism focusing cubic nonlinear Schrödinger equation.

Analysis of random nonlinear water waves: the Stokes–Woodward technique
A generalization of the Woodward's theorem is applied to the case of random signals jointly modulated in amplitude and frequency. This yields the signal spectrum and a rather robust estimate of the bispectrum. Furthermore, higher order statistics that quantify the amount of energy in the signal due to nonlinearities, e.g., wave–wave interaction in the case of water waves, can be inferred. Consi...

متن کاملModulational instability and rogue waves in shallow water models
It is now well known that the focussing nonlinear Schrödinger equation allows plane waves to be modulationally unstable, and at the same time supports breather solutions which are often invoked as models for rogue waves. This suggests a direct connection between modulation instability and the existence of rogue waves. In this chapter we review this connection for a suite of long wave models, su...
