Beschreibung
D-cascade: mathematical model and examples of the energy spectrum computation. I present briefly the mathematical model of dynamical cascade (D-cascade) formed in wave systems with moderate nonlinearity due to modulation instability (which is another name for the Benjamin-Feir instability). I demonstrate how to compute the shape the D-cascade energy spectrum taking as examples various types of water waves. Moderate nonlinearity means e.g. for surface water waves that wave steepness is of the order of 0.1 (cf.: in the wave turbulence theory it is of the order of 0.01).
