Modulational Instabilities and Breaking Strength for Deep-Water Wave Groups

Galchenko, Alina; Babanin, Alexander V; Chalikov, Dmitry; Young, Ian; Hsu, Tai-Wen


Progression of nonlinear wave groups to breaking was studied numerically and experimentally. Evolution of such wave group parameters as a function of distance to breaking andmodulation depth-the height ratio of the highest and the lowest waves in the group-was described. Numerical model results demonstrated good agreement with experimental results in describing the behavior of the distance to breaking and modulation depth as functions of initial wave steepness. It was shown that energy loss...[Show more]
