Overview: Uses fully nonlinear hydrodynamic numerical models to discuss rogue waves.Presents statistics data, analysis of the wave groups and the role of different factors like resonance in the formation and dy.Extreme, freak or rogue waves are produced by a number of physical mechanisms that focus the water-wave energy into a small area, due to wave instability, chaotic behaviour, dispersion (frequency modulation), refraction (presence of variable currents or bottom topography), soliton interactions, etc. ..During the past thirty years a number of physical models of the rogue wave phenomenon
