WebSea is a term used to describe the mixture of waves often observed from ships. Seas may include ripples, chop, wind waves, storm waves, and swells. Seas are characterized by waves of differing heights coming from many directions (Fig. 4.7). Swells are waves that have obtained enough energy to travel beyond their generation area or fetch. WebJul 13, 2024 · The model applies the phenomena of wave generation due to wind action, nonlinear wave interaction, refraction as well as the dissipative process caused by surface white-capping. The multi sequential Euler explicit method was used for the discretization of the temporal term and the ‘upwind’ numerical scheme for the convective flux term.
