Directional spreading model in a wave channel: Wave propagation and wave breaking

► Directional spreading analysis of the wave propagation under conditions of wave breaking on complex bathymetries. ► Special attention was made to the end part of the wave breaking process. ► The directional analysis may serve as an index for wave breaking turbulence. ► Study in detail the wave breaking process throughout the surf section. ► Special innovative wave data analysis on a 2D wave channel.
