WebThe generation and propagation of waves in shallow water is computed by SWAN, which is able to mimic random, short-crested waves in the open ocean and in shallow water regions. The key processes incorporated in SWAN are wave-wave interactions, wave refraction, and wave dissipation, that includes bottom friction [35] and wave breaking [36]. WebUnder spectral wave conditions, wave energy within a model canopy array is dissipated at a greater rate among the shorter-period wave components. These observations are consistent with previous observations of how wave energy is dissipated by the bottom roughness of a coral reef. (Show Context) Citation Context
