Field observation of wave damping by fluid mud

Extensive mud deposits are found off Cassino Beach, Brazil. The wave damping over the muddy bottom was studied using field measurements. By applying a technique of spectral analysis we showed that the wave attenuation occurred differently throughout the wave spectra. Field measurements revealed that the maximum wave energy dissipation took...

Viscous dissipation of monochromatic waves in still water of finite constant depth in a channel of finite width

Energy dissipation of water waves propagating in a smooth-walled channel of finite water depth and finite width is mainly due to viscous effects. Providing that the wave length is sufficiently large compared to the water depth and a finite channel width, wave energy is principally dissipated in the boundary layers on the bed and on the walls....
