| Abstract: | This study is devoted to the interaction between water surface waves and a thin layer of viscoelastic mud on the bot-tom.On the assumption that the mud layer is comparable in thickness with the wave boundary layer and is much smaller than the wavelength,a two-layer Stokes boundary layer model is adopted to determine the mud motions under the waves.Analytical expressions are derived for the near-bottomwater and mud velocity fields,surface wave-damping rate,and in-terface wave amplitude and phase lag.Examined in particular is how these kinematic quantities may depend on the vis-cous and elastic properties of the mud. |
