Damping of water waves over porous bed
WebIn this paper, we study the viscous damping of waves on a stably stratified fluid over a porous elastic seabed. Using the linearised Navier-Stokes equations as the governing equations of motion, the newly derived solution describes the attenuation of a progressive surface wave on a two-layer stratification due to damping caused by WebThis study computed numerically wave damping passing over the porous seabed using a boundary element method. The fluid is assumed to be inviscid and incompressible, and …
