Abstract
Wave propagation in seabeds is modeled by the propagator matrix derived from the Biot theory of anisotropic poroelastic media. The theoretical calculations are compared with measurements of wave‐induced pore pressure distributions in sand beds in wave tanks as well as in the field. It was found that a strong coupling between the shear waves and the two compressional waves exists in anisotropic beds which is absent in isotropic beds. The intrinsic coupling in the anisotropic beds is responsible for strong wave attenuation and wave reflection. [Work sponsored by ONR, Code 425UA].
