Abstract

A linear analytic solution for periodic water waves passing over a deformable bottom is presented. The solution assumes water of constant depth underlain by a perfectly elastic soil of infinite depth with a shear modulus representative of a soft marine sediment. Soil stresses and displacements along with the related water wave kinematics are obtained. In particular comparisons of wave length, bottom pressure and water particle velocities calculated by this theory and the well-known rigid bottom wave theory are made showing the effect of a range of soil shear moduli.
