In this project we conduct experimental and numerical investigations on the attenuation mechanisms of surface waves in poroelastic materials. Viscous dissipation effects are modelled in the framework of Biot's theory. The experiments are performed using a shock tube technique. Quantitative agreement between the experimental data and the numerical predictions is found. Numerically, saturation effects are also studied. Significant dependence of the attenuation coefficients on the liquid saturation is found for the surface modes.
