The peculiarities of Rayleigh waves propagating along free surface of saturated porous medium and Stoneley waves propagating along the boundary of saturated porous medium and liquid are investigated. The dispersion relations are obtained. The frequency dependencies of phase velocity, linear decrement of attenuation and coefficients exhibiting damping of amplitude with depth for monochromatic waves are studied. The pattern of deformation of near-surface area during surface wave propagation is considered.
