Surface waves at an interface between a saturated porous medium and a liquid are investigated. Existence and peculiarities of surface wave propagation are revealed. Three types of surface waves are proven to be possible: true Stonely surface wave propagating almost without dispersion, leaky slow pseudo-Stonely wave, and leaky generalized Rayleigh wave. True Stonely and generalized Rayleigh waves correspond to those waves, which exist at a free interface of a saturated porous medium with vacuum.
