dc.description.abstract	Recent experimental results reveal acoustic penetration into sandy sediments at grazing angles below the critical angle. We have been investigating a mechanism for subcritical penetration based on scattering at a rough water-sediment interface. Using perturbation theory, a numerically tractable three-dimensional model has been developed for simulating experiments. Data-model comparisons show that interface roughness is a viable 11)pothesis for the observed subcritical penetration.
