Abstract An explanation is given for the propagation time of the well-known anomalous ultrasonic slow wave observed in water-saturated sand using a three-layer elastic model. The rapid increase of elastic properties of sand with depth causes conversion of near-grazing underwater acoustic waves into multiple coupled shear and compressional waves.
