The propagation of sound in a laboratory-modeled, shallow water environment consisting of water overlying a thick layer of water-saturated sand was experimentally investigated. A hydrophone consisting of a small lead-titanate lead-zirconate cylinder was used as a receiver. A 304x117x95 cm fiberglass-encased wooden tank with a 10 cm layer of water overlying a 45 cm layer of water-saturated sand was used in this experiment. The receiver sensitivity and directionality were determined for frequencies from 10 kHz to 100 kHz. The ration of the speed of sound in the water-sand to that in water was 1.2 and the ratio of the densities was 2.05. The measured normal-incidence pressure reflection coefficient was within 12.8% of the predicted value. The measurements of pressure amplitude in the water as a function of depth were found to be in good agreement with normal mode theory for the first mode, but slight unexplained differences were observed for the sum of the first and second modes.
