dc.description.abstract | For understanding characteristics of acoustic propagation in shallow water environment, reliable geoacoustic data such as bottom composition, topography, and sediment layer are necessary in theoretical and practical approach. As the full data acquisition, however, is limited in the field, it has applied to simplify the geological structures in most cases [1]. The simplification of the environment variable is limited on the analysis of the acoustic propagation and theoretical verification of the measured data in shallow water.The study area was Yellow Sea that it has a well-developed shallow continental shelf and especially strong tide. The seabed due to the strong tide has been formed various bed-form (ripple, sand wave and sand dune) along direction and strength of the tide [2]. Unlike water-sediment interface with flat bottom, the sand wave and sand dune have a strong influence on acoustic propagation, reflection and scattering.In this paper, we present the effects of low-frequency sound waves caused by sand wave zone with the acoustic transmission loss data measured in shallow waters.ta acquisition, however, is limited in the field, it has applied to simplify the geological structures in most cases [1].
