Abstract : This report summarizes the results of research carried out during 1981 at Applied Research Laboratories, The University of Texas at Austine (ARL:UT), on acoustic bottom interaction in a range variable environment. The major topic is adiabatic normal mode modeling of range variable environments involving slopes or lateral variation. In particular the study of slope propagation is extended to consider sediment type, sediment attenuation gradients, and analysis of energy partitioning, and a reexamination of slope angle effects. The study of lateral variability considers an absorbing patch problem and its relation to province descriptions of range variable environments. The sensitivity of propagation over slopes to lateral variation of sediment type is also considered. (Author)
