Wave Propagation Prediction Over a Thin Elastic Sediment and Rock Basement

In this paper, a model which computes both compressional-and shear-wave transmissions and reflections through a sediment layer is utilized to formulate a single bottom reflection coefficient which is shown to successfully predict resonance effects due to shear-wave conversion in various types of sediment. Comparisons of model results to published bottom loss curves are presented. Propagation results obtained by implementing the bottom loss calculations in a normal mode model are compared to other model results and measured data sets over a variety of bottom types.
