Transmission Loss Variability in Shallow Water

Abstract

Bathymetry, sediment type and sediment thickness information is required to explain the variability of transmission loss in shallow water. Bathymetry and sediment charts may indicate uniform sediment type and relatively uniform bathymetry in shallow water. This uniformity leads to transmission loss estimates with little, if any spatial variability. Incorporating sediment thickness into model predictions explains much of the variability which is observed in experiments. Data and model results are presented.
