Modelling of Wave Propagation in Shallow Water Environment

Abstract

PlaneRay, an acoustic underwater propagation model based on ray tracing and plane- wave reection coecients, has been used to model wave propagation in shallow water environments. The program has emulated a seismic vessel towing a source-receiver setup and represented the shape of the sea oor as time responses plotted for a xed source- receiver distance over an increasing source range. The eects of the water's sound speed prole and the sea oor's topography have been studied in detail, and the program's robustness and capability to handle these problems have been discussed and found sat- isfying.
