Abstract :
In this paper, a two dimensional simulation of acoustic wave propagation was evaluated to assess the dispersion of sound wave fronts in shallow waters. This simulation was used to survey three dimensional sound propagation effects in shallow water in Hormoz Strait. Sound wave propagation simulation is appropriate for wide range of modeling methods with different accuracy degrees. One of these methods which is based on finite difference method, is useful for describing seismic wave propagation in shallow waters. This paper focused on assessing the use of finite difference method in time domain propagation modeling and imaging wave frontpropagation using Matlab and FORTRAN. The results of this simulation showed that due to the vertical velocity change of the sound velocity, the waves were divided into two branches and ultimately the vortex generated the sound waves and the regions with high noise could be highlighted.
