Abstract:

The Parabolic Equation Model is a wave acoustics model designed for the computation of acoustic transmission loss as a function of range and depth in range dependent ocean environments. The elliptic reduced wave equation is approximated by a parabolic partial differential equation that can be numerically integrated by marching the solution forward in range. The model is primarily useful for predicting low frequency 200 Hz acoustic propagation of energy along waterborne paths. This report briefly describes the physics and mathematics of the model and documents a computer program developed at AESD. Individual routines are documented in an appendix. Environmental input routines must be supplied by the user and are not described in this report. Author
