Numerical Studies of Acoustic Propagation in Shallow Water

Abstract

The long-term goal is to develop "exact" numerical methods and visualization techniques that can be used to study the propagation of acoustic energy in shallow water in the time domain. Exact in this contexts means the methods place no restrictions on the underlying physics of the environment. The objectives are to: develop new, and enhance existing, numerical methods; to establish the accuracy, robustness, flexibility, and tractability of these methods; and to apply these methods to meaningful practical problems. To create a robust software suite for the application of the methods and to develop techniques for visualizing the propagation of scalar and vector fields in complex environments.
