Abstract:

To develop exact numerical methods that can be used to study the propagation of acoustic energy in shallow water. Exact in this contexts means that the methods place no restrictions on the underlying physics of the environment. 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.
