Perhaps the most important and encouraging results of this PE workshop were that underwater acoustic parabolic equation (PE) models from both the 6.1 basic research modeling community and the 6.3 Navy operational modeling community were applied to the same set of test problems--each test problem designed to push the PE models to their limits--and each of the two communities' PE models did extremely well, given the requirements and constraints imposed by each community. The PE models developed by the 6.1 basic research modeling community were able to produce results for the test case problems that were benchmark accurate. This is a definite requirement, since the basic research community uses these models to identify, to isolate, and to understand the physical mechanisms involved in underwater acoustic propagation and scattering in highly complex underwater environments. The 6.3 Navy operational community is also interested in accurate model predictions, but the need for computational speed, portability, and the ability to run a computer in the field (micro or desk-top) is also of utmost importance-to the extent that trade-offs among accuracy, speed, and portability must be optimized. The results from this workshop demonstrate that the under water acoustic PE models used by both modeling communities are performing at their expected levels.
