Shallow Water Propagation Methods and 3-D Effects

Abstract

The high level goal of this proposal is accurate and efficient determination of acoustic predictions in 3-D shallow water waveguides with complex features that are characteristic of coastal and Arctic regions. One focus is to advance split-step Pad~ parabolic equation methods to include capabilities for anisotropic and poro-elastic ice regions and sediments. Another is to develop split-step F"ourier PEs for 3-D problems in elastic, poro-elastic, and multiple-component sediments. A final thrust is to find the sensitivity of" acoustic quantities to variations of parameters in 3-D models of frontal features. The proposed research will be carried out in reg"ular collaboration with Dr. Michael D. Collins (NRL) and Dr. Y.-T. Lin (WHOI).
