LES is a simulation technique widely used in the atmospheric science and engineering communities to study the detailed dynamics of flows. It is less widely used in the oceanographic community. LES is a valuable tool for modeling the dynamics of flows on shallow continental shelves. The capabilities of LES for such studies will be described. Some results from the application of LES to typical flows, such as wind stress driven flow with surface gravity waves in a homogenous water column, tidal flow with convection and wind stress driven flow with surface gravity waves in a stably stratified water column will be presented. The limitiations, some real and some imagined, of LES for ocean flows will be discused. Finally, expectations for the increase in the capability of LES for such flows in the near future will be presented.

Dr. Grosch earned M.E., M.S., and Ph.D. degrees from the Stevens Institute of Technology. He came to Old Dominion University in 1973 as a Samuel L. and Fay M. Slover Professor of Oceanography. Since his graduate work at Stevens Institute of Technology, he has held research and teaching positions at various institutions including Stevens Institute of Technology, Columbia University, Pratt Institute, and the University of Reading, U.K. While at Pratt Institute, he was chair of the Department of Computer Science and director of the Computer Center. In 1989, he was a Royal Society Guest Research Fellow at the University of Cambridge, U.K. His expertise includes fluid dynamics, boundary layers, stability, and computational fluid dynamics. Dr. Grosch's current research is focused on Langmuir circulation and turbulence on continental shelves.
