Solitary Waves and Sill Flows

Abstract

Our goal is to elucidate the fluid dynamical processes associated with stratified flow over topography including the establishment of such flows, effects due to strong forcing and the generation of internal solitary waves. The key scientific objectives are (1) to determine the mechanisms responsible for streamline splitting and the role played by entrainment in forming a weakly stratified wedge of nearly stationary fluid over an obstacle as the flow adjusts to changing barotropic forcing, (2) to examine the detailed structure of instabilities in steeply inclined shear flows in the light of recent laboratory studies, (3) to describe the mechanism responsible for generation, trapping and release of internal solitary waves above an obstacle.
