The Interaction of Nonlinear Internal Waves with Coastal Topography and River Outflows.

Abstract

In this project we conducted analytical and numerical models of the interaction of nonlinear internal waves with coastal topography, and considered models of the evolution of river outflows. Analytical and numerical models of the evolution of nonlinear Kelvin waves showed that they could evolve to breaking along a front for a distance offshore comparable to The Rossby radius. It was found that in rotating systems the time to breaking was delayed when compared to the corresponding non-rotating case. The problem of the propagation of fronts and hydraulic jumps along boundaries in rotating fluids was formulated and solved with an approximate analytical solution and more complete numerical solutions. It was found that asymptotically the front tends to a wave of permanent form near the coast, with an incidence angle offshore which is a function of the amplitude of the front.
