Numerical simulations of stratified fluid flow over topography near resonance

We use a high-resolution spectral numerical scheme to solve the two-dimensional equations of motion for the flow of a uniformly stratified Boussinesq fluid over isolated bottom topography in a channel of finite depth. The focus is on conditions such that the flow is near linear resonance. The results are compared with the analytic solutions as well as experimental tank results. We also analyze the approach to breaking that occurs downstream of the topography near resonance.
