An experimental investigation of low-mode internal wave generation and interaction with shelf topography
Abstract/Contents
- Abstract
- A set of laboratory experiments were performed to examine the generation of low-mode internal waves and their interaction with an idealized continental shelf/slope topography. A tunable wave generator was utilized to produce a high-quality mode-1 wave field in a linearly stratified fluid. Modal analysis results indicate the generation of a high-quality mode-1 wave which transforms into higher modes as the wave interacts with the topography. The wave-slope interactions produced a range of responses including the formation of upslope-surging internal boluses that propagated across the shelf flat. Bolus formation was primarily dependent on the wave Froude number and the ratio of the topographic slope to the internal wave characteristic slope. Boundary layer thickness and finite water depth are also shown to effect bolus formation and propagation. These results compare well to the two-dimensional numerical simulations of Venayagamoorthy and Fringer (2007) with some deviations which may be attributable to the effects of the three-dimensionality of these experiments. Comparisons are also made to experiments (Moore et al., 2015, JFM in review) performed in a two-layer stratification where internal boluses were observed.
