Experiments with withdrawal-induced resonant internal waves
… with application on the lake. The generation of internal waves in a rectangular tank by a pump with sinusoidally modulated flow has been investigated via laboratory experiments. Theory appropriate to internal waves in two layer systems has been presented with an extension to deal with the effect …

Cooling and internal waves on the Continental Shelf
… results from this balance. Solutions for linear internal waves are found for a wedge-shaped bathymetry with bottom friction. Bottom friction is capable of entirely dissipating the waves before they reach the coast, and waves traveling obliquely offshore are reflected back to the coast from a …

Interpretation of equatorial current meter data as internal waves
… frequency-wavenumber energy spectra for internal waves (GM72, GM75, GM79). The GM internal wave models are horizontally isotropic, vertically symmetric, purely propagating, and universal in both time and space. This set of properties effectively eliminates all the interesting physics, …

The influence of topography on steady currents and internal waves
… concerns the nonlinear effects of shoaling internal gravity waves. For normal incidence on a two-dimensional beach the Reynolds stresses produced by the fundamental wave motion are shown to force a mean Eulerian current which is equal hut opposite in sense to the Stokes drift. This causes …

Physics of diurnal warm layers : turbulence, internal waves, and lateral mixing
… for the enhanced TKE dissipation. High-frequency internal waves (𝜔 ≫ 𝑓) were observed in the upper ocean during the daytime within the DWL. Internal waves are able to transfer energy from the deep ocean into the DWL through the unstratified remnant mixed layer, which is the intervening layer …

Interference and Transmission of locally forced internal waves in non-uniform stratifications
… destructive interference on the transmission of internal waves that propagate through non-uniform stratifications. Such studies have been performed for internal waves that are spatiotemporally harmonic. To understand the effect of spatiotemporal localization, this thesis presents a theoretical …

The effect of internal waves on long range acoustic propagation in the ocean
The acoustic-internal wave interaction in an acoustic waveguide is investigated using wave techniques. Refractive index fluctuations due to the vertical displacements of the internal waves create an inhomogeneous waveguide. The analysis uses weak scattering theory based upon the Rytov perturbation …

Laboratory and analytical modeling of internal waves in uniform and non-uniform stratifications
Internal gravity waves are propagating disturbances in a stably stratified fluid. Ubiquitous in geophysical systems, they have significant impact on both fundamental processes and engineering applications. In the ocean, for example, internal waves are a significant means of tidal dissipation, …

Interaction of high frequency internal waves and the boundary layer on the continental shelf
… propagating packets of high frequency first mode internal waves are common on the continental shelf when the water column is stratified and may induce large fluctuations in near bottom velocity. Simple theoretical considerations here lead to an approximate method for estimating those quantities of …
