[1] Laboratory observations are presented showing the structure and dynamics of the turbulent bottom boundary layer beneath nonlinear internal waves (NLIWs) of depression shoaling upon sloping topography. The adverse pressure gradient beneath the shoaling waves causes the rear face to steepen, flow separation to occur, and wave-induced near-bottom vortices to suspend bed material. The resuspension is directly attributed to the near-bed viscous stress and to near-bed patches of elevated positive… 

Experimental investigation of sediment resuspension beneath internal solitary waves of depression

Internal solitary waves (ISWs) of depression are common features of coastal environments and believed to resuspend sediments where they shoal. In this study, the sediment resupension process

Boundary-layer-separation-driven vortex shedding beneath internal solitary waves of depression

Abstract We investigate global instability and vortex shedding in the separated laminar boundary layer beneath internal solitary waves (ISWs) of depression in a two-layer stratified fluid by

Assessing the relationship between bed shear stress estimates and observations of sediment resuspension in the ocean

We present observations from a three week field programme on the Tasman Eastern Continental Shelf designed to determine the mechanisms responsible for sediment resuspension when tidally-forced

Observations of Near-bed Stress beneath Nonlinear Internal Wave Trains in the Ocean

Observations of near-bed turbulence are reported under the forcing of mode-1 nonlinear internal waves of depression in the Browse Basin on Australia’s Northwest Shelf. These extreme events drive a

Sediment Resuspension Due to Near‐Bed Turbulent Effects: A Deep Sea Case Study on the Northwest Continental Slope of Western Australia

Sediment transport equations often consider a mean velocity threshold for the initiation of sediment motion and resuspension, ignoring event‐based turbulent bursting processes. However, laboratory

Internal waves are important physical phenomena on the continental shelf/slope. They are often very energetic, and their breaking provides an important dissipation and mixing mechanism, with

Bottom Boundary Layer Instabilities Induced By Nonlinear Internal Waves

Internal solitary waves (commonly referred to as ”nonlinear internal waves” due to the balance between nonlinearity and dispersion, with the intense nonlinearity represented by very strong

Turbulence observations of the nearshore wave bottom boundary layer

[1] Field observations of turbulence and sediment suspension in the nearshore wave bottom boundary layer obtained during the Duck94 field experiment on the North Carolina coast showed the generation

Sediment Resuspension and Mixing by Resonantly Generated Internal Solitary Waves

The observation of internal solitary waves (ISWs) propagating upstream along a strongly stratified bottom layer on the California shelf is reported. An increased concentration of particulates in the

Internal solitary waves of elevation advancing on a shoaling shelf

A sequence of three internal solitary waves of elevation were observed propagating shoreward along a near‐bottom density interface over Oregon's continental shelf. These waves are highly turbulent

Vortex shedding and sediment resuspension associated with the interaction of an internal solitary wave and the bottom boundary layer

In this note we present results on the interaction of fully nonlinear internal solitary waves with the oceanic bottom boundary layer. We show that for fully nonlinear solitary waves it is the

Large-Eddy Simulation of Sediment Transport: Currents over Ripples

A large-eddy simulation has been performed to study the detailed sediment dynamics that occur in channel flow over ripples. The code solves the Navier-Stokes equations and an advection-diffusion

Near-bed turbulence and bottom friction during SandyDuck97

[1] Remote acoustic measurements of turbulence intensity profiles are investigated as a function of wave energy and bedstate, from low energy vortex ripples to high energy flat bed. Outside the wave
