The degeneration of internal waves in lakes with sloping topography
In a laboratory study, we quantified the temporal energy flux associated with the degeneration of basin-scale internal waves in closed basins. The system is two-layer stratified and subjected to aExpand

A diapycnal diffusivity model for stratified environmental flows
The vertical diffusivity of density, K-rho, regulates ocean circulation, climate and coastal water quality. K-rho is difficult to measure and model in these stratified turbulent flows, resulting inExpand

High‐frequency internal waves in large stratified lakes
Observations are presented from Lake Biwa and Lake Kinneret showing the ubiquitous and often periodic nature of high-frequency internal waves in large stratified lakes. In both lakes, high-frequencyExpand

Breaking of shoaling internal solitary waves
The breaking of fully nonlinear internal solitary waves of depression shoaling upon a uniformly sloping boundary in a smoothed two-layer density field was investigated using high-resolutionExpand

Vertical mixing and weak stratification over zebra mussel colonies in western Lake Erie
Zebra mussels (Dreissena polymorpha) are an invasive species that have been implicated in the reduction of algae stocks in the near-shore environment of western Lake Erie. To determine theirExpand

Spatial-Dynamic Modeling of Algal Biomass in Lake Erie: Relative Impacts of Dreissenid Mussels and Nutrient Loads
Over the past several decades, reductions in phytoplankton stocks and increased water clarity in Lake Erie have resulted from phosphorus load abatement and the introduction of zebra DreissenaExpand

Factors affecting the development and dynamics of hypoxia in a large shallow stratified lake: Hourly to seasonal patterns
depletion (e.g., � 0.7 to þ0.3 mg L � 1 d � 1 ) were examined in a field study conducted in the western part of the central basin of Lake Erie in 2008 and 2009. Data were obtained from a spatialExpand

The energetics of large-scale internal wave degeneration in lakes
Field observations in lakes, where the effects of the Earth's rotation can be neglected, suggest that the basin-scale internal wave field may be decomposed into a standing seiche, a progressiveExpand

A two-dimensional ecological model of Lake Erie: Application to estimate dreissenid impacts on large lake plankton populations
We constructed a complex ecological model of Lake Erie, EcoLE, based on a two-dimensional hydrodynamic and water quality model (CE-QUAL-W2). We used data from 1997 to calibrate the model, and dataExpand

Flow separation and resuspension beneath shoaling nonlinear internal waves
[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 slopingExpand
