On the Nature of Turbulence in a Stratified Fluid. Part I: The Energetics of Mixing
Abstract The definition of the flux Richardson number Rf is generalized to be the ratio of the turbulent buoyancy flux b to the net turbulent mechanical energy m available from all sources. ForExpand

The degeneration of large-scale interfacial gravity waves in lakes
Mechanisms for the degeneration of large-scale interfacial gravity waves are identified for lakes in which the effects of the Earth's rotation can be neglected. By assuming a simple two-layer modelExpand

Modeling basin‐scale internal waves in a stratified lake
Basin-scale internal waves provide the driving forces for vertical and horizontal fluxes in a stratified lake below the wind-mixed layer. Thus, correct modeling of lake mixing and transport requiresExpand

Unsteady natural convection in a rectangular cavity
The problem of transient natural convection in a cavity of aspect ratio A [les ] 1 with differentially heated end walls is considered. Scale analysis is used to show that a number of initial flowExpand

Structure of bubble plumes in linearly stratified environments
Bubble plumes in a linearly stratified ambient fluid are studied. Four well-defined flow regions were observed: an upward-moving bubble core, an inner plume consisting of a mixture of bubbles andExpand

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

On the nature of turbulence in a stratified fluid
Abstract A strong debate has continued for a number of years over the magnitude of the ratio of the buoyancy flux b to the rate of production of turbulent kinetic energy from the mean velocity sheer.Expand

Convective motions in the sidearm of a small reservoir
We present observations of the diurnal formation of horizontal temperature gradients in the surface waters of a sidearm of a small water supply reservoir at a time during summer when radiativeExpand

One- and three-dimensional biogeochemical simulations of two differing reservoirs
Abstract A one-dimensional hydrodynamic model was coupled to an aquatic ecological model and applied to two differing reservoirs with one set of parameters. Simulations over 2 years of small (area=5Expand
