[1] A numerical model was developed for the prediction of the density stratification of lakes and reservoirs. It combines a buoyancy-extended k-epsilon model with a seiche excitation and damping model to predict the diffusivity below the surface mixed laye ...
The dissipation rate of turbulent kinetic energy per unit mass, epsilon, vertical eddy diffusivity, K-z, and the rate of dissipation of temperature variance, X, are estimated over the sloping sides of Lake Geneva both far from and near the bed, using tempe ...

Double-diffusive staircases with a total of 230-350 mixed layers and sharp interfaces were observed in nine microstructure temperature profiles measured during February 2004 in Lake Kivu. The presence of these staircases at depths. 120 m indicates that dia ...
This study discusses the occurrence and environmental risk associated with a micropollutant plume originating from the direct discharge of treated wastewater into the Vidy Bay of Lake Geneva, Switzerland. The temporal variations and spatial extent of the p ...
[1] Vertical overturns, produced by turbulence in density-stratified lakes and oceans, are often quantified by the Thorpe scale, L-T. The correlation between L-T and the Ozmidov (energy-containing) scale can be used to estimate rates of turbulent dissipati ...
Eutrophication of various lakes on the Swiss Plateau was targeted in the 1980s by reducing external nutrient loading and installing aeration/oxygenation systems. For five eutrophic lakes, three of which have been artificially oxygenated and aerated for alm ...
The river inflow in a natural lake with important suspended sediment load during floods, can impact water quality by mobilizing dissolved matters like phosphorous from deep to surface waters. Generally due to thermal stratification in prealpine lakes, the ...
Lake Kivu is one of the large African Rift lakes situated between the Democratic Republic of the Congo and Rwanda. In its permanently stratified hypolimnion, unusually high methane concentrations have increased further in recent decades. Because methanogen ...
