Base Mine Lake (BML) is a pit lake used to store the Fluid Fine Tailings (FFT) generated by the oil sands industry, in the Athabasca region (northern Alberta, Canada). It is well studied to try understanding its evolution over time and to determine if an e ...

Turbulent mixing produced by breaking of internal waves plays an important role in setting the patterns of downwelling and upwelling of deep dense waters and thereby helps sustain the global deep ocean overturning circulation. A key parameter used to chara ...

Testing turbulence theories in the ocean: insights from state-of-the-art observations

Andrea Cimatoribus

During the last decade, environmental flows have been measured with a growing set of instruments, which can now offer relatively high resolution in space and time. This growing amount of data can analysed following a "statistical approach to turbulence", r ...

Transport and mixing in Lac Léman

David Andrew Barry, Ulrich Lemmin, Andrea Cimatoribus

Lake Geneva (Lac Léman) is the largest freshwater body in Western Europe. It is a deep peri-alpine lake whose importance stems from being not only an essential freshwater source in the region, but also a major tourist destination, a fishery and a waterway. ...

Typical near surface layer current patterns in Lake Geneva’s main basin (Grand Lac)

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Amir Mehdi Razmi

Poster Hall The Lake Geneva current field is controlled by a variable wind field and thermal stratification. Typical current patterns in the Grand Lac which is oriented roughly in the East-West direction were determined under real time wind conditions and ...

Heat flux modifications related to climate-induced warming of large European lakes

Alfred Johny Wüest, Martin Schmid

Within the last decades, the water temperature of several European lakes has risen. It is assumed that these temperature increases are due to a reconfiguration of the heat-balance components. This study explores the dominant modifications of heat exchange ...

Snow accumulation and melt patterns play a significant role in the water, energy, carbon, and nutrient cycles in the montane environments of the Western United States. Recent studies have illustrated that changes in the snow/rainfall apportionments and sno ...

Numerical simulations were carried out to examine gyre formation within open, wide lacustrine embayments. The present study was motivated by observed differences in gyre formation within two open and wide embayments (located at Vidy and Morges in Lake Gene ...

Phase Analysis of the Stretching Cycles of the Head of Unsteady Gravity Currents Developing over Smooth and Rough Beds

Mário Jorge Rodrigues Pereira Da Franca, Helena Isabel Dos Santos Nogueira, Claudia Adduce

Gravity currents are buoyancy driven flows occurring spontaneously in nature or resulting from human intervention. Examples of gravity currents in the water are oceanic fronts, resulting from differences in temperature and salinity, and turbidity currents ...

Energy and water conservation from air handling unit condensate in hot and humid climates

Dusan Licina

This study investigates the potential for energy and water sustainability in hot and humid climates by utilizing the condensate captured from large dedicated air handling units (AHUs) for pre-cooling outdoor air in another AHU and subsequently offsetting c ...
