Deepwater Renewal in a Large, Deep Lake (Lake Geneva): Identifying and Quantifying Winter Cooling Processes Using Heat Budget Decomposition

Ulrich Lemmin, David Andrew Barry, François Mettra, Rafael Sebastian Reiss, Naifu Peng

Wintertime deepwater renewal, which is important for heat-oxygen-nutrient exchange in lakes, is traditionally considered to be mainly driven by 1D vertical convective cooling. However, differential cooling between shallow and deep waters can produce densit ...

Spatial correlations in bed load transport: Evidence, importance, and modeling

Christophe Ancey, François Mettra, Joris Heyman, Hongbo Ma

This article examines the spatial {dynamics of bed load particles} in water. We focus particularly on the fluctuations of particle activity, which is defined as the number of moving particles per unit bed {length}. Based on a stochastic model recently prop ...

Statistics of bedload transport over steep slopes: Separation of time scales and collective motion

Christophe Ancey, François Mettra, Joris Heyman, Hongbo Ma

Steep slope streams show large fluctuations of sediment discharge across several time scales. These fluctuations may be inherent to the internal dynamics of the sediment transport process. A probabilistic framework thus seems appropriate to analyze such a ...
