Suspended sediments in Lake Geneva: Observations, settling behaviour and mechanisms in the Rhône River plume

David Andrew Barry, Ulrich Lemmin, Htet Kyi Wynn, Violaine Florette Piton, Valentin Kindschi

In estuaries and marine environments, primary particles are frequently transported as large flocculated particles. This study provides, for the first time, evidence of in situ flocculation in Lake Geneva, a glacier-fed freshwater lake on the Swiss/French b ...

Wintertime Coastal Upwelling in Lake Geneva: An Efficient Transport Process for Deepwater Renewal in a Large, Deep Lake

David Andrew Barry, Ulrich Lemmin, Andrea Cimatoribus, Rafael Sebastian Reiss

Combining field measurements, 3‐D numerical modeling, and Lagrangian particle tracking, we investigated wind‐driven, Ekman‐type coastal upwelling during the weakly stratified winter period 2017/2018 in Lake Geneva, Western Europe's largest lake (max. depth ...

Tracking Lagrangian transport in Lake Geneva: A 3D numerical modeling investigation

David Andrew Barry, Ulrich Lemmin, Andrea Cimatoribus

Lake Geneva, the largest freshwater lake in Western Europe, is subject to important environmental pressures from its densely populated shores and watershed. To maintain and improve water quality in this lake, as well as in other enclosed or semi‐enclosed b ...

Nonlinear dynamics of the near-shore boundary layer of a large lake (Lake Geneva)

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Andrea Cimatoribus

We examine near-shore and pelagic current variability in Lake Geneva, a large and deep lake in western Europe, using observations from several measurement locations and a three-dimensional numerical model for the period 2014-2016. Linear internal seiche mo ...

Sediment resuspension mechanisms and their contributions to high-turbidity events in a large lake

Damien Bouffard

High-resolution field data, collected during April to October of 2008–2009, were analyzed to investigate the quantitative contribution of sediment resuspension to high-turbidity events in central Lake Erie. Resuspension events were distinguished within hig ...

Optimizing the parameterization of deep mixing and internal seiches in one-dimensional hydrodynamic models: a case study with Simstrat v1.3

Alfred Johny Wüest, Damien Bouffard, Robert Vincent Schwefel, Adrien Gaudard, Carl Love Mikael Råman Vinnå, Martin Schmid

This paper presents an improvement of a one-dimensional lake hydrodynamic model (Simstrat) to characterize the vertical thermal structure of deep lakes. Using physically based arguments, we refine the transfer of wind energy to basin-scale internal waves ( ...

Bacteria-induced mixing in natural waters

Alfred Johny Wüest, Oscar Rodrigo Sepúlveda Steiner, Talia Ekin Tokyay Sinha

Swimming organisms can enhance mixing in their natural environments by creating eddies in their wake and by dragging water along. However, these mixing mechanisms are inefficient for microorganisms, because swimming-induced variations in velocity, temperat ...

Estimation of wave propagation velocity on a channel with smooth and rough bed

Anton Schleiss, Michael Pfister, Davide Wüthrich, Ioan Nistor

Natural hazards such as tsunamis, impulse waves and dam-break waves are rare, but extremely destructive. In recent times, more importance was given to structures that could withstand such events, however, uncertainties still exist in the estimation of wave ...

Signal analysis of an actively generated cavitation bubble in pressurized pipes for detection of wall stiffness drops

Anton Schleiss, Giovanni De Cesare, Mohamed Farhat, Fadi Hachem, Alexandre Jean Pachoud

Due to the increasing production of volatile new renewable energies as solar and wind, storage hydropower plants have to operate under harsh operation conditions in order to stabilize the electricity grid. As a result, highly transient water pressures occu ...
