Experimental modeling of fine sediment routing: SEDMIX device with thrusters
Giovanni De Cesare, Azin Amini, Montana Marshall
Reservoir sedimentation is a key challenge for storage sustainability because it causes volume loss, affecting hydropower production capacity, dam safety, and flood management. A preliminary EPFL study proposed and studied an innovative device (called SEDM ...
CRC Press/Balkema2023Characterization of Thruster-Induced Turbulence for Fine Sediment Suspension
Giovanni De Cesare, Azin Amini, Montana Marshall, Andre Luis Stakowian
Reservoir sedimentation is a key challenge for storage sustainability because it causes volume loss, affecting hydropower production capacity, dam safety, and flood management. A preliminary EPFL study proposed and studied an innovative device (called SEDM ...
2023p Spatio-temporal deposition profile of an experimentally produced turbidity current with a continuous suspension supply
Giovanni De Cesare, Shun Nomura
A turbidity current is a turbulent, particle-laden gravity current that is driven by density differences resulting from the presence of suspended sediment particles. The current travels downslope, bearing a large amount of sediment over a great distance, a ...
IRTCES2022Do Antidune Trains Undergo Morphological Changes When These Bedforms Migrate Upstream?
Upstream migrating antidunes develop in streams under supercritical flow conditions. These bedforms are often organised in trains (i.e. sequences of well-developed antidunes). In shallow flows over coarse sediments, the dynamics of a single antidune can be ...
IAHR International Association for Hydro-Environment Engineering and Research2022Quasi-stationary flow structure in turbidity currents
Giovanni De Cesare, Shun Nomura
A turbidity current is a particle-laden current driven by density differences due to suspended sediment particles. Turbidity currents can transport large amounts of sediment down slopes over great distances, and play a significant role in fluvial, lake and ...
IRTCES2020Field characterization of the negatively buoyant inflow of the Rhône River into Lake Geneva
David Andrew Barry, Ulrich Lemmin, Koen Blanckaert
River inflows have a major influence on lake and reservoir water quality through their input of momentum, heat, oxygen, sediment, nutrients and contaminants. The fate of these components is controlled by the hydrodynamic processes at the interface between ...
2020Field characterization of the negatively buoyant inflow of the Rhône River into Lake Geneva
David Andrew Barry, Ulrich Lemmin, Koen Blanckaert
Turbidity currents emanating from the Rhône River into Lake Geneva were first inferred by François-Alphonse Forel in the nineteenth century. This site remains attractive for several reasons. (1) Permanent measuring stations on the Rhône and Lake Geneva pro ...
2018Influence of outlet discharge on the efficiency of turbidity current venting
Sediment yield into reservoirs was underestimated during the design of dams in the past. As a result, today, reservoir sedimentation is endangering the sustainability of dams. Moreover, the obstruction of rivers hinders their capacity to transport sediment ...
EPFL2017Influence of outlet discharge on the efficiency of turbidity current venting
Reservoirs created by dams are vital water infrastructures worldwide ensuring not only water, food and energy but also protecting against floods. Sedimentation endangers the sustainable use of these reservoirs. Fine sediments transported as suspension duri ...
EPFL-LCH2017Computational hydraulic modelling of fine sediment stirring and evacuation through the power waterways at the Trift reservoir
Anton Schleiss, Pedro Filipe De Almeida Manso, Azin Amini, Célestin Leupi, Sara Venuleo
Taking advantage of the withdrawal of some glaciers, several new dams will eventually be constructed in Switzerland in the coming years as a part of the 2050 energy strategy. The Trift dam, located in Berner Oberlands in Switzerland, is one of these new pr ...
