Enhancing Flood Resilience: Sediment Management in Le Bez Torrent
Giovanni De Cesare, Azin Amini, Romain Nathan Hippolyte Merlin Van Mol
In the canton of Bern, Switzerland, the “Le Bez” torrent is known for its flash floods, causing sediment and wood debris buildup in Villeret village settled on the alluvial fan. To mitigate this issue, a sediment/wood trap system is being implemented upstr ...
Swiss Academy of Sciences (SCNAT)2023Reduction of riverbed clogging related to sediment flushing
Giovanni De Cesare, Romain Maxime Dubuis
The ecological effects of dams on sediment and river flow have been subject to an increasing attention, leading to the implementation of mitigation measures such as environmental flow release and sediment replenishment. However, fine sediment dynamics have ...
CRC Press/Balkema2023Experimental 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 ...
2023Impact of substrate clogging on vertical connectivity
Giovanni De Cesare, Romain Maxime Dubuis, Robin Schroff
Connectivity between the hyporheic zone and the flow is essential for the development of benthos and the reproductive success of spawning fish. The infiltration of fine sediment leads to clogging of the riverbed, reducing porosity and vertical water exchan ...
2023Influence of channel geomorphic units on bedload transport and river morphology during low‐magnitude bed‐forming floods coupled with sediment augmentation
Giovanni De Cesare, Severin Stähly, Christian Mörtl, Robin Schroff
In this study, we map different types of channel geomorphic units in a sediment-starved, residual-flow reach before and after an artificial flood. Bedload particles of a previous sediment augmentation measure are tracked with passive integrated transponder ...
2023Clogging of riverbed substrates by fine sediment
Riverbeds represent the habitat of numerous aquatic species. Exchanges between the groundwater, the hyporheic zone and the surface flow are also essential for river ecosystems. Fine sediment transported by rivers deposits inside or on top of the bed and mo ...
EPFL2023Hydromorphological assessment of sediment augmentation measures in gravel-bed rivers
In the riverine environment, the riverscape, sediment and flow regime are essential drivers for natural habitat dynamics. Today, most water courses in Europe are regulated, and their natural dynamics are impaired. Flood releases coupled with the artificial ...
EPFL2023p 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 ...
