Design improvements for combined sediment-wood detention at mountain streams

Giovanni De Cesare, Azin Amini, Romain Nathan Hippolyte Merlin Van Mol

Bedload transport and driftwood in steep mountain streams can cause serious damage to local communities in the vicinity of watercourses. To prevent such damage, check dams are typically built to hold back sediment and driftwood. However, by completely inte ...

Hydraulic analysis of Snowy 2.0 pumped storage facilities using hybrid models: validating performance and anti-vortex measures

Giovanni De Cesare, Azin Amini, Eugenio Mazzocchi

Abstract: Within the framework of the Snowy 2.0 large-scale pumped-storage facility project in Australia, hybrid experimental and numerical modeling of Tantangara (upper reservoir) and Talbingo (lower reservoir) intake/outlet structure were carried out. Th ...

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 ...

Characterization 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 ...

Contribution of the Hydraulic Laboratories of the Swiss Federal Institutes of Technology to Dam Safety

Giovanni De Cesare, Azin Amini, Samuel Luke Vorlet

Bien que la construction de barrages en général et l’hydraulique des barrages en particulier soient des domaines techniques très développés, le potentiel de risque associé aux barrages justifie dans la plupart des cas la vérification et l’optimisation de l ...

Physical Modeling of Sediment Trap for Le Bez River, Switzerland

Giovanni De Cesare, Azin Amini, Romain Nathan Hippolyte Merlin Van Mol, Najla Schaller

The Le Bez torrent in the Canton of Bern, Switzerland, is known for flashy and violent floods due to its watershed topography and vegetation conditions. Such floods can bring a substantial amount of sediment and wood into the small downstream village of Vi ...

Exploring the efficacy of reservoir fine sediment management measures through numerical simulations

Giovanni De Cesare, Azin Amini, Samuel Luke Vorlet, Montana Marshall

Reservoir sedimentation is one of the main challenges in the sustainable operation of large reservoirs because it causes volume loss, affecting hydropower production capacity, dam safety, and flood management. To ensure the sustainability of deep reservoir ...
