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 ...
2023The clogging of riverbeds: A review of the physical processes
Giovanni De Cesare, Romain Maxime Dubuis
Fine sediment represents an important part of the solid flux of rivers. Due to the size of these particles, they are often transported as suspended load. They gradually fill the pores of the substrate forming the hyporheic zone or cover the substrate by se ...
