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/Balkema2023Reduction 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/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 ...
2023Enhancing 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)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 ...
IRTCES2022Erosion, transport and deposition of a sediment replenishment under flood conditions
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Christopher Robinson
River reaches downstream of dams with constant residual discharge often lack sediment supply and periodic high flows due to dam sediment retention and flow regulation, respectively. To test a novel multi-deposit methodology for defining environmental flows ...
2020Design of sediment detention basins: Scaled model experiments and application
Anton Schleiss, Sebastian Schwindt, Mona Jafarnejad Chaghooshi, Anita Hélène Roth
Sediment detention basins are implemented on mountain rivers to trap solid material that may aggravate the flooding of downstream settlements. However, retention structures built in the past may unnecessarily retain sediment during non-hazardous flood even ...
2020Hydraulic-morphological habitat assessment in rivers considering residual flow, sediment replenishment and artificial flood events
Dams store water and trap sediment in their reservoirs. Downstream river segments, hence, are affected by a limited sediment dynamics. This becomes obvious by river bed incision, limited geomorphological variability and depletion of hydraulic habitats for ...
EPFL2019Sediment replenishment combined with an artificial flood improves river habitats downstream of a dam
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Severin Stähly, Christopher Robinson
River reaches downstream dams where a constant residual flow discharge is imposed, often lack sediment supply and periodic inundation due to the absence of natural flood events. In this study, a two-year return flood was released from an upstream reservoir ...
2019Erosion processes of a novel configuration of sediment replenishment during an artificial flood
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Severin Stähly, Christopher Robinson
Floodplains downstream of dams with constant residual flow discharge often lack sediment supply and periodic inundation due to the absence of flood events. At the Sarine floodplain in Fribourg, western Switzerland, an artificial flood was released from Ros ...
