Hydromorphological 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 ...
EPFL2023Enhancing 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)2023Continuous monitoring of morphological changes from sediment augmentation by field measurements and flume experiments
Giovanni De Cesare, Christian Mörtl
In this study, we present results from continuous field monitoring and a flume ex-periment of a sediment augmentation measure in a residual flow reach of the Swiss midlands. A straight morphological channel with fixed bed material was constructed to repres ...
2023Insights Into the Dynamics of Vegetated Alternate Bars by Means of Flume Experiments
Alternate bars are bedforms recognizable in straight or weakly curved channels as a result of riverbed instability. The length and height of alternate bars scale with the river width and the water depth, respectively. During low water stages, alternate bar ...
2023Erosion 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 ...
2019Hydraulic-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 ...
EPFL2019The impact of hydrograph variability and frequency on sediment transport dynamics in a gravel-bed flume
Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez
A laboratory study was undertaken to investigate how changes in flow regime and hydrograph shape (number of cycled hydrographs and duration of each hydrograph) together impact bedload transport and resulting bed morphology. Three hydrologic conditions (exp ...
WILEY2019Morphological resilience to flow fluctuations of fine sediment deposits in bank lateral cavities
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez, Matthias Thalmann
Lateral cavities are built in the banks of rivers for several purposes: to create harbors, to capture sed- iment, to keep a central navigable channel (i.e., Casiers de Girardon in the Rhone river) or to promote the formation of aquatic habitats if a limite ...
2018Design optimization of permeable sediment traps for fluvial bed load transport
Anton Schleiss, Sebastian Schwindt, Mona Jafarnejad Chaghooshi, Anita Hélène Roth
Sediment traps are crucial elements for flood protection in mountain rivers with high sediment transport capacity. Existing structures often interrupt the channel connectivity. Ideally, a sediment trap should be permeable for bed load during non-hazardous ...
2018Preventing fine sediment settling with jet-like inflows and intake-like outflows in reservoirs
Reservoir sedimentation is one of the main issue in the operational management of dams. The resulting filling up of reservoirs has negative impacts on hydropower production, irrigation, flood protection and drinking water supply. New economical and sustain ...
