Experimental study on bedload transport, fluctuations and coupling with bedforms in steep turbulent streams.
Sediment transport is one of the main morphodynamic processes in mountain streams. Understanding bedload transport is fundamental to prevent and mitigate hydrogeological hazards and for the resources management. The classic bedload discharge predictions ar ...
2018Transport of suspended sediments under the influence of bank macro-roughness
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez
River restoration works often include measures to promote morphological diversity and enhance habitat suitability. One of these measures is the creation of macro-roughness elements, such as lateral cavities and embayments, in the banks of channelized river ...
2018Are Bedload Transport Pulses in Gravel Bed Rivers Created by Bar Migration or SedimentWaves?
Christophe Ancey, Blaise Etienne Marceau Dhont
Bedload transport exhibits considerable spatial and temporal variability, as reflected by large fluctuations of transport rates. Among the various mechanisms proposed for explaining this variability, bedform migration is often cited as the main cause. We t ...
2018Influence of lateral embayments on suspended sediment transport under unsteady flow conditions
Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez, Matthias Thalmann
Local widening in a channelized river is a common practice in restoration projects. The lateral embayments built for this purpose in the river banks are partially filled up by fine sediments. This allows the formation of aquatic habitats with hydraulic and ...
2018Morphological 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 ...
2018Sediment Pulses in a Gravel-Bed Flume with Alternate Bars
The proper understanding of gravel-bed river dynamics is a crucial issue for the effective protection against related natural hazards, design of hydraulic structures, and preservation of their high ecological value in mountain regions. However, despite mor ...
EPFL2017Carbon fate in a large temperate human-impacted river system: Focus on benthic dynamics
Nicolas Thomas Georges Escoffier
Fluvial networks play an important role in regional and global carbon (C) budgets. The Seine River, from the Paris urban area to the entrance of its estuary (220km), is studied here as an example of a large human-impacted river system subject to temperate ...
American Geophysical Union2016Replenishment of sediment downstream of dams: Erosion and transport processes
Large dams in Alpine valleys retain most of the sediments, especially coarse material, which is deposited in the delta of the reservoirs. The common sediment evacuation measures allow to flush only the fine sediments for example by turbidity current ventin ...
EPFL-LCH2016Ecomorphodynamic conditions for the emergence of river anabranching patterns
Paolo Perona, Benoît Crouzy, Paolo d'Odorico
The appearance of the regular vegetated ridge patterns observed in some ephemeral rivers of semi-arid regions (Nanson, Tooth, & Knigthon 2002) has previously been explained by hydraulic arguments (optimization of the bed load transport capacity, see Huang ...
Crc Press-Taylor & Francis Group2014Coupling between flow and sediment deposition in rectangular shallow reservoirs
Anton Schleiss, Erica Camnasio, Michel Pirotton
Flow velocity and sedimentation patterns were investigated experimentally and numerically in shallow rectangular reservoirs with different asymmetric locations of the inlet and outlet channels. Velocity fields were measured in the entire reservoir, both fo ...
