Analysis of sediment transport from recorded signals of sediments in a gravel-bed river: role of sediment availability
Geophones were used as a proxy for determining the behavior of sediment transport in boulder mountain river. Field observations aggregated by a statistical analysis (PCA) allowed to identifying periods in which the behaviour between the water discharge $(Q ...
Springer international Publishing2014Ecomorphodynamic 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 Group2014Bedload transport powered by daily floods: unsteadiness and stochasticity.
Christophe Ancey, Joris Heyman
The use of geo-sensors in mountain rivers becomes more and more frequent. It provides valuable continuous time series of bedload transport discharge at high temporal resolution that are essential to evaluate, compare and fit theoretical model.This increasi ...
2013Sediment Suspension Dynamics in Turbulent Unsteady, Depth-Varying Open-Channel Flow over a Gravel Bed
Fereshteh Bagherimiyab Hunkeler
Even though flow in natural rivers and channels is generally unsteady, only a few studies on turbulent structures in unsteady open-channel flows have been carried out. In hydraulic engineering problems, unsteady flow is often approximated with concepts of ...
EPFL2012Flow and sediment dynamics in channel confluences
Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro, André Roy
Confluences with relatively low discharge and momentum flux ratios where a small steep tributary with a high supply of poorly sorted sediment joins a large, low-gradient main channel commonly occur in nature, but they have not yet been investigated. Measur ...
