Recent developments on management and release techniques of fine sediments in reservoirs
Sedimentation is known as the process of filling up natural lakes and manmade reservoirs by sediment transforming finally into floodplaimns. Its main reason is the sediment yield transported by rivers as suspended or bed load into the reservoirs. Reservoir ...
2019Biomorphological scaling laws from convectively accelerated streams
Paolo Perona, Giulio Calvani, Coralie Schick
Worldwide convectively accelerated streams flowing in downstream-narrowing river sections show that riverbed vegetation growing on alluvial sediment bars gradually disappears, forming a front beyond which vegetation is absent. We revise a recently proposed ...
2019Upstream Erosion and Sediment Passage at Piano Key Weirs
Anton Schleiss, Michael Pfister, Ivan Stojnic
Piano key weirs (PKWs) are a weir type characterized by an effective rating curve. Accordingly, this control structure is primarily applied at dams to increase the spillway capacity. In recent years, PKWs also have been implemented in rivers combined with ...
2019Subaquatic slope instabilities: The aftermath of river correction and artificial dumps in Lake Biel (Switzerland)
Alfred Johny Wüest, Laëtitia Meuriot, Nathalie Dubois
River engineering projects are developing rapidly across the globe, drastically modifying water courses and sediment transfer. Investigation of the impact of engineering works focuses usually on short-term impacts, thus a longer-term perspective is still m ...
2019Morphological 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 ...
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 ...
2018The origin of fine sediment determines the observations of suspended sediment fluxes under unsteady flow conditions
Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez
Field observations in a wide range of environments have shown that sediment availability is a major control on the suspended sediment observations in streams. Here we examine, via laboratory experiments, how the amount of proximal in-channel fine sediment ...
2018Parametric study on the influence of jet-like inflows and outflows on fine sediment settling
Anton Schleiss, Pedro Filipe De Almeida Manso, Samuel Luke Vorlet
This paper focuses on the dynamics of fine sediments in reservoirs exposed to hydropower cascade or pumped-storage operations. The aim is at analysing the influence of parameters such as the flow inlet and flow outlet relative position, the jet hydrodynami ...
Armanini2018Parametric transitions between bare and vegetated states in water-driven patterns
Conditions for vegetation spreading and pattern formation are mathematically framed through an analysis encompassing three fundamental processes: flow stochasticity, vegetation dynamics, and sediment transport. Flow unsteadiness is included through Poisson ...
2018How bar generate sediment transport pulses in gravel-bed channels
Christophe Ancey, Ivan Pascal, Blaise Etienne Marceau Dhont
We ran flume experiments with constant water dis- charge and sediment feed rate at the inlet. Experi- ments were conducted over long times (typically 600 h). The bars migrated downstream intermittently, producing the most important pulses. When the bar pos ...
