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 ...

Antidunes on steep slopes: variability of wave geometry and migration celerity

Christophe Ancey, Ivan Pascal

As a result of interactions between streamflow andsediment, riverbeds are seldom smooth, but depending onhydraulic and sediment transport conditions, they exhibitbedforms, which grow and migrate over time (upstreamor downstream). Morphology migration may e ...

Sediment traps with guiding channel and hybrid check dams improve controlled sediment retention

Mário Jorge Rodrigues Pereira Da Franca, Sebastian Schwindt, Stefano Tugulu, Alessandro Reffo

Sediment traps with partially open check dams are crucial elements for flood protection in alpine regions. The trapping of sediment is necessary when intense sediment transport occurs during floods that may endanger urban areas at downstream river reaches. ...

Nitrification increases nitrogen export from a tropical river network

Janine Rüegg

Scaling aquatic ecosystem processes like nutrient removal is critical for assessing the importance of streams and rivers to watershed nutrient export. We used pulse NH4+ enrichment experiments and measured net NH4+ uptake in 7 streams throughout a mountain ...

Hydromorphodynamic effects of the width ratio and local tributary widening on discordant confluences

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña, António Heleno Cardoso

River training works performed in the last couple of centuries constrained the natural dynamics of channel networks in locations that include the confluences between tributaries and main channels. As a result, the dynamics of these confluences are currentl ...
