Streams draining proglacial floodplains harbor benthic biofilms comprised of diverse microbial communities. These high-mountain ecosystems are rapidly changing with climate warming, and it is therefore critical to better understand the mechanisms underlyin ...

River–lake transition zones have been identified as major drivers of phytoplankton growth. With climate change reducing the frequency of complete lake overturns, it is expected that the Rhône River, the main tributary to Lake Geneva (France/Switzerland), w ...

The role of glaciers as sources of stream nutrients in a high mountain catchment

In the high mountain environments, streams often appear nutrient-limited. In glaciated catchments however, glacier meltwater acts as sources of nitrogen (N) and phosphorus (P) to downstream ecosystems, but research investigating t ...

Inland waters, including streams and rivers, are active components of the global carbon cycle.Despite the large areal extent of the world’s mountains, the role of mountain streams forglobal carbonfluxes remains elusive. Using recent insights from gas excha ...

Inland waters are key components of the global carbon cycle, emitting a substantial amount of carbon dioxide (CO2) to the atmosphere. Climate change and global warming affect mountain catchments significantly, leading to glacier retreat and changing precip ...

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 ...

Zambezi River Basin

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos

With a basin covering 1.4 million km2, the Zambezi is the fifth largest drainage basin in Africa. Bounded by the 9°S and 21°S parallels, it is home to approximately 30 million people and is officially shared by eight riparian countries. The river stretches ...

Hydrodynamics of mountain-river confluences and its relationship to sediment transport

Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña

Mountain confluences are characterized by narrow and steep tributaries that provide important sediment load to the confluence, whereas themain channel supplies the dominant flow discharge. This results in a marked bed discordance between the tributary and ...

The role of the hyporheic flow on sediment transport processes : an experimental approach using particle image velocimetry.

Christophe Ancey, Gauthier Paul Daniel Marie Rousseau, Daniel Vito Papa, Angeliki Sklivaniti

The study of river dynamics usually considers a turbulent stream on an impervious bed. However, it is known that part of the total discharge takes place through the erodible bed, especially for mountain rivers. This hyporheic flow (or subsurface flow) is l ...

Numerical simulation of 3D flow in right-angled confluences with bed elevation discordance in both converging channels

Ivan Stojnic

The paper studies a combined effect of bed steps (BS) in both converging channels on the 3D flow in a confluence with alpha = 90 degrees. Nine combinations of bed elevation discordance ratio values in the two channels are analysed. It is shown that: 1) a p ...
