The role of mass-transport deposits and turbidites in shaping modern lacustrine deepwater channels

Subaquatic canyons are an important pathway for sediment transport into oceanic and lacustrine basins. Understanding the mechanisms governing their geomorphological evolution is a key to predict the sediment distribution patterns through these sediment con ...

Replenishment of sediment downstream of dams: Erosion and transport processes

Elena Battisacco

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 ...

CO2 evasion from a steep, high gradient stream network: importance of seasonal and diurnal variation in aquatic pCO2 and gas transfer

Tom Ian Battin, Amber Joy Ulseth

Surface waters contribute substantially to carbon dioxide (CO2) emissions to the atmosphere. However, global estimates remain uncertain due to methodological difficulties, such as in precisely estimating gas transfer in steep upland streams. Here, we addre ...

Influence of consecutive sediment replenishment on channel bed morphology

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Elena Battisacco, Lena Bösch

Dams interrupt the longitudinal connectivity of a river as they store water and trap sediment. When transport capacity downstream of dams exceeds sediment supply, water becomes hungry and channel incision, bed armouring and reduction of morphological diver ...

Metabolism of mineral-sorbed organic matter depends upon microbial lifestyle in fluvial ecosystems

Tom Ian Battin

In fluvial ecosystems mineral erosion, carbon (C) and nitrogen (N) fluxes are linked via organo-mineral complexation, where dissolved organic molecules bind to mineral surfaces. Biofilms and suspended aggregates represent major aquatic microbial lifestyles ...

Evolution of the hydromorphodynamics of mountain river confluences for varying discharge ratios and junction angles

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

Mountain river confluences are characterized by narrow and steep tributaries that supply abundant sediment load to a main channel that, in turn, provides the dominant flow discharge. In addition, bed sediments consist of poorly sorted mixtures that promote ...

Detection and sequence/structure mapping of biophysical constraints to protein variation in saturated mutational libraries and protein sequence alignments with a dedicated server

Matteo Dal Peraro, Luciano Andres Abriata, Christophe Bovigny

Background: Protein variability can now be studied by measuring high-resolution tolerance-to-substitution maps and fitness landscapes in saturated mutational libraries. But these rich and expensive datasets are typically interpreted coarsely, restricting d ...

Effects of endogeic earthworms on the soil organic matter dynamics and the soil structure in urban and alluvial soil materials

Pascal Turberg, Jean-Michel Gobat, Renée-Claire Le Bayon

Earthworms are considered as key actors of soil processes at different spatial and temporal scales and provide essential ecosystem services linked to climate regulation or primary production. However, little is known about their basic functional roles (e.g ...

Morphodynamics in river confluences

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

Within the fluvial network, confluences are considered particular areas in what concerns ecological connectivity, flood safety and water quality. These characteristics were degraded in many cases, by previous channelization works, which resulted in rivers ...

Hydro-morphodynamic differences induced by different angles in an experimental discordant confluence

Sebastián Guillén Ludeña

Confluences, within the fluvial network, are considered particular areas with great ecological value, where flow dynamics and bed morphology are complex and highly three-dimensional. Several parameters influence the morphodynamics and hydrodynamics of rive ...
