Homogeneous Environmental Selection Structures the Bacterial Communities of Benthic Biofilms in Proglacial Floodplain Streams

Tom Ian Battin, Hannes Markus Peter, Tyler Joe Kohler, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Stylianos Fodelianakis, Massimo Bourquin, Leïla Ezzat, Jade Brandani

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 ...

Controlling factors of phytoplankton distribution in the river–lake transition zone of a large lake

David Andrew Barry, Frédéric Charles Soulignac

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 ...

Unexpected large evasion fluxes of carbon dioxide from turbulent streams draining the world’s mountains

Tom Ian Battin, Enrico Bertuzzo, Amber Joy Ulseth, Asa Lovisa Viktoria Horgby, Pier Luigi Segatto

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 ...

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

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

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 ...

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 ...

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 ...

Local tributary widening for river rehabilitation

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro

The hydro-morpho-sedimentary processes in confluence hydrodynamic zones (CHZ) subject to a local widening of the tributary were investigated in a series of laboratory experiments that were representative of the 20 major confluences of the Upper Rhone River ...

Morphodynamics in river confluences

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

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 ...

Morphodynamic differences induced by different confluence angles in widen confluences

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

River widening is commonly used as a solution for the rehabilitation of rivers with the main purposes of allowing the river to adjust to its natural dynamics and to improve riparian and instream habitat for flora and fauna, by increasing the heterogeneity ...

Three dimensional flow field at confluent fixed-bed open channels

Sebastián Guillén Ludeña

River confluences are known for their marked 3D patterns and, due to the complexity of local flow features and bed morphology, they require particular consideration. Although there are studies on the flow structure in junctions of two streams, amore detail ...

A microstructural approach to bed load transport: mean behaviour and fluctuations of particle transport rates

Christophe Ancey, Joris Heyman

This paper concerns a model of bed load transport, which describes the advection and dispersion of coarse particles carried by a turbulent water stream. The challenge is to develop a microstructural approach that, on the one hand, yields a parsimonious des ...

Early Anthropogenic Transformation of the Danube-Black Sea System

Jed Oliver Kaplan

Over the last century humans have altered the export of fluvial materials leading to significant changes in morphology, chemistry, and biology of the coastal ocean. Here we present sedimentary, paleoenvironmental and paleogenetic evidence to show that the ...

Influence of Tributary Widening on Confluence Morphodynamics

Marcelo Leite Ribeiro

In alpine regions of Europe, river training works were typically the reason for the transformation of wide and braided rivers into linear river systems with a lack of structural diversity, i.e. gravel banks, islands, woody debris, riffles or pools. These i ...

Flood Management in a Complex River Basin with a Real-Time Decision Support System Based on Hydrological Forecasts

Javier García Hernández

During the last decades, the Upper Rhone River basin has been hit by several flood events causing significant damages in excess of 500 million Swiss Francs. From this situation, the 3rd Rhône river training project was planned in order to improve the flood ...

Influence of the widening of a tributary on confluence morphology: preliminary results

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro

The aim of this work is to obtain a better understanding of the morphological development in alpine river confluences, where special attention is given to the widening of the tributary channel and its influence on bed morphology evolution. Hydraulic tests ...
