Sediment transfer in the Rhône River Basin, Switzerland: the role of localized severe Alpine storm events on triggering turbidity currents in Lake Geneva

David Andrew Barry, Ulrich Lemmin, Koen Blanckaert, François Mettra

In Lake Geneva, a deep peri-Alpine lake in Switzerland, the sublacustrine Rhône River delta presents a deep canyon, the Rhône Canyon. Previous studies and recent observations show that low-velocity underflows and high-velocity turbidity currents pass frequ ...

Heavy metals and persistent organic pollutants contamination in river, estuary, and marine sediments from Atlantic Coast of Democratic Republic of the Congo

Florian Frédéric Vincent Breider, Dominique Grandjean

The pollution assessment and the evaluation of potential risks in the Atlantic Coastal Region of the Democratic Republic of the Congo are still very limited. Consequently, the present study investigates for the first time the concentrations of heavy metals ...

Quasi-stationary flow structure in turbidity currents

Giovanni De Cesare, Shun Nomura

A turbidity current is a particle-laden current driven by density differences due to suspended sediment particles. Turbidity currents can transport large amounts of sediment down slopes over great distances, and play a significant role in fluvial, lake and ...

Microbial Ecology of Methanotrophy in Streams Along a Gradient of CH4 Availability

Tom Ian Battin, Hannes Markus Peter, Paraskevi Pramateftaki, Alexandre Bagnoud

Despite the recognition of streams and rivers as sources of methane (CH4) to the atmosphere, the role of CH4 oxidation (MOX) in these ecosystems remains poorly understood to date. Here, we measured the kinetics of MOX in stream sediments of 14 sites to res ...

Influence of collars on reduction in scour depth at two piers in a tandem configuration

Anton Schleiss, Giovanni De Cesare, Sargol Memar

Bridge failure, due to local scour at bridge pier foundations, has become a critical issue in river and bridge engineering, which might lead to transportation disruption, loss of lives and economic problems. A practical solution to prevent bridge collapses ...

Optimised biomolecular extraction for metagenomic analysis of microbial biofilms from high-mountain streams

Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Jade Brandani, Stylianos Fodelianakis, Paraskevi Pramateftaki

Glacier-fed streams (GFS) are harsh ecosystems dominated by microbial life organized in benthic biofilms, yet the biodiversity and ecosystem functions provided by these communities remain under-appreciated. To better understand the microbial processes and ...

Effect thresholds of metals in stream sediments based on in situ oligochaete communities

Benoît Jean Dominique Ferrari, Régis Lionel Vivien

Aquatic oligochaetes, comprising a large number of species showing various degrees of resistance to chemical pollution, are recognized as valuable bioindicators of sediments’ quality. In the Geneva area (Switzerland), oligochaete tools were previously test ...

Analyzing and modeling sub-diffusive transport of bedload along a heterogeneous gravel bed using stochastic and statistical methods

Zhenzhu Meng, Zhipeng Li, Yong Zhang

Bedload transport is one of the main mechanisms for sediment transport in rivers. Bedload transport may exhibit anomalous dispersion behavior during the formation of clusters on the surface of a heterogeneous river bed, which cannot be quantified by the cl ...
