Salix response to different flow regimes in controlled experiments: first results

Alexandre Buttler, Paolo Perona, Pascal Turberg, Constant Signarbieux, Lorenzo Gorla

Dams and water management for hydropower production, agriculture and other human activities alter the natural flow regime of rivers. The new river hydrograph components depend on the type of impoundment and the policy of regulation but such a different flo ...

Resilient Rivers - Interdisciplinary Research on Refugia, Connectivity and Stepping Stones

Giovanni De Cesare

The interdisciplinary project Resilient Rivers links research in hydraulic engineering and ecology to explore processes and to evaluate measures related to river restoration. The partners from four different Swiss research institutions together with the ...

NOM degradation during river infiltration: Effects of the climate variables temperature and discharge

Urs von Gunten, Janet Gordon Hering

Most peri-alpine shallow aquifers fed by rivers are oxic and the drinking water derived by riverbank filtration is generally of excellent quality. However, observations during past heat waves suggest that water quality may be affected by climate change due ...

From bedform evolution to channel slope fluctuations in steep-slope streams.

Christophe Ancey, Joris Heyman, François Mettra, Hongbo Ma

In mountain streams, bedload transport rates are prone to strong variability. Indeed an increasing number of laboratory and field studies in steep-slope conditions show fluctuations of bedload transport rate over several temporal and spatial scales. This b ...

WRF-Chem simulations in the Amazon region during wet and dry season transitions: evaluation of methane models and wetland inundation maps

Jed Oliver Kaplan

The Amazon region, being a large source of methane (CH4), contributes significantly to the global annual CH4 budget. For the first time, a forward and inverse modelling framework on regional scale for the purpose of assessing the CH4 budget of the Amazon r ...

Bedload transport powered by daily floods: unsteadiness and stochasticity.

Christophe Ancey, Joris Heyman

The use of geo-sensors in mountain rivers becomes more and more frequent. It provides valuable continuous time series of bedload transport discharge at high temporal resolution that are essential to evaluate, compare and fit theoretical model.This increasi ...

Dynamics and environmental risk assessment of the herbicide glyphosate and its metabolite AMPA in a small vineyard river of the Lake Geneva catchment

Luca Rossi, Pierre-Jean Copin

The use of pesticides may lead to environmental problems, such as surface water pollution, with a risk for aquatic organisms. In the present study, a typical vineyard river of western Switzerland was first monitored to measure discharged loads, identify so ...

Sediment Transport and Flow Conditions in Steep Rivers with Large Immobile Boulders

Tamara Ghilardi

Recent flood events in Switzerland and across Europe pointed out several deficiencies in hazard assessment, planning, and prediction methods for flood risk mitigation. A good understanding of the dynamics of mountain rivers, grounded on a sound physical-ba ...

Pressure drop data and prediction method for enhanced external boiling tube bundles with R-134a and R-236fa

John Richard Thome, Eugene van Rooyen

The pressure drops of external flow over enhanced tube bundles were experimentally obtained at both adiabatic and diabatic conditions using R-134a and R-236fa as test fluids. The tests were carried out at saturation temperatures of 5 and 15 degrees C, mass ...

Debris-Blocking Sensitivity of Piano Key Weirs under Reservoir-Type Approach Flow

Anton Schleiss, Michael Pfister, Blake Tullis

The collection of floating woody debris at flow control structures, such as spillways and weirs, can potentially result in reduced discharge efficiency (higher upstream head for a given weir discharge). Compared to less hydraulically-efficient control stru ...
