Bedform migration in steep channels: from local avalanches to large scale changes.

Christophe Ancey, Joris Heyman, François Mettra

Many studies have emphasized the strength of bedload transport fluctuations in steep streams, especially at low and intermediate transport conditions (relative to the threshold of incipient motion). The origins of these fluctuations, which appear on a wide ...

Multiple criteria design analysis of a compensation basin to mitigate hydro-pealink

Stéphane Christian Olivier Terrier, Felix Oberrauch

Hydropeaking is a major issue for storage hydropower plants. Hydropeaking can affect negatively the aquatic environment along river streams. For several hydropower plants studies which analyse measures to reduce the surge effect are currently under prepara ...

Catchment-scale herbicides transport: Theory and application

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter

This paper proposes and tests a model which couples the description of hydrologic flow and transport of herbicides at catchment scales. The model accounts for streamflow components' age to characterize short and long term fluctuations of herbicide flux con ...

Comparison of hydrologic response between a conceptual and a travel time distribution model for a snow-covered alpine catchment using Alpine3D

Andrea Rinaldo, Michael Lehning, Marc Parlange, Bettina Schaefli, Francesco Comola, Mathias Thierry Pierre Bavay, Raphaël Mutzner

Fully distributed models of alpine catchment surface processes typically use the geomorphological information provided by digital maps for describing the dynamics of rain, snow, soil and vegetation with much detail. Physically based hydrological models wou ...

Improving stream flow discharge modelling during snow melt

Michael Lehning, Nander Wever, Charles Fierz

The importance of the snow cover for the hydrological cycle is well known but the understanding is still limited. For example, the effect of rain-on-snow on melt water runoff and the coupling between spring snow melt and stream flow discharge are difficult ...

Stream Water Temperature Modeling For An Alpine Catchment

Vasco Andrea Neuhaus

Stream water temperature is an important key factor for water quality of rivers. Different approaches for stream temperature modeling have been developed over the past few decades and can basically be grouped into heat balance and stochastic models. Energy ...

The Hydro-Morphological Index of Diversity

Walter Gostner

Contemporary river engineering must guarantee effective long-term flood protection while also improving stream ecology. Nowadays, river engineering projects must aim at optimizing hydromorphological heterogeneity, as this is an acknowledged basic condition ...

Hydromorphological implications of local tributary widening for river rehabilitation

Anton Schleiss, Koen Blanckaert, Marcelo Leite Ribeiro, André Roy

The hydromorphological implications of the local widening of a tributary where it enters a confluence were investigated in a laboratory setting that is representative of the 20 major confluences on the channelized Upper Rhone River. Although local tributar ...

Characterization of bedload transport in steep-slope streams.

Christophe Ancey, Joris Heyman, François Mettra

Large fluctuations in the sediment transport rate are observed in rivers, particularly in mountain streams at intermediate flow rates. These fluctuations seem to be, to some degree, correlated to the formation and migration of bedforms. Today the central q ...
