The biofilm ecology of proglacial floodplain streams

Glacial forelands figure among the most dynamic landscapes on Earth, and their formation is currently accelerating given glacier shrinkage. Draining these forelands are streams hosting unique microbial communities, which have the capacity to impact both th ...

Generation and application of river network analogues for use in ecology and evolution

Andrea Rinaldo, Enrico Bertuzzo, Luca Carraro, Reinhard Furrer, Florian Altermatt

Several key processes in freshwater ecology are governed by the connectivity inherent to dendritic river networks. These have extensively been analyzed from a geomorphological and hydrological viewpoint, yet structures classically used in ecological modeli ...

Catchment drainage network scaling laws found experimentally in overland flow morphologies

David Andrew Barry, Andrea Rinaldo, Paolo Perona, Mohsen Cheraghi

The scaling relation between the drainage area and stream length (Hack’s law), along with exceedance probabilities of drainage area, discharge and upstream flow network length are well known for channelized fluvial regions. We report here on a laboratory e ...

Transport of suspended sediments under the influence of bank macro-roughness

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez

River restoration works often include measures to promote morphological diversity and enhance habitat suitability. One of these measures is the creation of macro-roughness elements, such as lateral cavities and embayments, in the banks of channelized river ...

Using SAS functions and high-resolution isotope data to unravel travel time distributions in headwater catchments

Andrea Rinaldo, Paolo Benettin, Gianluca Botter

We use high-resolution tracer data from an experimental site to test theoretical approaches that integrate catchment-scale flow and transport processes in a unified framework centered on selective age sampling by streamflow and evapotranspiration fluxes. T ...

Linear scaling of precipitation-driven soil erosion in laboratory flumes

David Andrew Barry, Seifeddine Jomaa

The proportionality between raindrop-driven soil erosion delivery and area of soil exposed to raindrops under a uniform precipitation rate was investigated in terms of individual size classes using laboratory flume experiments. In particular, we examined t ...

Experimental characterization of vegetation uprooting by flow

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier

We investigate vegetation uprooting by flow for Avena sativa seedlings with stem-to-sediment size ratio close to unity and vanishing obstacle-induced scouring. By inducing parallel riverbed erosion within an experimental flume, we measure the time-to-uproo ...

Observation and modeling of catchment-scale solute transport in the hydrologic response: A tracer study

Andrea Rinaldo, Gianluca Botter

The coherent description of water flow and solute transport within heterogeneous hydrologic media (e.g., hillslopes or entire catchments) in response to external rainfall forcings represents a challenge in hydrological modeling. In this paper the mechanism ...

Benthic macroinvertebrates and logging activities

Pascale Derleth

At the beginning of the 21 century, the conservation of biodiversity and the sustainable use of natural resources remains a matter of concern. Within this framework, the aim of this research was to study the effects of logging activities on ecological wate ...

Typologie des eaux souterraines du Flysch de la nappe tectonique du Niesen (Préalpes suisses)

The typology of the underground waters of the flyschs of the Niesen and Gurnigel tectonic nappes form part of the AQUITYP project which has been worked on by the geology laboratory of the Swiss Federal Institute of Technology in Lausanne since 1981. Its pr ...
