Spatiotemporal Dynamics of Flow and Hydrochemistry in Drainage Networks
Despite their high ecological value, non-perennial streams have received less attention than their perennial counterparts. This doctoral thesis addresses this disparity by advancing knowledge on the dynamics of the drainage density and hydrologic processes ...
EPFL2024Morphometry of Tidal Meander Cutoffs Indicates Similarity to Fluvial Morphodynamics
Sinuous channels wandering through coastal wetlands have been thought to lack lateral-migration features like meander cutoffs and oxbows, spurring the broad interpretation that tidal and fluvial meanders differ morphodynamically. Motivated by recent work s ...
Washington2024Technical note: Two-component electrical-conductivity-based hydrograph separation employing an exponential mixing model (EXPECT) provides reliable high-temporal-resolution young water fraction estimates in three small Swiss catchments
Jana Freiin von Freyberg, Davide Canone
The young water fraction represents the portion of water molecules in a stream that have entered the catchment relatively recently, typically within 2-3 months. It can be reliably estimated in spatially heterogeneous and nonstationary catchments from the a ...
Copernicus Gesellschaft Mbh2024Bifurcations in mountain rivers: insights on their hydraulics from field measurements.
Christophe Ancey, Ivan Pascal, Bob de Graffenried, Raphaël Miazza
Although the importance of studying channel bifurcations is widely recognised, their hydraulic behaviour in shallow, rough mountain rivers has so far received little attention from researchers. Understanding the specific hydraulics of such units is essenti ...
2023Homogeneous Environmental Selection Structures the Bacterial Communities of Benthic Biofilms in Proglacial Floodplain Streams
Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Tyler Joe Kohler, Jade Brandani, Stylianos Fodelianakis
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 ...
AMER SOC MICROBIOLOGY2023Short-term dynamics of drainage density based on a combination of channel flow state surveys and water level measurements
Andrea Rinaldo, Jana Freiin von Freyberg, Izabela Bujak-Ozga
Headwater streams often experience intermittent flow. Consequently, the flowing drainage network expands and contracts and the flowing drainage density (DD) varies over time. Monitoring the DD dynamics is essential to understand the processes controlling i ...
Hoboken2023Glacier retreat and increasing vegetation cover alter the sources and sinks of organic and inorganic carbon in alpine streams
Nicola Deluigi, Andrew Lean Robison
High-mountain ecosystems are experiencing acute effects of climate change, most visibly through glacier recession and the greening of the terrestrial environment. The streams draining these landscapes are affected by these shifts, integrating hydrologic, g ...
2023CHARACTERIZING THE RESILIENCE AND ADAPTATION OF BIOFILM COMMUNITIES TO CLIMATE CHANGE IN GLACIER-FED STREAMS
Tom Ian Battin, Hannes Markus Peter, Grégoire Marie Octave Edouard Michoud, Nicola Deluigi, David Touchette, Martina Gonzalez Mateu, Florian Baier
Biofilms conform the dominant microbial lifestyle in alpine streams where they are major contributors to carbon and nutrient cycling. However, relatively little is known about their adaptive capacity to climate change as water temperature rises and hydrolo ...
2023The dark side of the moon: A glimpse into the future of the microbiome structure and function of glacier-fed streams
Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Grégoire Marie Octave Edouard Michoud, Leïla Ezzat, Massimo Bourquin, Tyler Joe Kohler
Glaciers are receding at an unprecedented rate with expected losses of up to half their masses by 2100. Such changes will have a profound effect on the physicochemical characteristics of glacier-fed stream (GFS) water, such as the composition of organic ma ...
2023The present and future of alpine streams: A microbial functionality perspective
Tom Ian Battin, Hannes Markus Peter, Grégoire Marie Octave Edouard Michoud, Tyler Joe Kohler, Jade Brandani
Alpine streams are among the most impacted freshwater ecosystems due to climate change. Depending on water origin, streams within alpine catchments are divided into glacier-fed, groundwater, and snowmelt streams. With the shrinking of glaciers due to clima ...
