Can runoff event types explain some scatter in nitrate C-Q relationships?

Nitrate contamination of rivers from agricultural sources, is a challenging problem for water quality management. The relationship between solute concentrations and streamflow rates (C-Q) observed at catchment outlets provide useful information on hydrolog ...

Synthesizing the impacts of baseflow contribution on concentration-discharge (C-Q) relationships across Australia using a Bayesian hierarchical model

Camille Roland Marie Minaudo

Understanding concentration-discharge (C - Q) relationships can inform catchment solute and particulate export processes. Previous studies have shown that the extent to which baseflow contributes to streamflow can affect C-Q relationships in some catchment ...

Coupling remote sensing and particle tracking to estimate trajectories in large water bodies

Tamar Kohn, Alfred Johny Wüest, Damien Bouffard, Chaojie Li

Propelled by the rapid development of equipment, technology and computational power, the monitoring and simulation of the hydrodynamics in lakes have steadily advanced. In contrast, water quality simulations are more difficult to implement, due to the diff ...

Hydrological trends for three headwater catchments in the Alptal valley, Switzerland

Jana Freiin von Freyberg, Ilja van Meerveld

Hydrological research in the Alptal valley in central Switzerland started in the late 1960s and has mainly focused on the runoff mechanisms that lead to the very quick runoff response, the relation between forest management and floods, biogeochemistry and ...

Pretreatment options for micropollutant abatement before aquifer recharge in drinking water production: Assessment of UV/H2O2 and dense membranes

Robin Wünsch

Micropollutants (MP) such as residues of pharmaceuticals, industrial chemicals or pesticides can be detected in almost all water resources. Various processes can be used to abate them in drinking water treatment, e.g., ozonation, advanced oxidation process ...

The 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 ...

Business power and the regulation of pollution: oil refineries in Switzerland in the early 1960s

Nicolas Christophe Chachereau

In the late 1950s and in the 1960s, in response to the surge of gasoline and fuel oil consumption, several international oil companies planned the building of refineries in Switzerland, linked to European pipelines. Two were realized, out of four propositi ...

Automated identification of local contamination in an Arctic aerosol time series

Julia Schmale, Andrea Baccarini, Ivo Fabio Beck, Hélène Paule Angot, Lubna Dada

A common challenge of Atmospheric measurements in remote environments is to identify local pollution from nearby sources. During the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) expedition, we measured aerosol and gaseous ...

How natural materials remove heavy metals from water: mechanistic insights from molecular dynamics simulations

Wanda Andreoni, Fabio Pietrucci

Water pollution by heavy metals is of increasing concern due to its devastating effects on the environment and on human health. For the removal of heavy metals from water sources, natural materials, such as spent-coffee-grains or orange/banana/chestnut pee ...

Nearfield development of the negatively buoyant Rhône River inflow into Lake Geneva as an interflow: suspended particulate matter and associated fluxes.

David Andrew Barry, Ulrich Lemmin, Htet Kyi Wynn, Frédéric Charles Soulignac, Benjamin Daniel Graf, Violaine Florette Piton

River inflows have a major influence on lake water quality through their input of sediments, nutrients and contaminants. It is therefore essential to determine their pathways, their mixing with ambient waters and the amount and type of Suspended Particulat ...
