Spatiotemporal Dynamics of Flow and Hydrochemistry in Drainage Networks

Izabela Bujak-Ozga

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 ...

A Survey of Industrial N-nitrosamine Discharges in Switzerland

Urs von Gunten, Florian Frédéric Vincent Breider, Caroline Gachet Aquillon

N-nitrosamines are formed during different industrial processes and are of significant concern due to their carcinogenic and mutagenic properties. This study reports concentrations of N-nitrosamines in eight different industrial wastewater treatment plants ...

Hydrological trends and the evolution of catchment research in the Alptal valley, central Switzerland

Jana Freiin von Freyberg, Ilja van Meerveld

When the observation of small headwater catchments in the pre-Alpine Alptal valley (central Switzerland) started in the late 1960s, the researchers were mainly interested in questions related to floods and forest management. Investigations of geomorphologi ...

Accurate drainage network extraction and monitoring in a high-mountain catchment

Andrea Rinaldo, Marc Parlange, Raphaël Mutzner

We study the accuracy of channel network extraction methods obtained in two subcatchments of an alpine watershed in Switzerland and compare the results to the ones obtained with the real network, carefully monitored with a high precision DGPS during Summer ...

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 ...

Snow cover runoff and stream discharge modelling during snow melt in Alpine terrain

Michael Lehning, Nander Wever, Mathias Thierry Pierre Bavay, Charles Fierz

The understanding of the role of snow cover runoff in complex terrain for the hydrological cycle is still limited. Water flow in snow is a complex process, because the strong layering of the snow cover causes strong vertical variation in hydraulic properti ...

LOCALIZATION OF POINT SOURCES OF POLYCHLORINATED BIPHENYLS (PCBs) POLLUTION IN RIVERS USING PASSIVE SAMPLERS

Luiz Felippe De Alencastro, Jonas Milani, Nicolas Estoppey, Julien Omlin, Jan Philipp Robra, Louise Gilbert, Juliana León, Nancy El Ghorayeb

Polychlorinated biphenyls (PCBs) are universal environmental contaminants that have attracted great concern because of their worldwide distribution, persistence in the environment and possible harmful effects. Recycling old objects or materials containing ...

Localization of point sources of PCBs pollution in rivers using LDPE passive samplers, a Swiss case study

Luiz Felippe De Alencastro, Nicolas Estoppey, Julien Omlin, Nancy El Ghorayeb

Due to its situation of “Europe’s water reservoir”, Switzerland has a particular responsibility towards downstream countries. It must ensure an optimal quality of its surface waters, following thus the example of the EU members which have to reach by 2015 ...

Substance flow analysis as a tool for urban water management

Luca Rossi, Nathalie Chèvre Rossi

Human activity results in the production of a wide range of pollutants that can enter the water cycle through stormwater or wastewater. Among others, heavy metals are still detected in high concentrations around urban areas and their impact on aquatic orga ...

Optimized and adapted hydropower management considering glacier shrinkage scenarios in the Swiss Alps

Anton Schleiss, Frédéric Jordan, Stéphane Christian Olivier Terrier

Global warming is an alarming reality and likely leads to an increase of multiple pressures on socio-economic systems. However, in high-mountain regions it might also become an opportunity to adapt existing hydropower schemes and future projects to this ne ...
