Experimental study of viscoplastic avalanches striking a water body using PIV techniques.

A recurrent problem in avalanche engineering is related to impulse waves induced by snow avalanches striking a water basin. We took a first step toward the avalanche dynamics when falling into water by using a viscoplastic material that mimics avalanches. ...

Identifying contaminated sediment problems associated with urban stormwater discharges in lakes

Tom Hugo Antoine Benejam

Urban stormwater discharges during wet weather has always been a sensitive issue to deal with. By inducing combined sewer overflows, substantial impacts on receiving water are commonly feared. Aware of this problematic situation, the VSA already created th ...

Hydro-morphological processes through permeable sediment traps at mountain rivers

Sebastian Schwindt

Sediment traps are used for the protection of urban settlements at rivers in mountainous regions. These structures aim at the retention of sediment in the case of hazardous floods, but existing sediment traps tend to retain sediment also when the discharge ...

EPFL2017

Water retention in compacted clays is dominated by multi-modal pore size distribution which evolves during hydro-mechanical paths depending on water content and stress history. A description of the evolutionary fabric has been recently introduced in models ...

Microplastics in Swiss surface waters and going upstream: nature, concentrations, interaction with pollutants

Luiz Felippe De Alencastro, Florian Faure, Olivier Wieser, Colin Demars

Marine microplastic (< 5 mm) water pollution has met growing public and scientific interest in the last years. The situation in freshwater environments remains largely unknown, although they appear to play an important role as part of the origin of marine ...

Impacts by dams: From water quality modelling to management optimization

Alfred Johny Wüest

Dams are prone to causing negative effects on downstream ecosystems by their potential to alter riverine water quality. In the case of Itezhi-Tezhi Reservoir (Zambia), a nutrient-poor wetland located downstream is affected by low oxygen concentrations owin ...

Trace metals and persistent organic pollutants in sediments from river-reservoir systems in Democratic Republic of Congo (DRC): Spatial distribution and potential ecotoxicological effects

Dominique Grandjean, Luiz Felippe De Alencastro

This paper discusses the occurrence and spatial distribution of metals and persistent organic pollutants (POPs: including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), Polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hy ...

The Le Bez torrent in the Canton of Bern, Switzerland, is known for flashy and violent floods due to its watershed topography and vegetation conditions. Such floods can bring a substantial amount of sediment and wood into the small downstream village of Vi ...

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 ...

Innertkirchen compensation basin outlets – Flap gate combined with small stilling basin

Michael Pfister, Fränz Zeimetz

In the context of an update of their hydropower plants, the Hydroelectric Company KWO plans an adaption of their powerhouses Innertkirchen 1 and 2. One aim of the project is, among many others, an optimized restitution regime of the turbined water to the A ...
