The hydro-morpho-sedimentary processes in confluence hydrodynamic zones (CHZ) subject to a local widening of the tributary were investigated in a series of laboratory experiments that were representative of the 20 major confluences of the Upper Rhone River ...
This study shows the efficiency of passive sampling to reveal industrial and agricultural pollution trends. Two practical applications for nonpolar and polar contaminants are presented. Low-density polyethylene (LDPE) samplers were deployed for one year in ...
Beaucoup d’études ont à ce jour été publiée sur la pollution par les (micro-)plastiques des milieux marins. Par contre, la situation dans les environnements d’eaux douces et les transports des (micro-)plastiques vers ces océans font l’objet d’une récente a ...
With its smaller size, well-known boundary conditions, and the availability of detailed bathymetric data, Lake Geneva's subaquatic canyon in the Rhone Delta is an excellent analogue to understand sedimentary processes in deep-water submarine channels. A mu ...
The Gebidem Dam located on the Massa River intercepts annually around 400’000 m3 of solid material. These sediments must be evacuated by annual flushing of the reservoir over 4 to 7 days. A trend for silting in the flushing channel was observed during the ...
A complex hydrologic-hydraulic model has been developed for the Upper Rhone River basin in Switzerland. It is currently operational in the Canton of Valais for real-time flood forecasting and management, providing automatic warnings to the crisis cell of t ...
In summer 2011, the two Russian MIR submersibles were brought to Switzerland to perform deep water dives in Lake Geneva. Research teams from several environmental science institutes, both national and international, participated in this interdisciplinary e ...
Pyrethroids and organophosphates are among the most toxic insecticides for aquatic organisms, leading to annual-average environmental quality standards (AA-EQS) in the picogram per liter range in surface waters. For monitoring purposes, it is therefore cru ...
Le site choisi est celui du village du Bouveret, situé dans la plaine du delta du Rhône chablaisien suisse. Ce lieu est caractérisé principalement par son isolement: d'une part par sa situation au sein d'un territoire lui-même isolé, le Chablais suisse, d' ...
Les sources diffuses de contamination dans le Lac Léman font régulièrement l’objet de suivi par l’entremise de la CIPEL et de travaux de recherche, notamment le projet LEMAN21 (www.leman21.ch). Plusieurs questions restent néanmoins ouvertes, en ce qui conc ...
