Assimilation of snow depth data from Sentinel-1 to improve the hydrological model of the Borgne catchment (VS)

Since 2013, Crealp (Centre de Recherche sur l’Environnement Alpin) is operating a realtime flood forecasting system for the upper Rhone river basin. The scarcity of meteorological input data at high elevation leads to model uncertainties. In this project, ...

Improving hydropower flexibility by synergizing independently managed utilities

Giovanni De Cesare, Pedro Filipe De Almeida Manso, Sabine Chamoun, Vincent Gaertner, Steve Crettenand

Increasing the flexibility of hydropower allows operators to produce at optimal time ranges, not only dependent on the demand flow but also on the price trends. However, the possibility to improve hydropower flexibility can be hindered when assets are mana ...

Only 42 % of the mean annual production of large hydropower plants in the Swiss Alps is stored in their reservoirs. Once the reservoirs are full at the end of the summer semester, plants are operated as run-on-the-river in order to avoid spilling. A signif ...

Flow measurement for the design optimization of fish pass entries in a run of river hydropower plant

Giovanni De Cesare, Cédric Bron, Pierre Bourqui

The International Commission for the Protection of the Rhine (ICPR) has set the objective of guarantying the upstream migration of the salmons up to Basel, Switzerland, at horizon 2020. One of the last dams to be equipped is the one of Rhinau, in France. T ...

Hydropower Design under Uncertainties

Felix Oberrauch

The design of hydropower is determined by estimates and long-term forecasts. These forecasts and estimates are highly uncertain and make performance evaluation and design choices challenging. Performance evaluation of hydropower projects is affected by a n ...

Transport and mixing in Lac Léman

David Andrew Barry, Ulrich Lemmin, Andrea Cimatoribus

Lake Geneva (Lac Léman) is the largest freshwater body in Western Europe. It is a deep peri-alpine lake whose importance stems from being not only an essential freshwater source in the region, but also a major tourist destination, a fishery and a waterway. ...

The Use of Passive Samplers to Reveal Industrial and Agricultural Pollution Trends in Swiss Rivers

Luiz Felippe De Alencastro, Nicolas Estoppey, Julien Omlin, Adrien Schopfer, Robin Udrisard

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 ...

Active flood management in Alpine catchment areas equipped with storage hydropower schemes

Anton Schleiss, Martin Peter Bieri, Frédéric Jordan

The simulation of runoff in Alpine catchment areas is essential for the optimal operation of high-head storage hydropower plants (HPP) under normal flow conditions, but also in case of flood events. A semi-distributed conceptual numerical approach has been ...

Crc Press-Taylor & Francis Group2013

Hydropeaking is a major issue for storage hydropower plants. Hydropeaking can affect negatively the aquatic environment along river streams. For several hydropower plants studies which analyse measures to reduce the surge effect are currently under prepara ...
