In the context of energy transition, hydropower is poised to have a major importance in the coming decades. It therefore requires the development of reliable, innovative solutions for maintenance and rehabilitation. Geomembrane systems are a promising tech ...

In order to increase the installed capacity, the refurbishment of Gondo high-head power plant required a modification of the existing surge tank by installing a throttle at its entrance. In a previous study, the geometry of this throttle was optimized by p ...

Reservoir sedimentation is, at present, one of the main concerns in the operational management of dams in the Alps. For larger seasonal storage reservoirs, the main operational concern is the blockage of bottom outlets and turbine abrasion. In case of infr ...

Rapid urbanization is increasing the demand for public transport in Switzerland’s major cities. The new m3 metro line in Lausanne is planned to circulate by 2030. Its construction will require a modification of the underground flow section of the Flon Rive ...

Depending on their characteristics and management, man-made reservoirs can have a significant impact on the natural sediment continuity of rivers. We classify different reservoir types and describe potential risks for the dam and downstream river reach. Ou ...

Hydropower currently ensures two-thirds of Switzerland's domestic energy production and aims to gain more importance in the medium and long term due to nuclear abandon. In this respect, the Massongex-Bex-Rhone (MBR) run-of-river hydropower plant project on ...

The 2050 Swiss Energy Strategy aims to increase the annual production of hydroelectricity by 4% while 90% of the technically feasible potential is already used. The flexibility of high-head storage power plants (HPP), the main pillar of Swiss peak electric ...

Geomembrane systems have been used in dams and reservoirs as rehabilitation technology since several decades and are now used worldwide. They act as impervious layer to prevent and mitigate water leakage and damage to structures. They meet the needs of man ...

This paper focuses on the dynamics of fine sediments in reservoirs exposed to hydropower cascade or pumped-storage operations. The aim is at analysing the influence of parameters such as the flow inlet and flow outlet relative position, the jet hydrodynami ...

The Snowy 2.0 project is a large-scale pumped storage facility located in the Snowy Mountains in the SouthEastern part of New South Wales (Australia). It is an extension of the existing Snowy scheme, linking Tantangara (upper) and Talbingo (lower) reservoi ...

Reservoir sedimentation is one of the main challenges in the sustainable operation of large reservoirs because it causes volume loss, affecting hydropower production capacity, dam safety, and flood management. To ensure the sustainability of deep reservoir ...

Geomembrane systems have been used at hydropower plants as rehabilitation and mitigation technology for several decades and are now used worldwide. In the context of planning an energy transition that promotes the sustainable use of water resources for ene ...

In Switzerland, hydropower is the main energy source and contributes to about 58.3% of the total production. The 2050 energy strategy aims to increase this share in the coming decades. This increase is a challenge for hydropower plants. The maintenance and ...

Bien que la construction de barrages en général et l’hydraulique des barrages en particulier soient des domaines techniques très développés, le potentiel de risque associé aux barrages justifie dans la plupart des cas la vérification et l’optimisation de l ...

Les systèmes de géomembrane sont utilisés dans les aménagements hydroélectriques comme technologie de réhabilitation depuis plusieurs décennies. Dans un contexte de transition énergétique qui favorise l’utilisation durable des ressources en eau pour la pro ...
