Water retention in reservoirs and concentrated turbine operations allow electricity to be produced on demand. Sudden opening and closing of the turbines can produce highly unsteady flow conditions in the river downstream of the tailrace channel, the so-cal ...

Impact du retrait glaciaire et adaptation du potentiel hydroélectrique dans les Alpes suisses

Anton Schleiss, Martin Peter Bieri, Frédéric Jordan, Stéphane Christian Olivier Terrier

Le réchauffement climatique est une réalité alarmante et conduit probablement à une augmentation de la pression sur les systèmes socio‑économiques. Cependant, dans les régions de haute‑montagne, il pourrait induire l’opportunité d’adapter des aménagements ...

Mitigation measures for fish habitat improvement in Alpine rivers affected by hydropower operations

Anton Schleiss, Martin Peter Bieri, Émilie Person, Armin Julius Peter

In mountainous areas, high-head-storage hydropower plants produce peak load energy. The resulting unsteady water release to rivers, called hydropeaking, alters the natural flow regime. Mitigating the adverse impacts of hydropeaking on aquatic ecosystems ha ...

Optimization of a Shared Tailrace Channel of Two Pumped-Storage Plants by Physical and Numerical Modeling

Giovanni De Cesare, Martin Peter Bieri, Stéphane Christian Olivier Terrier, Sylvain Candolfi

Pump and turbine operations lead to head losses in the tailrace channel. Pumping discharge may be limited due to potential air entrainment into the pump shaft when the downstream reservoir is at its lowest level and the head losses are too high. Regarding ...

Surge Wave Propagation in a Common Tailrace Channel for Two Large Pumped-Storage Plants

Anton Schleiss, Giovanni De Cesare, Martin Peter Bieri, Stéphane Christian Olivier Terrier

Sudden starting and stopping of turbines and pumps lead to highly unsteady flow in tailrace channels of hydropower plants (HPP). Submergence of Pelton turbines and air entrainment in pumps due to surge waves must be avoided by technical measures. The exist ...

Hydropeaking, resulting from rapid starting and shut-down of turbines, is one of the major hydrological alterations in Alpine streams. The upper Aare River basin in Switzerland comprises a complex high-head storage hydropower scheme. The significant turbin ...

The simulation of run-off in Alpine catchment areas is essential for the optimal operation of high head storage hydropower plants (HPPs) under normal flow conditions, but also in case of flood events. A conceptual semidistributed numerical approach is pres ...

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 ...

Das revidierte Gewässerschutzgesetz schreibt für Schwall-und Sunk-beeingträchtigte Gewässer eine Sanierung des Abflussregimes vor. Um Massnahmen in komplexen Kraftwerkssystemen wirtschaftlich und ökologisch zu beurteilen, ist ein interdisziplinärer Ansatz sinnvoll. Der Betrieb des Kraftwerks wird mit dem Softwaretool Routing System simuliert. Daraus resultiert die Ganglinie im Fluss sowie die durch die zu testende Sanierungsmassnahme entstandenen Kosten. Die Beurteilung der Bachforellenhabitate berücksichtigt nebst den kritischen Entwichlungsstadien der Forelle auch den Einfluss der Gerinnmorphologie.

Influence of climate change on future operation of a complex storage hydropower scheme in the Swiss Alps

Anton Schleiss, Martin Peter Bieri

For the case study area of the upper Aare River catchment in Switzerland with large mountain glaciers, where a complex storage hydropower scheme is located, the impact of climate change on runoff was simulated. Future runoff was assessed for the ongoing ce ...
