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

Anton Schleiss, Martin Peter Bieri, Émilie Person

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 ...

Flow restoration in Alpine streams affected by hydropower operations—a case study for a compensation basin

Anton Schleiss, Martin Peter Bieri, Michael Müller

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 ...

Operation of Complex Hydropower Schemes and its Impact on the Flow Regime in the Downstream River System under Changing Scenarios

Martin Peter Bieri

Hydropower is the world’s most important renewable electricity source. More than 40% of European hydroelectric energy is produced in Alpine countries. High-head storage hydropower plants (HPP) contribute significantly to peak energy production as well as e ...

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 ...

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 ...

Lavey Dam - Physical and numerical analysis of flow and sediment transport in the Rhone River

Anton Schleiss, Martin Peter Bieri

As several of other run-of:river hydropower plants, the hydraulic scheme of Lavey on the Rhone River in Switzerland is concerned by continuous reservoir sedimentation. To determine the flood evacuation capacity of the weir as well as the flow distribution ...

Réhabilitation de la capacité d’évacuation des crues – intégration de "PK-Weirs" sur des barrages existants

Anton Schleiss, Martin Peter Bieri, Marcelo Leite Ribeiro

La réhabilitation des barrages existants impose généralement une augmentation de leur capacité d’évacuation en crue. Dans de nombreuses situations, le PK-Weir (Piano Key Weir) offre à cet égard une solution compacte et efficace. La conception et la réalisa ...

Strain-relief pattern as guide for the formation of surface-supported bimolecular nanoribbons

Martin Peter Bieri, Marta Canas Ventura

We demonstrate the suitability of the Ag/Pt(111) strain-relief pattern as efficient template for controlling the formation of well defined heteromolecular nanostructures. Two different species of molecular building blocks with complementary end-group funct ...

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

Anton Schleiss, Frédéric Jordan, Martin Peter Bieri

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 ...
