Flow and waves in a common tailrace channel of two pump-storage plants - physical and numerical simulation
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 high. Regarding turb ...
2012Operation of Complex Hydropower Schemes and its Impact on the Flow Regime in the Downstream River System under Changing Scenarios
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 ...

EPFL - LCH2012Discharge Capacity of Piano Key Weirs
Anton Schleiss, Martin Peter Bieri, Marcelo Leite Ribeiro
In recent years, spillway rehabilitation has increased in importance and become the subject of many projects worldwide. One solution for this problem is the implementation of a new type of labyrinth spillway, called Piano Key Weir (PK-Weir ). This is an ex ...
2012Modeling of Sediment Management for the Lavey Run-of-River HPP in Switzerland
Anton Schleiss, Martin Peter Bieri, Michael Müller
Reservoir sedimentation hinders the operation of the Lavey run-of-river hydropower plant (HPP) on the Rhone River in Switzerland. Deposits upstream of the gated weir and the lateral water intake reduce the flood release capacity and entrain sediments into ...
2012Prévision des crues sur le Yangtsé – Application du concept MINERVE
Anton Schleiss, Giovanni De Cesare, Martin Peter Bieri, Javier García Hernández, Frédéric Jordan
La gestion des eaux sur le bassin versant du fleuve Yangtsé, dont la surface représente plus de 40 fois celle de la Suisse, est indispensable pour la protection contre les crues mais aussi pour assurer les besoins d’approvisionnement de ses 300 millions d’ ...
2012Modelling and analysis of hydropeaking in alpine catchments equipped with complex hydropower schemes
Anton Schleiss, Martin Peter Bieri
High-head storage hydropower schemes in Alpine areas are required to produce peak energy and to regulate electricity grids. Nevertheless the unsteady turbine operations induce hydropeaking in the river downstream of the powerhouse. The developed hydrologic ...
2011Energy dissipation downstream of Piano Key Weirs – Case of study of Gloriettes Dam (France)
Martin Peter Bieri, Matteo Paolo Elia Antonio Federspiel
The Gloriettes concrete arch dam in the French Pyrenees showed a deficit of 80 m3/s for the new design flood of 150 m3/s. To address the problem, a Piano Key Weir (PKW) as an additional spillway was designed. The existence of a geotechnically unstable zone ...
CRC Press, Taylor & Francis Group2011Flood retention in alpine catchments equipped with complex hydropower schemes - A case study of the upper Aare catchment in Switzerland
Anton Schleiss, Martin Peter Bieri, Frédéric Jordan, Alain Fankhauser
The simulation of run-off in alpine catchment areas is an important issue for the optimal operation of hydropower plants for normal flow conditions, but also during flood events. A semi-lumped numerical approach combines hydrological modelling and operatio ...
CRC Press, Taylor & Francis Group2010Complémentarité de la modélisation physique et numérique à l’exemple d’un aménagement hydroélectrique / Complementarity of physical and numerical modeling using the example of a run-of-river hydropower plant
Martin Peter Bieri, Michael Müller
Comme beaucoup d’aménagements hydroélectriques au fil de l’eau, celui de Lavey sur le Rhône en Suisse est affecté de manière récurrente par l’alluvionnement de sa retenue. Outre la gestion sédimentaire, les thèmes abordés par la modélisation concernent éga ...
