Evolution of reservoir flushing and emptying practices in a cascade of large reservoirs across several decades

Giovanni De Cesare, Pedro Filipe De Almeida Manso, Samuel Luke Vorlet, Sebastián Guillén Ludeña

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 ...

Sediment balance of a cascade of alpine reservoirs based on multi-decadal data records

Anton Schleiss, Pedro Filipe De Almeida Manso, Sebastián Guillén Ludeña

Reservoir sedimentation is a major concern in the operational management of dams and appurtenant structures. The increasing volume of sediments deposited in reservoirs leads to a loss of water storage, undermining the purpose itself of the dam for human us ...

Advanced models for stress evaluation and safety assessment in steel-lined pressure tunnels

Anton Schleiss, Pedro Filipe De Almeida Manso, Alexandre Jean Pachoud

An accurate estimation of the stress in a steel liner is required for the design of steel-lined pressure shafts, both with regard to safety assessment of ageing steel-lined waterways of hydropower plants built in the 20th century, and for new projects whic ...

The role of glacier retreat for Swiss hydropower production

Pedro Filipe De Almeida Manso, Bettina Schaefli

High elevation or high latitude hydropower production (HP) strongly relies on water resources that are influenced by glacier melt and are thus highly sensitive to climate warming. Despite of the wide-spread glacier retreat since the development of HP infra ...

Parametric study on the influence of jet-like inflows and outflows on fine sediment settling

Anton Schleiss, Pedro Filipe De Almeida Manso, Samuel Luke Vorlet

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 ...

Innovative methods to release fine sediments from seasonal reservoirs

Anton Schleiss, Giovanni De Cesare, Pedro Filipe De Almeida Manso, Azin Amini, Sabine Chamoun, Sebastián Guillén Ludeña

The papers present three innovative solutions for fine sediment manage- ments in seasonal reservoirs, which are at different stages of maturity. Operational reservoir stirring using jet-like inflows may facilitate sediment routing, at no addi- tional cost ...

Charting the course: A possible route to a fully renewable Swiss power system

Michael Lehning, Pedro Filipe De Almeida Manso, Jérôme François Sylvain Dujardin, Albertus Christiaan Kruyt, Annelen Kahl, Stuart John Bartlett

The prospect of a renewable transition seems plausible for many countries, but can be shrouded in risks, costs and challenges. This paper illuminates a path for such a transition with a numerical investigation, aimed at resolving the power dynamics of a co ...

Multidecadal sediment balance modelling of a cascade of alpine reservoirs and perspectives based on climate warming

Anton Schleiss, Pedro Filipe De Almeida Manso, Sebastián Guillén Ludeña

This paper presents a comprehensive methodology to model and determine the annual sediment balance of a complex system of interconnected reservoirs, based on the detailed interpretation of a multi-decadal data series of reservoir management and modelling o ...

Alpine hydropower production and glacier retreat: the case of Switzerland

Pedro Filipe De Almeida Manso, Bettina Schaefli

Hydropower production (HP) in high mountainous areas relies on snow- and glacier melt influenced water resources and is thus highly sensitive to climate warming. Based on the case of Switzerland that produces over 50% of its electricity from hydropower, we ...

Behaviour of a scour protection overlay with randomly distributed concrete prisms in plunge pools downstream of mobile barrages for exceptional operation conditions

Anton Schleiss, Giovanni De Cesare, Pedro Filipe De Almeida Manso, Sabine Chamoun, Davide Wüthrich

Uncontrolled scour is affecting multiple mobile dams. The plunge pool of the Chancy-Pougny barrage, located on the Rhone River bordering France and Switzerland, has recently been reported to develop in a potentially unfavourable direction after almost 100 ...
