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 ...

Plunging Circular Jets: Experimental Characterization of Dynamic Pressures Near the Stagnation Zone

Gregoire Aurelien Marie Jamet, Giovanni De Cesare, Pedro Filipe De Almeida Manso

Spillways are a requirement for dams’ safety, mainly preventing overtopping during floods. A common spillway solution involves plunging jets, which dissipate a considerable flow energy in the plunge pool. Energy dissipation has to occur in a controlled man ...

Experimental and numerical investigations of a high-head pumped-storage power plant at speed no-load

François Avellan, Pedro Filipe De Almeida Manso, Vlad Hasmatuchi, Cécile Münch-Alligné

Due to the increasing integration of new renewable energies, the electrical grid undergoes more frequent instabilities. Hydroelectric power plants, particularly pumped storage plants, are well suited for grid control. However, this objective requires exten ...

One-dimensional fluid–structure interaction models in pressurized fluid-filled pipes: a review

Anton Schleiss, Pedro Filipe De Almeida Manso

The present review paper aims at collecting and discussing the research work, numerical and experimental, carried out in the field of Fluid–Structure Interaction (FSI) in one-dimensional (1D) pressurized transient flow in the time-domain approach. Backgrou ...

Improving hydropower flexibility by synergizing independently managed utilities

Giovanni De Cesare, Pedro Filipe De Almeida Manso, Sabine Chamoun

Increasing the flexibility of hydropower allows operators to produce at optimal time ranges, not only dependent on the demand flow but also on the price trends. However, the possibility to improve hydropower flexibility can be hindered when assets are mana ...

Computational hydraulic modelling of fine sediment stirring and evacuation through the power waterways at the Trift reservoir

Anton Schleiss, Pedro Filipe De Almeida Manso, Azin Amini, Célestin Leupi, Sara Venuleo

Taking advantage of the withdrawal of some glaciers, several new dams will eventually be constructed in Switzerland in the coming years as a part of the 2050 energy strategy. The Trift dam, located in Berner Oberlands in Switzerland, is one of these new pr ...

Overflow pressure characterization in lined plunge pools for slab sizing

Giovanni De Cesare, Pedro Filipe De Almeida Manso

This study presents an experimental work on dynamic pressures at the bottom of a lined plunge pool that receives overflow rectangular impinging jets and aims at improving the design criteria for pool slabs. The experiments were conducted in a fairly large ...

Laboratory research: bed load guidance into sediment bypass tunnel inlet

Anton Schleiss, Giovanni De Cesare, Pedro Filipe De Almeida Manso, Milad Daneshvari

Sediment management in reservoirs situated in mountainous regions is a critical operational concern with direct implications in live storage sustainability and therefore in production revenues. The paper presents the main results of a physical model study ...

Seismic Behavior of Pine Flat Concrete Gravity Dam Using Microplane Damage-Plasticity Model

Giovanni De Cesare, Pedro Filipe De Almeida Manso, Samuel Luke Vorlet

The response of concrete gravity dams under seismic loads is a major concern of dam safety assessment in earthquake-prone areas. This study focuses on the seismic analysis of the tallest non-overflow monolith of Pine Flat Dam. The paper presents results of ...

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 ...

Swiss Potential for Hydropower Generation and Storage - Synthesis report

François Avellan, Pedro Filipe De Almeida Manso, Paolo Burlando

Hydropower (HP) is the backbone of the Swiss electricity system providing around 60 % (36 TWh/a) of the total electricity generated on a yearly average. With the planned phase-out of nuclear power plants, HP and other Renewable Energy Sources (RES) will ne ...

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 ...
