Feinsedimentdynamik in revitalisierten Flüssen

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez, Matthias Thalmann

Im Rahmen von Flussrevitalisierungen werden oftmals seitliche Aufweitungen geschaffen, in denen sich Feinsedimente ablagern können. Insbesondere in Flüssen, die von Schwall und Sunk betroffen sind, stellt sich die Frage, wie der Ablagerungsprozess von Fein ...

Influence of lateral embayments on suspended sediment transport under unsteady flow conditions

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez, Matthias Thalmann

Local widening in a channelized river is a common practice in restoration projects. The lateral embayments built for this purpose in the river banks are partially filled up by fine sediments. This allows the formation of aquatic habitats with hydraulic and ...

Le transit des courants de turbidité, une technique pour réduire l’alluvionnement des réservoirs de barrages

Giovanni De Cesare, Anton Schleiss, Sabine Chamoun

La sédimentation des réservoirs est une problématique globale réduisant le volume d’eau disponible dans les réservoirs de barrages et induisant des pertes aux niveaux énergétique, économique et environnemental. Le transport de sédiments du bassin versant p ...

Experimental Study of Tsunami-Like Waves Generated with a Vertical Release Technique on Dry and Wet Beds

Anton Schleiss, Michael Pfister, Davide Wüthrich, Ioan Nistor

Tsunamis, impulse waves, and dam failures are disasters that challenge humanity, often leading to massive casualties and extreme economic losses. The highly unsteady flow conditions generated by such events are often in the form of turbulent bores. The pur ...

The safety challenge of river diversion during construction of dams

Anton Schleiss

The appropriate design of a river diversion system during construction of dam is an essential task since dramatic consequences in view of cost and time overrun may be involved. After a short outline of the different methods of river diversion and its main ...

Sampling sufficiency for determining hydraulic habitat diversity

Anton Schleiss, Walter Gostner, Mário Jorge Rodrigues Pereira Da Franca, Christopher Robinson, Severin Stähly

The geometry and hydrodynamics of river reaches are key ecohydraulic descriptors. Statistics of water depth and velocity measurements are usually taken as proxies for habitat suitability in rivers. However, little is known about the sufficiency of data to ...

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 ...

The role of uncertainty in dam failure frequency estimates: a conceptual case study

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos

The return period of combinations of events that are relevant to dam risk analysis is very high. It falls in a range of hundreds to millions of years, but remains hard to quantify with precision. Deterministic approaches to dam safety assessment typically ...

Wave impact on oriented impervious buildings

Anton Schleiss, Michael Pfister, Davide Wüthrich, Claudia Ylla Arbos

Recent studies showed that a speciﬁc design can reduce the impact of water waves on structures, thus limiting the damages. Herein the impact of waves on buildings is addressed, pointing out the inﬂuence of orientation on the hydrodynamic process. ...

Information-gap decision theory (IGDT): a new promising method for management of uncertainties in hydropower projects: case study

Anton Schleiss, Felix Oberrauch

The design of hydropower is determined by estimates and long-term forecasts. These forecasts and estimates are highly uncertain and make performance evaluation and design choices challenging. Effective values deviating from the estimates can have a signifi ...

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 hydropower-Europe forum and the technology roadmap

Anton Schleiss

A new EU initiative, Hydropower-Europe, is reported here. This work, soon to be launched, will provide a framework for the hydropower sector in Europe to define a research and innovation agenda, and technology roadmap. The initiative is expected to help po ...

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 Rainfall Mass Curves and their Influence on Extreme Flood Simulation

Bettina Schaefli, Anton Schleiss, Javier García Hernández, Fränz Zeimetz, Guillaume Mathieu Artigue

Extreme flood estimates for dam safety are routinely obtained from hydrologic simulations driven by selected design storms. The temporal structure of such design storms can be obtained from Rainfall Mass Curves (RMCs), which are adimensionalized curves of ...

Entrainment, transport and deposition of sediment by saline gravity currents

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Jessica Zordan, Carmelo Juez Jiménez

Few studies have addressed simultaneously the feedback between the hydrodynamics of a gravity cur- rent and the geomorphological changes of a mobile bed. Hydrodynamic quantities such as turbulent and mean velocities, bed shear stress and turbulent stresses ...

Design of a Throttled Surge Tank for Refurbishment by Increase of Installed Capacity at a High-Head Power Plant

Giovanni De Cesare, Bernard Valluy, Anton Schleiss, Nicolas Jean François Pascal Ghislain Adam

The Swiss confederation aims to phase out nuclear power production with its Energy Strategy 2050 program by increasing the renewable energy contribution to its overall energy generation. Hydroelectricity, which is the most important form of renewable energ ...

Investigation of local scour around tandem piers for different skew-angles

Giovanni De Cesare, Anton Schleiss, Sargol Memar

In the present study the effect of the skew-angle of the alignment of tandem piers on local scour depth around them is investigated. The tandem piers were aligned with different skew-angles of 𝜃𝜃 = 0°, 30°, 45°, 60°, 90° with respect to the flow direction. ...
