EFFECT OF THE BED LOAD GRADATION ON THE MORPHODYNAMICS OF DISCORDANT CONFLUENCES

António Heleno Cardoso, Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña

Within the fluvial network, river confluences are particular areas characterized by complex hydrodynamic, morphodynamic and sedimentary processes. These processes have been observed to be governed by parameters such as the discharge ratio, the junction ang ...

Estimation of wave propagation velocity on a channel with smooth and rough bed

Anton Schleiss, Michael Pfister, Davide Wüthrich, Ioan Nistor

Natural hazards such as tsunamis, impulse waves and dam-break waves are rare, but extremely destructive. In recent times, more importance was given to structures that could withstand such events, however, uncertainties still exist in the estimation of wave ...

Head losses and influence length of sharp-edged and rounded orifices under steady flow conditions

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

Orifices have been largely studied either for flow metering or for producing head losses. An orifice which is used as a flow meter is well defined in ISO 5167. All the geometrical parameters are defined to obtain discharges as accurate as possible. However ...

Time-based failure analysis of compressed riverbank riprap

Charles Pfister, Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Mona Jafarnejad Chaghooshi

Methods to design riprap-lined channels usually refer to dumped material. Large blocks placed individually by machinery are used when more stability is required. They offer additional resistance against flow erosion since space between blocks is minimized ...

Relevance of the correlation between precipitation and the 0 C isothermal altitude for extreme flood estimation

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

Extreme floods are commonly estimated with the help of design storms and hydrological models. In this paper, we propose a new method to take into account the relationship between precipitation intensity (P) and air temperature (T) to account for potential ...

Investigation of venting turbidity currents in the Rudbar-Lorestan reservoir in Iran

Giovanni De Cesare, Anton Schleiss, Azin Amini, Sabine Chamoun, Sara Venuleo

Venting of turbidity currents is known as an efficient measure to prevent reservoir sedimentation and is applied in many reservoirs globally. It has several economic and ecological advantages compared with other evacuation methods. In the literature, numer ...

Fluid–structure interaction in pipe coils during hydraulic transients

Anton Schleiss, Pedro Filipe De Almeida Manso, David Ferràs Segura

The paper presents the analysis of fluid–structure interaction occurring during hydraulic transients in pipe coils by means of a four-equation model. The purpose is to understand and describe the effect of the coil movement on the transient wave. The four- ...

Assessment of hydropower potential in wastewater systems and application to Switzerland

Philippe Heller, Luca Rossi, Anton Schleiss, Pedro Filipe De Almeida Manso, Irene Almeida Samora

Energy recovery through local hydropower generation is a way of coping with high electricity expenditures in wastewater systems (WWS). Installing small hydropower plants within WWS is already in some countries eligible for incentive policy mechanisms to re ...

Impacts du changement climatique sur la production hydroélectrique alpine : comment une nouvelle retenue à Oberaletsch pourrait garantir la gestion durable des installations existantes

Anton Schleiss, Pedro Filipe De Almeida Manso, Jonathan Fauriel, Fränz Zeimetz

Suite à décision du Conseil Fédéral de sortir du nucléaire, l’hydroélectricité suisse jouera un rôle central pour réussir la transition énergétique. Cependant, le changement climatique semble avoir un impact négatif sur la production hydraulique à long ter ...

Stress intensity factors for axial semi-elliptical surface cracks and embedded elliptical cracks at longitudinal butt welded joints of steel-lined pressure tunnels and shafts considering weld shape

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

When for steel liners of pressure tunnels and shafts high-strength steels are used, welded joints are subject to the risk of hydrogen induced cold-cracking in the base material. Longitudinal butt welded joints are critical regions as they are loaded transv ...

Management of turbidity current venting in reservoirs under different bed slopes

Giovanni De Cesare, Anton Schleiss, Sabine Chamoun

The lifetime and efficiency of dams is endangered by the process of sedimentation. To ensure the sustainable use of reservoirs, many sediment management techniques exist, among which venting of turbidity currents. Nevertheless, a number of practical questi ...

EXPERIMENTAL RESULTS ON SEDIMENT ENTRAINMENT BY GRAVITY CURRENTS

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

Gravity currents are geophysical flows responsible of the distal transport of high volumes of sediments. In particular, turbidity currents, a form of gravity currents where sediments in suspension confer the buoyancy that ignites the flow, are the main mec ...

SENSITIVITY ANALYSIS OF THE HYDROMORPHOLOGICAL INDEX OF DIVERSITY USING NUMERICAL GENERATED DATA

Anton Schleiss, Christopher Robinson, Pierre Bourqui, Severin Stähly

River restoration has become a priority goal in many countries. The interest in rivers as valuable habitats for floral and faunal diversity and as an ecosystem with important functions has increased. For evaluating the structural changes from a river resto ...

Probabilistic failure analysis of riprap as riverbank protection under flood uncertainties

Eugen Brühwiler, Anton Schleiss, Mona Jafarnejad Chaghooshi, Michael Pfister

Existing riverbank riprap could face the risk of failure if the flood regime changes in future. Additionally, changed sediment transport in rivers, as a possible result of climate change, impacts the failure risk of flood protection measures. Evaluation of ...

Modeling sediment pulses on an armored channel

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Elena Battisacco, Carmelo Juez Jiménez

Dams trap sediments in the upstream reservoir, thus the continuity in sediment transport along the river is interrupted. Several negative aspects related to the lack of sediment supply were observed downstream many dams and the artificial replenishment of ...
