Assessing the potential increase of seasonal energy storage to mitigate the impact of climate change in Switzerland: Case study of the Grande Dixence dam

Anton Schleiss, Pedro Filipe De Almeida Manso, Jérôme François Sylvain Dujardin

The total storage capacity of the reservoirs in Switzerland represents only 42% of their annual production of electricity, but secures approximately 100% of hydropower’s contribution to the winter electricity supply. In order to avoid spilling, the storage ...

INVESTIGATION OF TURBIDITY CURRENT VENTING FOR TWO DIFFERENT RESERVOIR BED SLOPES

Anton Schleiss, Giovanni De Cesare, Sabine Chamoun

Reservoirs represent an important source of energy that should be preserved and sustained. However, the lifetime of reservoirs is being reduced due to natural processes such as sedimentation. To face this problem, different sediment mitigation techniques a ...

Design optimization of permeable sediment traps for fluvial bed load transport

Anton Schleiss, Sebastian Schwindt, Mona Jafarnejad Chaghooshi

Sediment traps are crucial elements for flood protection in mountain rivers with high sediment transport capacity. Existing structures often interrupt the channel connectivity. Ideally, a sediment trap should be permeable for bed load during non-hazardous ...

Influence of geometry shape factor on trapping and flushing efficiencies

Anton Schleiss, Sameh Ahmad Kantoush

The trap efficiency of a shallow reservoir depends on the characteristics of the inflowing sediments and the retention time of the water in the reservoir, which in turn are controlled by the reservoir geometry. With the purpose of controlling the trapped a ...

Hydro‐morphodynamic evolution in a 90° movable bed discordant confluence with low discharge ratio

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

Confluences with low discharge and momentum ratios, where narrow steep tributaries with high sediment load join a wide low-gradient main channel that provides the main discharge, are often observed in high mountain regions such as in the upper- Rhone river ...

Sediment replenishment: Influence of the geometrical configuration on the morphological evolution of channel-bed

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Elena Battisacco

Dams trap sediment in the upstream reservoir, which may lead to river bed armoring, streambank erosion and failure, channel incision and reduction of the morphological diversity in the downstream river reaches. The replenishment of sediment is a mitigation ...

Sediment replenishment combined with an artificial flood improves river habitats downstream of a dam

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Severin Stähly

River reaches downstream dams where a constant residual flow discharge is imposed, often lack sediment supply and periodic inundation due to the absence of natural flood events. In this study, a two-year return flood was released from an upstream reservoir ...

Physical modelling of artificial river replenishment techniques to restore morphological conditions downstream of dams

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Elena Battisacco

First applied in the 1980’s, the artificial replenishment of sediments is one technique proposed to solve the problem of sediment deficit downstream dams. The present experimental research aims at improving the technique of river replenishment and at provi ...

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

Anton Schleiss, Giovanni De Cesare, 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 ...

Effect of debris damming on wave-induced hydrodynamic loads against free-standing buildings with openings

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

Tsunamis, impulse waves, and dam-break waves are rare but catastrophic events, associated with casualties and damage to infrastructures. An adequate description of these waves is vital to assure human safety and to generate resilient structures. Furthermor ...

Influence of jet aeration on pressures around a block embedded in a plunge pool bottom

Anton Schleiss, Rafael Xavier Meriade Duarte

The influence of the air entrained by water jets on the dynamic pressures applied on the bottom of a plunge pool and inside underlying fissures was analyzed with systematic experiments. The large experimental facility reproduced aerated high-velocity jets ...

Design of sediment detention basins: Scaled model experiments and application

Anton Schleiss, Sebastian Schwindt, Mona Jafarnejad Chaghooshi

Sediment detention basins are implemented on mountain rivers to trap solid material that may aggravate the flooding of downstream settlements. However, retention structures built in the past may unnecessarily retain sediment during non-hazardous flood even ...

Transport of suspended sediments under the influence of bank macro-roughness

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

River restoration works often include measures to promote morphological diversity and enhance habitat suitability. One of these measures is the creation of macro-roughness elements, such as lateral cavities and embayments, in the banks of channelized river ...

Sediment Evacuation from Reservoirs through Intakes by Jet-Induced Flow

Anton Schleiss, Giovanni De Cesare, Jolanda Maria Isabella Jenzer Althaus

Reservoir sedimentation is considered as a sustainability problem. A concept getting down to the root of the cause was developed and tested in laboratory experiments. The idea is to maintain sediment in suspension, i.e., avoiding its settling near the dam ...

Experimental evaluation of the discharge capacity of flow constrictions by check dams in mountain rivers

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastian Schwindt

Open check dams are built to retain bed load in case of major floods and may have filtering, sieving as well as dosing effects on sediment transport. The combination of an upstream reservoir with an open check dam is designated as bed load trap. These stru ...

Experimental and Numerical Study on Scour-Protection Methods in a Stilling Basin: Case Study of Chancy-Pougny Dam

Anton Schleiss, Giovanni De Cesare, Erik Bollaert, Sabine Chamoun, Davide Wüthrich

Chancy-Pougny is a run-of-river dam on the Swiss–French border constructed in the early 1920s. Since its commissioning, the operation of the four spillway gates has been responsible for a progressive erosion of the stilling basin. The future scour potentia ...

Sediment replenishment as a measure to enhance river habitats in a residual flow reach downstream of a dam

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Severin Stähly

Floodplains downstream of a dam, where the natural flow regime is replaced by a constant residual flow discharge, often lack sediment supply and periodic inundation due to the absence of natural flood events. In this study, a flood with a one-year return p ...

Influence of the convergence angle on the morphodynamics of discordant bed confluences

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

Within the fluvial network, confluences are particular areas characterized by great ecological value where flow dynamics and bed morphology are much influenced by local patterns. The aim of this article is to describe the influence of the convergence angle ...

Temporal evolution of bedload in a steep channel over a long duration experiment

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Tamara Ghilardi

Bedload fluctuations over time in steep rivers with wide grain size distributions have been observed, even under constant sediment feeding and water discharge. Observed bedload pulses are periodical and a consequence of grain sorting. Along with bedload, f ...
