Balancing hydropeaking mitigation and hydropower production

Giovanni De Cesare, Pedro Filipe De Almeida Manso, Sabine Chamoun, Mathieu Pierre Guy Barnoud

Around 60% of Switzerland’s power production is provided by hydropower. Despite its numerous advantages, the high fluctuations in turbined discharges cause hydropeaking at downstream rivers. Due to the environmental impacts of hydropeaking on fauna and flo ...

Innovative methods to release fine sediments from reservoirs developed at EPFL, Switzerland

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

Electricity generation, water supply, flood protection, flow regulation and navigation are amongst the main services provided by reservoirs. Sedimentation affects the sustainability of reservoirs, by reducing their storage capacity, and increases the negat ...

Kariba plunge pool rehabilitation

Anton Schleiss, Giovanni De Cesare, Azin Amini, Ivan Stojnic, Claudia Ylla Arbos

The Kariba Dam is a 128 m high arch dam located on the Zambezi River, between Zambia and Zimbabwe. It forms the Kariba lake, with a surface of 5400 km2 and a capacity of 185 km3. In the 20 years following dam construction, heavy rainfalls required frequent ...

Hydromorphodynamic effects of the width ratio and local tributary widening on discordant confluences

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

River training works performed in the last couple of centuries constrained the natural dynamics of channel networks in locations that include the confluences between tributaries and main channels. As a result, the dynamics of these confluences are currentl ...

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

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

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 ...

Hydrodynamics of mountain-river confluences and its relationship to sediment transport

Mário Jorge Rodrigues Pereira Da Franca, Sebastián Guillén Ludeña

Mountain confluences are characterized by narrow and steep tributaries that provide important sediment load to the confluence, whereas themain channel supplies the dominant flow discharge. This results in a marked bed discordance between the tributary and ...

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, António Heleno Cardoso

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 ...

Hydro-morphodynamics of open-channel confluences with low discharge ratio and dominant tributary sediment supply

Sebastián Guillén Ludeña

River confluences are not only hot spots of diversity but also main elements for the connectivity in water catchments. In the past century many of the Alpine rivers in Europe as well as their tributaries have been channelized. Especially the confluences ha ...
