Mitigation of impact of a major benzene spill into a river through flow control and in-situ activated carbon absorption

Benzene is a toxic contaminant and can harm many aquatic species and cause serious damages to the river eco-system, if released to rivers. In 2012, a major spill accident occurred on the Huaihe River in Eastern China with 3 tons of benzene released to the ...

Small Flex : Modèle d’exploitation flexible d’aménagements hydroélectriques de haute chute au fil de l’eau en Valais

Baku Mbenza

The Kraftwerk Rhone Oberwald hydropower was selected as a pilot site to analyze the possibility of running hydropower plants along a river in alpine regions during winter months. The KRO Gletsch-Oberwald hydropower facility has been operating since the beg ...

Delineating the Continuum of Dissolved Organic Matter in Temperate River Networks

Luis Gómez Gener

The origin and reactivity of dissolved organic matter (DOM) have received attention for decades due to the key role DOM plays in global carbon cycling and the ecology of aquatic systems. However, DOM dynamics in river networks remain unresolved, hampered b ...

Design of Riverbank Riprap Using Large, Individually Placed Blocks

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

The protection of river banks in mountain rivers by riprap requires large blocks with weights typically exceeding 1 t. Thus, the blocks have to be placed individually. Such packed riprap has a relatively small spacing between the blocks. Consequently, the ...

Pioneer plant Phalaris arundinacea and earthworms promote initial soil structure formation despite strong alluvial dynamics in a semi-controlled field experiment

Claire Guenat, Pascal Turberg, Renée-Claire Le Bayon, Andreas Cedric Schomburg, Muhammad Riaz

Soil structure formation is among the most important processes in riverfloodplains which are strongly influ-enced by alluvial dynamics. In the context of river restoration projects, a better understanding of soil structureformation in habitats adjacent to ...

Subaquatic slope instabilities: The aftermath of river correction and artificial dumps in Lake Biel (Switzerland)

Alfred Johny Wüest, Laëtitia Meuriot, Nathalie Dubois

River engineering projects are developing rapidly across the globe, drastically modifying water courses and sediment transfer. Investigation of the impact of engineering works focuses usually on short-term impacts, thus a longer-term perspective is still m ...

Recent developments on management and release techniques of fine sediments in reservoirs

Anton Schleiss

Sedimentation is known as the process of filling up natural lakes and manmade reservoirs by sediment transforming finally into floodplaimns. Its main reason is the sediment yield transported by rivers as suspended or bed load into the reservoirs. Reservoir ...

Sediment flushing downstream dams: a study on the clogging by fine sediments

Giovanni De Cesare, Christophe Ancey, Romain Maxime Dubuis

Water reservoirs used to produce electricity have an impact on the environment and durability by : • stopping the natural sediment flux • changing the flow regime downstream of the reservoirs • storing (fine) sediments that reduce the storage volume Those ...

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 ...

Alpine hydropower plants renewal : synergies between flexible production and hydropeaking mitigation

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

Hydropeaking is the water flow or level variations in rivers caused by hydropower exploitation. This phenomenon have negatives impacts on fauna and flora. Mitigation measures can lead to producing less and reduce production at the times that are most econo ...
