Numerical Modeling of turbidity currents with Ansys CFX and Telemac 3D

Giovanni De Cesare, Anton Schleiss, Sabine Chamoun

Turbidity currents may be a relevant lever to manage the accumu-lation of fine sediments in reservoirs. In this paper, we propose to show how two different numerical codes simulate the propagation of turbidity currents. Telemac 3D and Ansys CFX 17.1 solver ...

Kariba plunge pool rehabilitation

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

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 ...

Experimental repetitions and blockage of large stems at ogee crested spillways with piers

Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos, Michael Pfister, Paloma Furlan

Large wood is often transported by rivers into reservoirs during heavy rainfall events. When a critical section like a spillway is blocked and discharge capacity reduced, an uncontrolled increase of the reservoir water level may occur. This study aims to s ...

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 ...

Influence of Operational Timing on the Efficiency of Venting Turbidity Currents

Giovanni De Cesare, Anton Schleiss, Sabine Chamoun

Reservoir sedimentation is gaining growing attention as dams are aging, due to economic and environmental consequences. Venting of turbidity currents is one of many sediment management techniques, highly recommended when water is in shortage. The venting o ...

Neues Konzept für teildurchgängige Geschiebesammler mit sicherem Rückhalt

Anton Schleiss, Sebastian Schwindt

Geschieberückhalt in stark sedimentführenden Gewässern ist im alpinen Raum elementar für den Hochwasserschutz, jedoch unzuträglich für die natürliche Flussmorphologie und aquatische Lebewesen im Unterlauf. Mit systematischen Versuchen wurde ein neues Konze ...

Analysis of the sensitivity of the hydromorphological index of diversity, HMID

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

Hydromorphological conditions are a key factor for the habitat diversity in riverine ecosystems. The Hydromorphological Index of Diversity (HMID) is a tool to quantify the habitat diversity in a river reach based on local flow depths and flow velocities. T ...

Dimensionnement des orifices pour étranglement des cheminées d’équilibre

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

Les orifices sont utilisés dans divers domaines de l’hydraulique par exemple pour des étranglements au pied de cheminées d’équilibre sans modification constructive de la cheminée d’équilibre. Dans ce cas, un orifice permet d’adapter un aménagement hydroéle ...

Experiments with sediment replenishment in a residual flow reach: Comparison of field datawith laboratory experiments

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

Hydropower is an important pillar of the electricity production in Switzerland and its extension is planned in the next decades. Therefore, a more sustainable management of hydropower plants is needed. Sediment replenishment combined with artificially-trig ...

Design optimization of permeable sediment traps for fluvial bed load transport

Anton Schleiss, Mona Jafarnejad Chaghooshi, Sebastian Schwindt, Anita Hélène Roth

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 ...
