Integrating the Finite Element Method with a Data-Driven Approach for Dam Displacement Prediction

Both numerical simulations and data-driven methods have been applied in dam's displacement modeling. For monitored displacement data-driven methods, the physical mechanism and structural correlations were rarely discussed. In order to take the spatial and ...

Advances in dam construction techniques have significantly increased the number of implemented stepped spillways worldwide. A key hydraulic feature of a stepped chute, compared to a smooth chute, is the enhanced energy dissipation resulting in a reduced re ...

Hydraulic Reconstruction of the 1818 Gietro Glacial Lake Outburst Flood

Christophe Ancey, Tomás Alfredo Trewhela Palacios, Eric Bardou, Martin Funk

In the spring of 1818, ice avalanches from the Gietro Glacier created an ice dam, which in turn formed a glacial lake in the Drance Valley (Canton of Valais, Switzerland). Today, its maximum volume is estimated to have been 25x10(6) m(3). Cantonal authorit ...

Computational modelling of fine sediment release using SEDMIX device with thrusters

Giovanni De Cesare, Azin Amini, Arianna Yadira Onate Paladines

Problem: Reservoir sedimentation occurs in dams worldwide, reducing the live storage available in the reservoirs. Possible solution: Jenzer-Althaus 2011) testes a water stirring device (called SEDMIX) that keeps sediments in suspension, enhancing its relea ...

Heightening of very high gravity dams: the case study of the Grande Dixence

Giovanni De Cesare, Pedro Filipe De Almeida Manso, Basile Clerc

Dam heightening can provide large incremental positive impacts on storage with minimum incremental negative impacts, but requires deep knowledge of the structure and its foundation. Very high gravity dams are usually well studied and documented due to thei ...

Risk assessment of dam's running status is an important part of dam management. A data-driven method based on monitored displacement data has been applied in risk assessment, owing to its easy operation and real-time analysis. However, previous data-driven ...

Effect of building overtopping on induced loads during extreme hydrodynamic events

Anton Schleiss, Michael Pfister, Davide Wüthrich, Ioan Nistor

Tsunamis, impulse-waves and dam-break waves have affected humanity in recent decades and the construction of vertical shelters can provide safety to people. However, for non-critical infrastructures, typically residential houses of lower height, overtoppin ...

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 ...

Micromechanical controls of mixed-mode anticrack nucleation in porous solids: application to snow failure

Johan Alexandre Philippe Gaume, Henning Löwe, Jonas Ritter

Porous cohesive materials can fail and collapse under compressive stresses. This mechanical behavior is generally referred to as anticrack and in snow, it is at the origin of catastrophic avalanches. In this study, we investigate how the microstructure of ...

Dam safety is strongly linked to the probability of occurrence of large floods. Floods can transport large wood (LW) into reservoirs and towards water release structures as spillways. Due to blocking and clogging, LW may significantly influence the dischar ...
