Effect of blocked driftwood on the hydraulic performance of a gated standard weir
Giovanni De Cesare, Michael Pfister, Loïc Bénet
Driftwood belongs to riverine ecosystems and is stored and transported in every natural stream. Hydraulic structures built in streams typically alter the flow characteristics and might consequently get in conflict with driftwood. The latter can get trapped ...
International Association for Hydro-Environment Engineering and Research (IAHR)2022Experimental 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 ...
2021Reservoir Level Rise under Extreme Driftwood Blockage at Ogee Crest
Giovanni De Cesare, Michael Pfister, Loïc Bénet
Dams are civil structures essential to modern civilization. However, they can be a threat if not properly designed and operated. A particular risk that potentially can lead to dam failure is the blocking of the spillway inlet with driftwood or debris. This ...
2021Stilling Basin Performance Downstream of Stepped Spillways
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 ...
EPFL2020Effect of 30-Degree Sloping Smooth and Stepped Chute Approach Flow on the Performance of a Classical Stilling Basin
Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Ivan Stojnic
Advances in dam construction techniques have significantly increased the number of stepped spillways implemented worldwide. Although stepped chutes provide enhanced energy dissipation along the chute, as compared to smooth chutes, an adequate energy dissip ...
2020Bottom pressure characteristics in a stilling basin downstream of a stepped spillway for two different chute slopes
Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Ivan Stojnic
In the last decades numerous stepped spillways were built, mostly on the downstream face of roller compacted concrete (RCC) dams. Stilling basins are often used as an energy dissipater. Although the hydraulics of stepped chutes was extensively investigated ...
The University of Queensland2020Kariba 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 ...
2018Hybrid Modelling Approach to Study Scour Potential at Chancy-Pougny Dam Stilling Basin
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 inauguration, the operation of the four spillway gates was responsible for a progressive erosion of the stilling basin. Thus, a hybrid modelling was pe ...
Springer2018Influence of density of large stems on the blocking probability at spillways
Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Paloma Furlan
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 ...
