Advances in Spillway Hydraulics: From Theory to Practice
Anton Schleiss, José Pedro Gamito de Saldanha Calado Matos
Over the past decades, significant advances have been achieved in hydraulic structures for dams, namely in water release structures such as spillway weirs, chutes, and energy dissipators. This editorial presents a brief overview of the eleven papers in thi ...
2023Experimental investigations on plunge pool protection measures for Ilarion Dam in Greece
Anton Schleiss, Giovanni De Cesare, Azin Amini, Romain Nathan Hippolyte Merlin Van Mol
Ilarion Dam is a 130 m high earthfill dam at Aliakmon River in northern Greece. The dam was commissioned in 2010. It has two spillway tunnels with ski jumps at the outlets. The two spillways are designed to release a total discharge of 5'500 m3/s during th ...
2022Performance and Design of a Stepped Spillway Aerator
Anton Schleiss, Michael Pfister, Stéphane Christian Olivier Terrier
Stepped spillways are frequently limited to specific discharges under around 30 m2/s due to concerns about potential cavitation damages. A small air concentration can prevent such damages and the design of bottom aerators is well established for smooth chu ...
2022Effect 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)2022Plunging Circular Jets: Experimental Characterization of Dynamic Pressures Near the Stagnation Zone
Giovanni De Cesare, Pedro Filipe De Almeida Manso, Gregoire Aurelien Marie Jamet
Spillways are a requirement for dams’ safety, mainly preventing overtopping during floods. A common spillway solution involves plunging jets, which dissipate a considerable flow energy in the plunge pool. Energy dissipation has to occur in a controlled man ...
2022Blockage Probability Modeling of Large Wood at Reservoir Spillways With Piers
Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Paloma Furlan
Large wood increases the morphological and hydraulic complexity of rivers, yet it may block and modify the flood discharge capacity of hydraulic structures. To assess the related risk, blockage probability estimation for hydraulic structures such as reserv ...
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 ...
2021Experimental 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 ...
2021Plunge pool rehabilitation with prismatic concrete elements - case study and physical model of Ilarion dam in Greece
Romain Nathan Hippolyte Merlin Van Mol
The 130 m high Ilarion Dam is built on the Aliakmon River in northern Greece. The dam has two spillways with ski jumps at their ends and a plunge pool to cushion the impact of the jets. This pool has suered signicant scouring during several oods in recent ...
2021Plunging circular jets : Experimental characterization of dynamic pressures near the stagnation zone
Spillways are a requirement for dams' safety, mainly preventing dam over-topping in ood cases. A common spillway solution involves plunging jets which dissipate a considerable energy ow in the plunge pool. Dissipation has to occur in a controlled manner to ...
