AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Spillways often include a flip bucket as terminal energy dissipator, combined with a plunge pool. To prevent scour at the river bed for large jet fall heights additional measures are required, such as terminal chute widening or increase of the plunge pool ...
The flow after the rupture of a dam on an inclined plane of arbitrary slope, and the induced transport of non-cohesive sediment, is analysed using the shallow-water approximation. An asymptotic (analytical) solution is presented for the flow hydrodynamics, ...
The physical modeling tests for the rehabilitation of St-Marc Dam with a PKW are presented. A particular focus is put on the energy dissipation downstream from the PKW. The adopted solution is a leaned “ski-jump gutter” placed at the contact line between t ...
The safety of dams is very often endangered by the formation of scour near the foundation as a result of high-velocity jet impact. These jets issue from appurtenant structures such as spillways and may impact in the immediate vicinity of the dam toe. The p ...
Spillways often include a flib bucket as terminal energy dissipator, combined with a plunge pool. For large jet fall heights, the residual energy may provoke scour at the river bed. Additional measures are then required, such as chute widening, increase of ...
The International Commission on Large Dams' 79th Annual Meeting, to be held May 29-June 3 in Lucerne, Switzerland, brings together dam experts from throughout the world to exchange knowledge and experiences. Such information exchange is vital to ensure eff ...
The 115 m high Koman Dam is located in the northern part of Albania and is part of the Drin River hydroelectric cascade. The dam is equipped with two tunnel spillways with flip buckets at their downstream limits. Two large scour holes were created in the d ...
High-velocity plunging jets, issuing from ood release structures of dams, may result in scouring of the rocky riverbed and even endanger the foundation of the dams. Assessment of the scour extent is essential to ensure the safety of the dam and appurtenant ...
In this study the scour mechanism and the effect of some of the important parameters such as jet velocities, impinging jet distance from the upstream wall and tailwater depth on the longitudinal scour profile due to 3d simoultaneous wall and impinging jet ...
The Kühtai reservoir is planned as an addition to the existing Sellrain-Silz group of HPPs. Two natural hazards relevant in terms of potential impulse wave impact on the dam were identified: a snow avalanche near the dam axis and a possible landslide furth ...
