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.
Even though flow in natural rivers and channels is generally unsteady, only a few studies on turbulent structures in unsteady open-channel flows have been carried out. In hydraulic engineering problems, unsteady flow is often approximated with concepts of ...
The worst enemy of sustainable use of reservoirs is sedimentation. Often the main silting process is the result of settling down of suspended sediments. In shallow reservoirs the flow pattern and the sediment deposition processes are strongly influenced by ...
Shallow reservoirs are threatened by fast filling up with sediments, even if the entering sediments are only suspended loads. The sedimentation process is strongly influenced by the geometry of such shallow reservoirs. In the framework of a research projec ...

Reservoir sedimentation is worldwide a significant long term problem and requires in view of the current mitigation measures an alternative and more sustainable solution. This challenge motivated the present study with the purpose to develop an alternative ...
Reservoir sedimentation and the resulting storage losses impact reliability, efficiency, safety and thus the sustainability of the hydropower schemes. Beside traditional storage hydropower plants, also pumped-storage facilities are affected. Flexible turbi ...
Sedimentation close to dams in large and deep reservoirs is mainly related to sediment transport by turbidity currents. The state of the art regarding the management of turbidity currents is presented here, and illustrated with two case studies. Possible s ...

Sediment-water fluxes are influenced by both hydrodynamics and sediment biogeochemical processes. However, fluxes at the sediment-water interface (SWI) are almost always analyzed from either a water-or sediment-side perspective. This study expands on previ ...
In flood protection engineering, side weirs or overflow dams are used to divert water in a controlled way into flood plains as soon as the discharge capacity of the main-channel is reached. Because of the lateral loss of water, the sediment transport capac ...
