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.
Numerous stepped spillways were built to date, namely on RCC gravity dams or on valley flanks besides embankment or rockfill dams, while some others are currently under design or construction. In some cases, slope changes may be required on stepped chutes, ...
Roller compacted concrete gravity dams are built since several decades. In combination with such dams, stepped spillways are very often used as efficient flood release structures. More recently stepped spillways are also excavated into rock along the abutm ...
Physical modeling represents probably the oldest design tool in hydraulic engineering together with analytical approaches. In free surface flows, the similitude based upon a Froude similarity allows for a correct representation of the dominant forces, name ...
To protect spillways against cavitation damage, adding a small air concentration to the flow close to the invert is efficient. Aerator performance on smooth chutes was therefore well studied in terms of air entrainment and downstream air concentration deve ...
In a time when governments are pursuing increasingly ambitious energy efficiency goals, building energy simulation at the urban scale, combined with the high availability of physical data, can help in performing this task. The purpose of this study is to d ...
Application of stepped spillways increases the energy dissipation rate along the spillway and may reduce the dimensions of the terminal energy dissipation structure. This pronounced energy dissipation makes stepped chutes attractive under various condition ...
This paper investigates the importance of the design parameters when looking at possible energy savings and comfort enhancement in a building using Phase Change Materials (PCMs). Computer based simulations are performed using a simulation software for mode ...
Stepped spillways are currently a standard design in hydraulic engineering. Whereas these spillways were hardly employed until the advent to the Roller-Compacted Concrete (RCC) Technology in the 1980s, they were of particular interest from the 1990s for sp ...
In the 19th Century, hydraulic engineering was typically addressed in two parallel approaches. On one hand, classical theoretical fluid mechanics with the use of analytical approaches to study various flow occurrences. Due to the difficulty and complexity ...
Haraz dam under construction is located along Tehran-Amol road, 20 km upstream of the Amol city. A tunnel has been designed to detour the traffic temporarily around the dam site to avoid any closure of the main road. This tunnel will be integrated in the m ...
