Labyrinth and Piano Key Weirs III - PKW 2017

Since the first implementation by Electricité de France on Goulours dam (France) in 2006, the Piano Key Weir has become a more and more applied solution to increase the discharge capacity of existing spillways. In parallel, several new large dams’ projects have been built with such a flood control structure, usually in combination with gates. Today, more than 25 Piano Key Weirs are in operation or under construction all over the world.
Besides, more than 15 years of research and development have enabled detailed investigations of the hydraulic and structural behaviour of the Piano Key Weir complex structure and have provided more and more accurate design equations.
Following the books of proceedings of two first workshops held in Liege (Belgium – 2011) and Paris (France – 2013), this book gathered all the contributions presented by people with varied background, from researchers to practitioners, during the 3rd international workshop on Labyrinth and Piano Key weirs, organized in Qui Nhon, Vietnam. These papers, reviewed and accepted by an International Scientific Committee, summarize the current knowledge on Piano Key Weir, from a theoretical to a practical point of view, and present most of the main projects in operation or under construction.
Labyrinth and Piano Key Weirs III is thus a reference for students, practitioners and researchers interested in Dams Engineering.
