Abstract :
[en] Dam engineering is currently experiencing a strong revival of labyrinth oriented weirs. Labyrinth weirs, with a repetitive constructional character and an increased specific discharge capacity, are a very good technico-economical compromise. The concept of Piano Key Weir (PKW), with alveoli developed in overhangs from a reduced support area, enables to install non-linear crests at the top of concrete dams. It eliminates thus the main drawback of classical labyrinth weirs and enables their use to rehabilitate numerous existing dams. Since the first implementation of PKW by Electricité de France on Goulours dam (France) in 2006, at least eight PKWs have been built in France, Vietnam and Switzerland. Their operation over a few years has already provided the first prototype data. Other projects are under study, construction or planning in varied countries. On another hand, research programs are under progress all over the world. Following a first edition in Liege (Belgium) in 2011, the 2nd international workshop on Labyrinth and PKW aims at bringing together people with varied background (engineers, researchers,...) to state and summarize the current knowledge on these still non-conventional hydraulic structures. The papers reviewed and accepted by an International Scientific Committee and presented during the workshop sessions are published in the present book which can be considered as an up-to-date Reference document.
