Dam engineering is at present experiencing a robust revival of labyrinth orientated weirs. Labyrinth weirs, with a repetitive constructional personality and an elevated particular discharge ability, are a good technical-economical compromise. the idea that of Piano Key Weir (PKW), with alveoli constructed in overhangs from a discounted aid sector, permits the deploy of non-linear crests on the best of concrete dams. consequently it gets rid of the most situation of classical labyrinth weirs, and allows their use to rehabilitate a number of current dams.
Since the 1st implementation of piano key weirs via Electricité de France on Goulours dam (France) in 2006, a minimum of 8 PKWs were inbuilt France, Vietnam and Switzerland. Their operation over many years has already supplied the 1st prototype facts. different initiatives are lower than learn, building or making plans in assorted international locations. On one other hand, study courses are below growth everywhere in the world.
Following a primary version in 2011, Labyrinth and Piano Key Weirs II – PKW 2013 collects up to date contributions from individuals with numerous backgrounds, from engineers and researchers to lecturers. Summarizing the final advancements on labyrinth orientated weirs, the e-book constitutes the cutting-edge in learn and alertness of piano key weir recommendations, and may be useful to execs and scientists attracted to Dams Engineering.
