Since the 1st implementation by way of Electricité de France at the Goulours dam (France) in 2006, the Piano Key Weir has develop into a increasingly more utilized option to elevate the release means of current spillways. In parallel, a number of new huge dam tasks were outfitted with this kind of flood keep watch over constitution, frequently together with gates. this day, greater than 25 Piano Key Weirs are in operation or less than development world wide. greater than 15 years of study and improvement have enabled designated investigations of the hydraulic and structural behaviour of the Piano Key Weir complicated constitution and feature supplied an increasing number of exact layout equations. Following the complaints of the 1st workshops held in Liege (Belgium – 2011) and Paris (France – 2013), Labyrinth and Piano Key Weirs III collects the contributions provided via individuals with diverse historical past, from researchers to practitioners, on the third foreign Workshop on Labyrinth and Piano Key Weirs - PKW 2017 (22-24 February 2017, Qui Nhon, Vietnam). The papers, reviewed and authorised via a global medical Committee, summarize the present cutting-edge on Piano Key Weirs from a theoretical to a realistic perspective, and current lots of the major initiatives in operation or below building.

Labyrinth and Piano Key Weirs III is hence a reference for college students, practitioners and researchers drawn to Dams Engineering.
