Since the 1st implementation by means of Electricité de France at the Goulours dam (France) in 2006, the Piano Key Weir has develop into a a growing number of utilized approach to raise the release means of current spillways. In parallel, a number of new huge dam tasks were equipped with this type of flood keep watch over constitution, frequently together with gates. this present day, greater than 25 Piano Key Weirs are in operation or lower than building around the world. greater than 15 years of analysis and improvement have enabled certain investigations of the hydraulic and structural behaviour of the Piano Key Weir complicated constitution and feature supplied increasingly more actual layout equations. Following the lawsuits 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 diversified history, from researchers to practitioners, on the third overseas Workshop on Labyrinth and Piano Key Weirs - PKW 2017 (22-24 February 2017, Qui Nhon, Vietnam). The papers, reviewed and permitted by means of a world medical Committee, summarize the present cutting-edge on Piano Key Weirs from a theoretical to a realistic viewpoint, and current many of the major tasks in operation or lower than building.
Labyrinth and Piano Key Weirs III is hence a reference for college students, practitioners and researchers attracted to Dams Engineering.
