The Piano Key Weir (PKW) is a weir of particular geometry, associating to a labyrinth shape the use of overhangs to reduce the basis length. The PKW can thus be directly placed on a dam crest. Together with its important discharge capacity for low heads (several times the one of a Creager weir), this geometric feature makes the PKW an interesting solution for dams rehabilitation as well as new constructions.
Following a first edition in Liege (Belgium) in 2011, this 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 non conventional hydraulic structures.
High level papers selected by the International Scientific Committee and presented during the workshop will be published in a hard cover book before the conference.
The workshop environment is willing to be friendly, co-operative and non-competitive.
