Background and Objective

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 two first editions held in Europe (Liège, Belgium in 2011 and Paris, France in 2013), the third international workshop on Labyrinth and PKW moves to Asia, and in particular to Vietnam, where several large PKW projects are in operation or under construction.

As for the two previous editions, the workshop aims at bringing together people with varied background (engineers, researchers,...) to state and summarize the current knowledge on these non conventional hydraulic structures. Special emphasis will be put on planned and existing projects, with also first data from real structures operation.

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.
