Déversoirs en labyrinthe et en touches de piano [PDF]
, 2011 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 (

Laboratory Study of the Hydraulic Performance of the A-Type Triangular Piano Key Weir [PDF]
Water (Switzerland), 2023 A piano key weir (PKW), a new type of weir aiming to increase the discharge capacity of an existing dam, was recently designed. Despite a large body of research in this field, only a few studies were conducted on A-type triangular piano key weirs (TPKW ...

Piano Key Weir is a cost-effective and hydraulically performant solution for spillways, considered as a Climate Change adaptation as well. In order to enhance the understanding of the hydraulic behavior of the A-type PKW and to investigate the effects of introducing a crest slope, an experimental study has been performed. This new configuration aims to
