(from ICOLD bulletin)
Van_Phong PKW (Vietnam)
This is the Chapter 6, concerning the PKW, in the next ICOLD bulletin (publication in 2016-2017)
‘TECHNICAL ADVANCEMENTS IN SPILLWAY DESIGN’
‘Progress and Innovations from 1985 to 2015’
…The recently developed Piano Key weir (PKW) spillway, which is an innovative structure that can convey very high specific discharges, is a variation of the traditional labyrinth weirs, firstly devised to circumvent some drawbacks of the latter (Barcouda et al., 2006). Using a rectangular layout and ramped floors which create overhanging or cantilevered apexes, the PKW is structurally simple and efficient, can be placed on existing or new gravity dam crest sections and multiplies significantly the discharge capacity compared to a standard weir of similar width (Ouamane and Lempérière, 2003)...
