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)...
