Influence of Inlet- and Outlet-Key Configurations on the Discharge Coefficient and Crest Discharge Distribution of Type-A Piano Key Weirs
Piano key weirs (PKWs) increase the effective crest length and provide high discharge capacity within limited spillway widths; however, their hydraulic efficiency depends on key geometry. Addressing the limited understanding of key-curvature effects, this study systematically investigates the influence of inlet- and ou...
