Effect of Flow Splitters on Energy Loss in C-Type Piano Key Weirs
Journal of Engineering and Sustainable DevelopmentPiano key weirs (PKWs) are a new type of labyrinth weirs. They have a longer crest length within a limited width and, unlike linear weirs, ultimately have a higher discharge coefficient. The higher energy loss in PKWs can reduce scour.

Finding Potential of Increase in Water Level at Piano Key Weirs using Physical models [PDF]
مهندسی منابع آب, 2017 The Parapet Walls were installed on the top of PKW crest. There slopes were investigated with the 3.0 co-flow angles 3. 5.5 and 8 Degrees (positive slops) and counter-flow slopes (negative slopes). The Parapet Wall heights were 2.5, 4.5 and 6.5 cm on the

Prediction of the discharge capacity of piano key weirs using artificial neural networks
Journal of HydroinformaticsThe discharge capacity of the piano key weir (PKW) is an important flow feature which ultimately decides the design of PKWs. In the present research work, the different architecture of artificial neural networks (ANNs) was employed to predict the ...

Piano Key Weir Head Discharge Relationships
, 2011 A piano key (PK) weir is a type of nonlinear (labyrinth-type) weir developed specifically for free-surface flow control structures with relatively small spillway footprints. Currently, no generally accepted standard PK weir design procedure is available.
