Abstract
PKWs are considered an effective solution for dam designs which require either high specific discharge efficiency or low reservoir level. The influence of piano key weir geometry on discharge capacity was studied and for this purpose, twenty-seven physical models of two types(Aand D) of piano key weir and rectangular labyrinth weir(RLW) were constructed and tested, Dimensional analysis was carried out to find the influence of the geometric parameter on discharge capacity ratio .Prediction equations for discharge capacity ratio were found and compared with equatins for other investigators.The discharge capacity ratio of PKW was increased with increasing the value of (Wi/Wo). For PKW type A, the discharge capacity ratio was increased by (25%) with increasing the value of Wi/Wo from 0.5 to 2 , increasing the head over PKW, leds the discharge capacity ratio to be decreased.and variation in the height of PKW (P) doesn't affect the hydraulic performance of PKW . The discharge capacity ratio of PKW increased by(27%) with increasing the value of (L/W) from 3 t0 7. PKW type A was founded more efficient than the other types.
