Hydraulic Advantage of Piano-key Weir Over Ogee Weir
View through CrossRef
The piano-key weir is a new encouraging hydraulic structure yet to become a widespread usage due to limited knowledge of the hydraulic performance. A laboratory investigation on the hydraulic efficiency of the piano-key weir was compared with that of an ogee weir. The experiment data confirmed that the piano-key weir discharged more than ogee weir for the same upstream head. However, the coefficient discharge of the piano-key weir is extremely low compared to the ogee weir.

Title: Hydraulic Advantage of Piano-key Weir Over Ogee Weir
Description:
The piano-key weir is a new encouraging hydraulic structure yet to become a widespread usage due to limited knowledge of the hydraulic performance.
A laboratory investigation on the hydraulic efficiency of the piano-key weir was compared with that of an ogee weir.
The experiment data confirmed that the piano-key weir discharged more than ogee weir for the same upstream head.
However, the coefficient discharge of the piano-key weir is extremely low compared to the ogee weir.

Abstract
Discharge over an ogee weir is related to the length of the weir, upstream total head above the weir crest and the discharge coefficient. The discharge coef...
