Experimental study of discharge Coefficient of Piano Key Side Weir in 45-Degree Sector of a curved channel [PDF]
مهندسی منابع آب, 2020 A new type of Long-crested weirs is Piano Key weir that allows the reservoir to run at a higher level. The use of a Piano Key weir as side weir allows for more drainage, due to the geometric shape of the channel and the impact of centrifugal force on the

Analysis of various parameters affecting weir design and fabrication of Weirs: An Overview
MATEC Web of Conferences, 2018 Several geometric parameters influence weir discharge and it is explained in our present study. The PK weir is more efficient than rectangular labyrinth weir due to reduction in entrance losses of PK weir inlet key geometry.

Experimental Study of Hydraulic Flow of Circular Piano-Key Inlet in Shaft Spillways [PDF]
Journal of Rehabilitation in Civil Engineering, 2019 One of the most important conflicts that shaft spillways have to deal with is vortex formation. This phenomenon leads to some unfavorable effects such as vibration in the body of structures, air entrainment and reduced overflow capacity of the spillway ...
