Analysis of various parameters affecting weir design and fabrication of Weirs: An Overview

open access: yesMATEC 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.
