Calibration of discharge co-efficient for labyrinth weir

Abstract

Trapezoidal labyrinth weir offer significant flow for the available width of approach channel and that of the
downstream chute. These types of weirs may find great utility and hence will have to be designed and provided for river
linking projects. Total length of labyrinth weir is typically three to five times the spillway width of straight overflow weir.
In this paper, mathematical model for double and triple cycle labyrinth weir are proposed and analysis carried out for
co-efficient of discharge and various parameters for double and triple cycle labyrinth weir. The experimental results are
in good agreement with the results obtained by Tulli’s and other investigations.
