A labyrinth weir is a linear weir folded in a plan view to increase its crest length, resulting in the increase of flow rate for a given channel width and an upstream flow depth compared to traditional linear weirs. These weirs are also well suited for spillway rehabilitation in passing probable maximum flood with freeboard limitations where dam safety is of prime concern. The outflow process over labyrinth weirs has been studied experimentally, and the discharge coefficient equations have been developed based on statistical data analysis. In the present study, a simple discharge coefficient equation has been proposed using nonlinear regression analysis employing a sizable amount of data from the literature. This equation demonstrates applicability and accuracy when tested against field data.
