Determination of Discharge Coefficient for both Semicircular and Triangular Labyrinth Weirs
Polytechnic Journal, 2021 A Labyrinth weir is a type of nonlinear weir folded in plan-view, with the ability to pass a large flow at low heads due to an increase in the effective length of the weir crest for a given channel width.

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.

Numerical Investigation of Geometric Parameters Effect of the Labyrinth Weir on the Discharge Coefficient [PDF]
Journal of Rehabilitation in Civil Engineering, 2018 Weirs, as overflow structures, are extensively applied for the measurement of flow, its diversion, and control in the open canals. Labyrinth weir as a result of more effective length than conventional weirs allows passing more discharge in narrow canals.
