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.
