Experimental Study of Discharge Coefficient of Symmetric and Asymmetric Rectangular Labyrinth Weirs
The discharge coefficient of labyrinth weirs increases with increasing the crest length in a certain width range. The present research was carried out in a laboratory flume with a length of 8 m, a width of 0.6 m, and a height of 0.6 m. The discharge coefficient of two-cycle symmetric and asymmetric rectangular labyrinth weirs was experimentally measured. The dimensional analysis by the Buckingh...

A labyrinth weir is a nonlinear weir folded in the plan-view which increases the crest length and the flow rate for a given channel width and an upstream flow depth. Nowadays, a labyrinth weir is an attractive alternative for those weirs that have a problem in passing the probable maximum flood. The three-dimensional flow pattern and unlimited geometric parameters provide a major challenge to t...
متن کاملAn Approach to Optimal Design of Trapezoidal Labyrinth Weirs
Trapezoidal labyrinth weirs offer significant flow magnification 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. There are many factors such as head to crest height ratio, angle of side walls, vertical aspect ratio, apex width and approach and con...
متن کاملFrom Labyrinth to Piano Key Weirs – A historical review
Free crest spillways are hydraulically efficient and safe in operation. Since their discharge capacity is directly proportional to the crest length several types have been developed with the purpose to increase the length of the latter. Among these types traditional labyrinth weir spillways have been studied and used for a long time. Their hydraulic performance and the effect of the involved ge...
متن کاملNumerical Investigation of Geometric Parameters Effect of the Labyrinth Weir on the Discharge Coefficient
Weirs, as overflow structures, are extensively used for the measurement of flow, its diversion and control in the open canals. Labyrinth weir due to more effective length than conventional weirs, allows passing more discharge in narrow canals. Determination the design criteria for the practical application of these weirs need more investigation. Weir angle and its position relative to the flow ...
