Modifying the downstream hydrograph with staged labyrinth weirs
Journal of Applied Water Engineering and Research, 2017Labyrinth and piano key weirs are hydraulically more efficient than linear weirs of common width. As the spillway discharge efficiency increases, the required reservoir detention volume reserved for flood routing reduces and the maximum base-flow operating reservoir pool elevation can subsequently be increased (additional water storage) without a ...

An Elegant Solution: The Lake Brazos Labyrinth Weir
Civil Engineering Magazine, 2009To fulfill the potential of the City of Waco’s Lake Brazos, a labyrinth weir replaced the gated spillway on the Brazos River. The labyrinth weir was constructed on a flowing river over the foundation of the existing dam without expanding the dam’s footprint or rerouting the river during construction — at nearly half the cost of earlier estimates.

Experimental modeling of circular labyrinth weirs with different weir heights and configurations
2022Due to their zigzag geometry in plain view, labyrinth weirs require less crest length compared to linear weirs in the dam body or in the channels where they are placed. In this study, the effect of the number of cycles (N) and weir heights (P) of the semi-circular labyrinth weirs on the flow efficiency was investigated.

Hydraulics of flow over labyrinth weirs [PDF]
, 1978 A review of the present state of knowledge related to the problems of labyrinth weirs and an experimental study of the flow in subcritical and supercritical conditions over labyrinth weirs having different slopes are presented in this thesis.A detailed examination of the following parameters affecting the flow and its variation along the weir has been ...
