Piano Key Weir Hydraulics and Labyrinth Weir Comparison

Journal of Irrigation and Drainage Engineering - ASCE, 2013
AbstractA piano key (PK) weir is a type of nonlinear (labyrinth-type) control structure with a relatively small spillway footprint.

Staged Labyrinth Weir Hydraulics

Journal of Irrigation and Drainage Engineering - ASCE, 2013
AbstractLabyrinth weirs with multiple crest elevations (i.e., staged labyrinth weirs) can be used in spillway design to confine base flows to a section of the crest and/or satisfy discharge hydrogr...

Performance and Design of Labyrinth Weirs

Journal of the Hydraulics Division, 1970
The purpose of the labyrinth weir is to increase the discharge per unit width of channel beyond that usually obtained from a conventional weir under identical head conditions. This is achieved by compressing a large length of crest in concertina form into the space available on site.

Discharge coefficient of a rectangular labyrinth weir

Proceedings of the Institution of Civil Engineers - Water Management, 2013
A rectangular labyrinth weir has a very good flood release capacity as well as strong economical and structural advantages. In this study, combined analytical and experimental investigations were undertaken for a rectangular labyrinth weir. The analytical model is based on the synthesis of general weir equations and spatially varied flow dynamic ...

Case study of a labyrinth weir spillway

Canadian Journal of Civil Engineering, 1990
A labyrinth weir is an effective and economical means of providing increased spillway capacity under some restricted operating conditions. This type of weir is particularly suited to reservoir sites where a low head to high discharge relation is required, the topography restricts the spillway width, and a self-operating structure is highly desirable ...

Labyrinth Weirs with Angled Approach Flow

Journal of Hydraulic Engineering, 2018
AbstractCurrent design methods and research have primarily investigated the hydraulic characteristics of labyrinth weirs when the approach flow is perpendicular to the weir axis, a condition consis...
