IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Labyrinth weirs: developments until 1985
Author : WILLI H. HAGER(1), MICHAEL PFISTER(2) & BLAKE P. TULLIS(3)
ABSTRACT
The weir is a fundamental structure in hydraulic engineering, serving to retain a water body, to control a water level,
facilitate flow diversion, or to measure discharge. Under particular site conditions, the cross-sectional width at the weir
location is limited so that either higher overflow depths or a compressed weir expansion are set. A form of the latter
arrangement is the so-called labyrinth weir, which is composed of rectangular, trapezoidal or triangular plan shaped
weirs, so that the geometrical crest length is increased. Along with the recently developed Piano Key Weir, labyrinth
weirs represent economically and hydraulically sound alternative for increasing spillway discharge capacity. The present
paper describes their historical development, reviews the main advances until the 1980s, summarizes current design
guidelines, and presents the main individuals having participating in their development.
