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.

Flow characteristics of two exemplar fishpass designs
Author : Stephen E. Coleman, Simon Croft, Mike Heiler, Jacques Boubée, Ambuj Dwivedi
Hydraulic modelling of selected fishpass designs facilitating upstream and downstream passage for small (50-100 mm long) migratory fish species was undertaken at The University of Auckland. The investigated designs included: a) a perturbation-boulder channel of arranged boulder roughness elements that are emergent for low flows, and b) a vertical-slot channel. The testing results presented in this paper include: the hydraulic roughness for the perturbation-boulder channel of large isolated roughness elements, and the discharge function for the vertical-slot fish pass.
