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.

Determination of critical submergence depth at horizontal intakes under asymmetric flow conditions

ABSTRACT
The purpose of the present study is to investigate the hydraulic conditions of air-entraining vortices under asymmetrical flow conditions and derive a general expression to determine the critical submergence depth required for the formation of these vortices at horizontal intake pipes. A series of experiments were conducted in a model composed of a concrete reservoir and intake pipe which was mounted horizontally to the reservoir. Three pipes of different diameters were tested with adjustable plexiglass side walls to investigate the effect of side-wall clearances on the critical submergence depth. Based on the experimental results obtained from a wide range of side-wall clearances and discharges, empirical equations for the critical submergence depth were derived and compared with Gordon`s (1970) relationship.
