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.

Free-surface and seepage bubbly flows on a gabion stepped spillway weir:experimental observations
Author : GANGFU ZHANG(1), & HUBERT CHANSON(2)
pillways are presented as a viable option for low to medium head designs. The material contributes to
stability, low cost, flexibility, porosity and noise reduction. The steps also enhance energy dissipation, and reduce the
requirement of a stilling basin. This paper constitutes a systematic study of the free-surface and seepage bubbly flows
using a combination of phase-detection probe and high-speed video camera. The two-phase flow properties and
turbulence characteristics in the free-surface flow were documented. The bubbly motion through the gabion material was
analysed. The results demonstrated evidence of strong air-water mixing between the free-surface and seepage flows,
and highlighted a modified cavity flow pattern as a result.Form Required :
