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.

Characteristics of air entrainment in hydraulic jumps
Author : MASAYUKI TAKAHASHI(1) & IWAO OHTSU (2)
mps is characterized by air entrainment and strong turbulence with the surface rollers. The characteristics
of air entrainment in jumps were investigated experimentally. The air entrainment region is classified into the advective
diffusion region and the breaking region. The air concentration in the advective diffusion region for a jump with a fully
developed inflow condition is larger than that for an undeveloped inflow condition for a given inflow Froude number,
whereas the air concentration ratio in the breaking region is independent of the inflow condition. For a given inflow
condition, the air concentration in both the advective diffusion and breaking regions increase with an increasing inflow
Froude number. The air entrainment mechanism in jumps is explained for both the advective diffusion and breaking
regions.Form Required :
