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.

Analysis of scour characteristics in presence of aerated crossing jets
Author : S. Pagliara1, M. Palermo1, D. Roy1
The scour due to jets is a major topic for a hydraulic engineer. It has to be carefully analyzed in order to understand the mechanism and predict its geometry. The jets configuration has a deep influence on the scour features. In the present paper the analysis was conducted in presence of two symmetric crossing jets, varying the discharge, the air content, the tailwater level in the downstream stilling basin, the horizontal angle between the jets and the vertical distance of the jets crossing point from the water surface, for different vertical jets angle. It was proven that the presence of the air in the jets deeply affects the scour morphology. The scour depths were analyzed and some useful considerations on scour geometry were developed which are valid in the tested ranges of parameters.
