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.

Experimental Study on Scour Hole around Submerged Vanes at 180 Degree Flume Bend
Author : Alireza Masjedi
The submerged vanes are for river bend bank protection in alluvial channels. With proper distance, an array of vanes can significantly reduce the secondary current in a bend flow which is known being responsible for the erosion at the concave bank in a river bend. Investigation on scour and determination of hole of scoring are among the most important issues in submerged vane designation with model submerged-vanes was measured in a laboratory flume with 180 degree bend under clear-water. Experiments were conducted for different distances (d\H) and height (H\Y) various Froude number. In this study, the volume of the scour hole around the submerged-vane plates was studied. The results of the model study indicated that the maximum volume of scour is highly dependent on the experimental duration. It was observed that, suitable control at scour hole associated with d\H=15 and H\Y=0.3 submerged vane. With increasing Froude number the maximum scour hole increases.
