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.

Effect of Pipeline Orientation on Scour Mechanism in Unidirectional Steady Flow
Author : Mohd. Azlan Mohd Yusoff, Hazi Md. Azamathulla, Zorkeflee Abu Hasan, Nor Azazi Zakaria and Mohd Zulkifly Abdullah
The 3-dimensional flow velocity components at several different points, which are distributed equally across the channel width and the associated scour hole, are measured in order to investigate the flow components and scour mechanism around fully submerged pipeline across the channel. Three different pipeline orientations, which are 30, 60 and 90 from the side wall of the channel are installed at fully developed flow point in the main channel. A 3-dimensional down-looking acoustic Doppler velocimeter (ADV) is then used to measure the flow velocities at several points across and along the channel. The effect of the pipeline orientation, the flow characteristics, the horseshoe vortex effect and other associated factors is discussed in the paper.
