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.

Influence of one-line vegetation on the edge of floodplain on velocity and boundary shear stress distributions in compound channel
Author : B. Terrier1 , Y. Peltier1 , K. Shiono2, A. Paquier1 and N. Rivière3
The role of riparian vegetation on the ecology of river systems is paramount. However, the impact of vegetation bordering the main channel on the flow field in a compound channel is little known. In this study, experiments were therefore conducted in a 1.2 m wide and 8 m long compound channel with 9 mm diameter wooden rods placed along the edge of floodplain to understand its impact on flow field. Longitudinal velocity was measured with a micro-propeller and a Pitot tube and boundary shear stress was measured with a Preston tube. Comparison between the cases with and without rods shows that the impact of rods increases significantly with relative depth, as drag force also increases. The modified Shiono and Knight Method presented in Rameshwaran and Shiono (2007) is applied to the experimental flow cases.
