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.

Prediction of momentum and solute transfer in a vegetated compound channel
Author : Fatima Jahra, Yoshihisa Kawahara, Fumiaki Hasegawa and Takuya Yamamoto
This study aims at revealing the momentum and solute transfer mechanism in a vegetated compound channel. The laboratory experiments and three-dimensional numerical simulations have been carried out for turbulent flow with solute transport in the presence of emergent vegetation located on the floodplain. The numerical simulation employs a non-linear k-ε model with a vegetation model for turbulent flow field and an eddy diffusivity model for solute transport. Vegetation zone has been prepared on one side of the symmetric prismatic compound channel to identify mixing mechanism. The numerical results are compared against the experimental observations in terms of mean velocities, solute concentration and Reynolds shear stress components, showing a fairly good agreement between simulated and experimental results.
