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.

Entrainment and suspension of fine sediments in open channel flows
Author : YAN LIU(1), HONGWEI FANG(2) & JING BAI(3)
Suspended sediment transport was considered one of the most important issues in river management. In recent years,
researchers started to use large eddy simulation as a powerful tool to study fine sediments entrainment and their
transport in turbulent flows (Zedler and Street, 2001; Chou and Fringer, 2008; Nabi et al., 2013; Bai et al., 2013).
However, it is still not well known how suspended sediments are impacted by channel walls and near-bed turbulent
structures. The current study aims at providing better insight into the interaction between fine sediments and turbulent
flow structures caused by channel walls and rough beds. Three key elements in fine sediments transport are investigated
in this study: (1) sediment pick-up on rough beds, (2) channel aspect ratios and (3) long-distance transport feathers.
