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.

Coherent eddy structure in meandering compound open-channel flows
Author : Michio Sanjou, Iehisa Nezu and Hoang Quang
It is very important to reveal the coherent structure in meandering compound open-channel flows for predicting the transport properties of suspended sediments in rivers in flood. However, flow-visualization techniques such as PIV and PTV, have not sufficiently been applied to such flows in previous studies, and thus, there is almost no detailed information on coherent turbulence in meandering compound open-channel flows. Therefore, in this study, we conducted some PIV measurements with a high-speed CMOS camera. The time-averaged velocity properties and coherent turbulence structure were investigated and considered on the basis of the present measured data.
