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.

Non-Uniform Open Channel Flows Study Using Three-Dimensional Turbulence Measurements
We conducted an experimental study to investigate the three-dimensional (3D) turbulence characteristics, including 3D turbulence intensities and Reynolds stresses, of different non-uniform open channel flows over the smooth bed. First, the methods used to process the experimental data were outlined and reviewed; then, the experimental instrument and conditions were discussed; finally, the analyses on various experimental data were performed. The analyses of our data set showed that the measured non-uniform flows present a slightly higher von Karman constant ? than the commonly proposed value, while the commonly used wake law integration constant B and wake parameter ? r presented similar characteristics as those in the literature. The findings from our measured data further contribute to the 3D flow turbulence characteristics study, which are useful for the non-uniform flows investigation that fewer studies had been focused on in comparison with the uniform flows study.
