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.

Surficial sediment size distribution through the use of digital imaging and autocorrelation analysis
Author : F.K. Tedla, J.A. Tuhtan, S. Hartmann, S.Wieprecht , M. Schneider
Information on grain size distribution has many applications in the field of fluvial engineering, such as sediment transport and deposition, and fluvial habitat modeling. This study aims at finding a sampling and analysis technique that achieves a satisfactory characterization of grain size while simultaneously reducing the time spent in both the field and the laboratory. During this study a new method of size distribution of river bed materials through digital imaging and autocorrelation analysis has been used. 75 % of the samples analyzed show strong correlation to the sieve analysis results. Overall average error of around 10 % is observed. Moreover, the method proves to be cheaper and faster than the traditional methods by more than 100 %.
