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.

ESTIMATE AGGREGATE SIZE OF ARMOR LAYER IN ALLUVIAL RIVERS USING IMAGE PROCESSING
Author : MILAD PAYESTEH , BABAK LASHKAR-ARA
The bed material size distribution in alluvial river is an important and challenging issue in the study of hydrological morphological and environmental behavior of rivers. utilization of new method such as image processing instead sieve approach for determination of bed river material size is more efficient .this study is used corrective watershed transform and image reconstruct algorithm for material size determination of armor layer of bed that implemented in MATLAB 2013.size distribution curve of maximum length of material of both algorithm is showed RMSE factor 6.43 for watershed transform and 3.04 for image reconstruct algorithm. models efficiency of material size determination in image reconstruct algorithm is 96.3 percent and in watershed transform this factor is 90 percent, that shows image reconstruct algorithm is more effective than watershed transform .
