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.

Analysis of the role of turbulent structure in bedforms formation in a rectilinear flume
Author : Donatella Termini, Vincenzo Sammartano
The paper describes some peculiar results of experimental work carried out in a rectilinear flume in order to analyze the interactions between the turbulent bursting events of the flow and the bed deformation. The attention is focused on sweep and ejection events which contribute positively to Reynolds stress. The data analysis essentially confirms the existence of a strong relationship between the evolution of the turbulent events and the bed forms development. In particular, the obtained results highlight the formation of sequences of “horizontal bursts” whose evolution length compares well with the wavelength of the alternate bars found on the bed.
