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.

Frequency analysis of the river profile with streambed structures
Author : HUAIXIANG LIU(1), ZHAOYIN WANG(2) & YONGJUN LU(3)
ABSTRACT
As a prevalent phenomenon, there are many streambed structures in rivers. The distribution of them was obviously in
certain orders. This paper carried out numerical analysis and field work in natural rivers, to study the law of streambed
structuresí» distribution. The results indicated that: A river profile with streambed structures can be considered as an
overlay of two parts: an average longitudinal streambed line which reflect the total slope-trend; and a wave-shape line
vibrating along this average streambed line which reflect the effect of streambed structures. The two parts were then
distinctively separated by the frequency analysis. Then the distribution of streambed structures can be calculated and
analyzed more scientifically.
