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.

Assessment of some bed load formulas based on sediment sampling
Author : MOHSEN TAHMASEBI NASAB(1), MOHAMMAD HOSEIN OMID(2) & JAVAD FARHOUDI(3)
ABSTRACT
Various researchers have assessed the applicability of existing sediment transport equations against collected sediment
data from natural rivers in addition to laboratory experiments. From all these studies, it can be concluded that existing
equations to predict bed load transport rate only can provide a guide, and further investigations are needed in order to be
able to predict bed load transport rate with adequate accuracy. This paper aims to assess the performance of the commonly
used bed load transport equations in estimating the sediment transport capacity of the Ghezel-Ozan River, which is one of
the most important rivers in Iran due to its high sediment load. The results suggest that the equations proposed by Julien,
Van Rijn, and Engelund and Fredsøe may reasonably predict bed load transport rates in the range of measured data.
