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.

Development of an integrated sediment transport model and its application to the danube river
Author : M. Tritthart, B. Schober, M. Liedermann, H. Habersack
This paper presents the development, validation and application of an integrated numerical sediment transport and morphology model which relies on external 2-D or 3-D hydrodynamic codes to provide the flow field and bed shear stress patterns driving sediment transport processes. The model solves a convectiondiffusion equation to account for suspended load; in addition, four different empirical transport formulae are implemented for the computation of bedload. All equations
are evaluated for an unlimited number of sediment size fractions, allowing for the investigation of sorting processes. The numerical code was validated using measurements from several laboratory experiments. Good agreement with the computational results was found, proving the general validity of the sediment transport model. After successful validation, the model was applied to a 4 kilometer reach of the Austrian Danube East of Vienna. In the scope of this project, sediment transport and morphodynamics were computed using the numerical model presented.
