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.

Sensitivity Analysis of Flow Field Simulation in the Iffezheim Reservoir in Germany with the 3D SSIIM Model
Author : Qing Zhang, Gudrun Hillebrand, Irina Klassen, Stefan Vollmer, Nils Reidar B. Olsen, Hans Moser and Reinhard Hinkelmann
The results of modeling in river engineering are an elementary prerequisite for river management, especially sediment transport, and are consequently of fundamental importance. Therefore, t he aim of this paper is to analyze the flow field in the Iffezheim reservoir and to investigate the sensitivity of hydraulic and numerical parameters (e.g. time step, number of iterations, roughness and grid resolutions) on the results. This study will be the basis for a follow-up study on sediment transport in the Iffezheim reservoir. The simulations with the 3D SSIIM model are based on real-case data and the numerical results are compared with measurements in the range of available data. We have obtained an optimal time step and number of iterations concerning stability and CPU time, the grid resolution is discussed as well.
