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.

necessary to maintain the ecological continuity of rivers. Standard design is well documented in literature
for different kind of rivers and target fishes. When site constraints jeopardize the applicability of such standard shapes,
additional studies are required to verify that flow patterns are compatible with fish swimming capacities. Both physical and
numerical modeling can be used for these studies. Physical modeling catches all the complexity of turbulent 3D flow in the
fish pass basins but is usually expensive. Numerical modeling is cheaper and more versatile, but model parameters need
to be adjusted carefully to ensure proper results. In this paper, three numerical models are compared to scale model
results for two different case studies. This enables identification of advantages and weaknesses of each model.Form Required :
