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.

3d numerical modeling of flow field and sediment transport in laboratory reservoir flushing process
Author : A. Khosronejad, C.D. Rennie , and S. Moghimi
For the computation of flow field and bed evolution in a water reservoir during the flushing process a fully three-dimensional curvilinear and non-orthogonal model, using a finite volume method to solve the Reynolds Averaged Navier-Stockes (RANS) equations, has been developed and combined with a three dimensional sediment transport model. The k - e turbulence model is used to calculate the eddy viscousity. The sediment transport model is based on the sediment concentrtion convection-diffusion equation, and the sediment continuity equation for calculating the bed level change in the reservoir flushing process. The hydrodynamic section of the model was verified using experimental data and the sediment concentration calculations compare well with the experimental results. Also, a physical model study was carried out to verify the results of bed evolution at the upstream of a sluice gate. Good agreement is found between bed evolution in the numerical and physical models.
