Abstract
The three-dimensional numerical computational fluid dynamics “CFD”
computer program "SSIIM" was used to predict the flow field downstream the
Kuffa Barrage. It solved the Reynolds-Averaged Navier–Stokes equations in three
dimensions to compute the water flow and used the finite-volume method as the
discretization scheme. The model was based on a three dimensional, nonorthogonal,
structured grid with a non-staggered variable placement. The
comparison between filed measurements and numerical results were considered to
make the correct decision in this model. The results showed that the maximum
velocities were inclined from the river center. The determination coefficients for
distribution of velocities ranged from 0.94 to 0.96.
