چکیده انگلیسی

Computational power and development of numerical models are new windows for simulation about flow and sediment transmission. The aim of this article is related to Numerical modeling of three-dimensional flow and sediment at the narrowing location of bridge. We selected the SSIM2 model because this model has high ability for numerical simulation. We used this model in the erodible and rigid bed. We compare the results with experimental data. Comparison shows model with high ability for simulation about velocity and level of water but when the value of perturbation is high to have the high error for simulation. The numerical model is used for scour depth and bed variations. This model predicts the bed variation and scour depth and it shows the maximum of scour depth but the depth of scour hole is less about fifteen percent than experimental results. Based on all the results, this method suggests a good tool about river engineering problems.
