Abstract
Most of river engineering problems are complicated and need to be analyzed by three dimensional models of flow and sediment transport. Considering the fact that computers and numerical methods with great ability of flow and sediment transport simulation are developing quickly, using numerical modeling by engineers is inevitable. Nevertheless, before application, numerical models need to be verified in a wide range of engineering problems and their assumption should be clarified. This paper aims to investigate application of three dimensional numerical models in some complicated river engineering problems. To reach goals of this research, SSIIM2.0, which is a capable model of 3D flow and sediment transport, has been selected. This model was deployed for some intricate river engineering problems and its results were compared with some available experimental and field data. Results of this paper show applicability and accuracy of 3D numerical models in a wide range of river engineering problem.
