Three-dimensional numerical simulation of the Yellow River flow in Shapotou river bends

In order to grasp the water forms and sedimentation of the Yellow River flow in Shapotou river bends and to exert reservoir benefit, 3-D velocity, water depth and river-bed level of some classical cross-sections were measured and analyzed using “River Cat” system. In addition, the velocity of river bends were simulated using k - ε turbulent model and Finite Volume Method. Good consistent between numerical and measured results indicates that the model can reflect the velocity distribution and the circulation phenomenon of river bends.
