| Abstract: | The secondary flow in river bends has significant effects on flow velocity and sediment concentration distribution in the transverse direction. By simulating a vertical 2-D secondary bend flow, the secondary flow effects were taken into account and the simulation was coupled with a planar 2-D depth-averaged model. The computational results showed that this method was widely applicable and the additional needed calculation work was limited. |

| Keywords: | bend secondary flow 2-D model flow velocity transverse distribution |
