| Abstract |
| This study had been performed to identity the application of SMS(Surface Water Modelling System) RMA-2 model to analysis of flow characteristics in curved channels. It is based on 2-D finite element method. A RMA-2 model which can analyze the flow and bed topography characteristics of a single bend and continuous one was suggested using the equations of mass, momentum, the vertical distribution of secondary flow. The calculated flow and bed topography characteristic values were compared with the experimental data in a single curved channel, and the predicted path of maximum streamwise velocity in continuous curved channels. It was shown that there is a reasonably good agreement between the numerical model and the hydraulic model for the most of computations. There were, however, some differences between the numerical simulation results and hydraulic experiment results for the water level in the channel basin because of relative distance for curved channel. |
