| This study was purposed to validate the capability of the TELEMAC model for simulating bended flow of natural rivers. A laboratory hydrodynamic test was done with an open channel with 30o, 60o, and 90o bended sections, and the measured hydrodynamic data were compared with the simulation data of the TELEMAC model. The measured and simulation data (i.e. flow velocity and water depth) in the straight sections of the channel were similar to each other, without variation along the cross-section, because the straight sections were not under the centrifugal force. However, in the bended sections, under the centrifugal force, the measured and simulation data showed that water depth increased but flow velocity decreased from the inner to the outer bend. For both of the straight and bended sections, the errors between the measured and simulation data were less than 7 % error. Therefore, we concluded that the TELEMAC model can properly simulate hydrodynamics in the bended channel, and it can be a good hydrodynamic simulation program for planning, designing, and early warning of bended natural rivers. |
