Abstract: | The calculation of flow and sediment transport is one of the most important tasks in river engineering. The task is particularly
difficult because a number of complex physical phenomena should be accounted for more realistically in a model with a predictive
power. Three-dimensional calculations of river flow and suspended sediment transport are performed in this paper with application
in the Three Gorges Reservoir in the Yangtze River. A period of 76 years after the dam is built is simulated and the results
are compared with laboratory measurements obtained by Tsinghua University whereby the model is verified and calibrated. Generally
speaking, the calculated results agree well with the experiments, demonstrating that the present model can be used for flow
and sediment transport prediction in rivers.
