The calculation of flow and sediment transport is one of the mostimportant tasks in river engineering. The task is particularly difficult because a num-ber of complex physical phenomena should be accounted for more realistically in amodel with a predictive power. Three-dimensional calculations of river flow and sus-pended sediment transport are performed in this paper with application in the ThreeGorges Reservoir in the Yangtze River. A period of 76 years after the dam is built issimulated and the results are compared with laboratory measurements obtained byTsinghua University whereby the model is verified and calibrated. Generally speak-ing, the calculated results agree well with the experiments, demonstrating that thepresent model can be used for flow and sediment transport prediction in rivers.

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.
