1-D numerical simulation of unsteady flow and non-uniform sediment transport at the Sanmenxia reservoir in the Yellow River

Flow in the Yellow River carries sediment in high concentration,and most of sediment transport occurs during the summer time.As the result the calculation of unsteady sediment transport is one of the most important tasks in the Yellow River.This paper presents the unsteady sediment concentration formula accounted for realistically in a model that has predictive power.Applications of the model to Sanmenxia resemvir are shown and compared with field measurement whenever possible.
