River engineers use computer models to predict sediment transport rates when field data is lacking. Two models were compared in this study: one based on the Parker equation and the other on the Meyer-Peter and Müller formula for graded sediments. The Meyer-Peter and Müller-based model was more accurate in predicting sediment transport rates, while the Parker-based model performed better in predicting grain sizes. This study highlights the current limitations of sediment transport models and areas that need further research.
