摘要：
In this study the precision of ten sediment transport formulas is evaluated by comparing their results with existing data which cover flow regimes that occur in Tejo (Tagus) and Mondego rivers in Portugal. Several selection criteria were applied, allowing us to conclude that the formulas of Karim and Kennedy 90 and Karim and Kennedy 81, produce the best results, leading to small errors and covering a high percentage of observed situations, both when applied to the entire data set or when applied to more homogeneous sub-sets of the same data.
