Modification of the Ackers-White method for the calculation of sediment transport by size fractions has led to a procedure which not only permits such calculations, but also increases the accuracy of the total sediment transport for broadly graded sediments. However, it has also brought to light some problems associated with the original procedure. The results are currently being incorporated into HEC-6.
