Apr 17, 1998An alternative is to divide the sediment into only two size fractions, sand (grain size D s2 mm) and gravel (D g2 mm). Such a two-fraction approach is practical because a two-part bed composition may be measured more readily than the complete size distribution . This approach also allows sand and gravel to move at different rates.
