Abstract
Most gravel-bed rivers show the longitudinal sorting on riverbed materials. This phenomenon is due to combination of the selective sorting and the abrasion in bed material transport processes. We developed the stochastic model of bed-load transport with gravel abrasion processes. Applying this model to some ideal rivers which have different concavities in their longitudinal profiles and different geologies in their watersheds, we examined that the longitudinal sorting of riverbed materials was dependent not only on their selective transport according to the hydraulics, but also on their abrasion processes characterized by their watershed geology and lithology.
