Abstract
The bed material size in alluvial channels reduces with distance. This size reduction is caused by the physical size attrition of particles, called abrasion, and by the differential transport of sizes, called sorting. A mathematical model is presented to simulate the bed material sorting in alluvial channels. Application of this model to hypothetical channels shows that the sorting coefficient depends on the channel slope, regime of flow, and total bed material transport. Also, it is shown that in channels formed by aggradation of material transported from upstream, strict equilibrium is not possible in the absence of abrasion.
