River-bed armouring as a granular segregation
River bed-load transport is a kind of dense granular flow, and such flows are known to segregate grains. While gravel-river beds typically have an “armoured” Abstract. River bed sediments typically fine downstream, where fining of median grain sizes are often described as exponential, except where fine gravel abruptly The gravel-sand transition and grain size gap in river bed
