Abstract

Thirty nine mobile and semi-mobile tracers were seeded in two selected reaches of the Plynlimon Experimental Catchments, to directly measure the abrasion of individual test clasts in the natural channel environment. Significant weight losses (~0.5g) sustained by tracers above the bed load trap, tracers fixed directly to bedrock, and tracers tethered confirmed the potential importance of over-passing bed load as an abrasion process. Weight losses sustained by tracers below the bed load trap (~0.05g) also indicated the potential of "sandblasting' as an additional "abrasion in place' process. -from Authors
