The significance of velocity exponents in identifying erosion-corrosion mechanisms [PDF]

open access: yes, 1993
The modes of erosion-corrosion are diverse and may vary from being ''erosion-dominated'', where erosion of metal is the dominant process, to ''corrosion-dominated'', where erosion of oxide scale is the dominant process.

Enrichment of organic carbon in sediment transport by interrill and rill erosion processes [PDF]

open access: yes, 2008
Erosion and loss of organic carbon (OC) result in degradation of the soil surface. Rill and interrill erosion processes on a silt loam soil were examined in laboratory rainfall and flume experiments.
