Description :
This paper reviews the various effects of rock fragments on soil erosion by water. Since these effects are scale dependent, they are investigated at three different nested spatial scales: the micro-, the meso- and the macroplot. For each scale the corresponding process mechanism are discussed. Particular attention is paid to the effects of rock fragment cover on the intensity of soil erosion processes. The scatter of the data indicates that a given rock fragment cover can have different efficiencies in reducing interrill and rill sediment yield depending on the varying intensities of the hydrological and erosion subprocesses.
