is caused by the movement of water over the land surface.
Consistent with the characteristics of these soils, grassland productivity is diminished by sheet erosion
(87%), excessive moisture (62%) and soil acidity (37%), factors that act with different intensities.
Restoration of eroding areas vulnerable to erosion:installation of gully and sheet erosion
Finally, it was found that the rate of Light erosion was great in upper stream and decrease toward the outlet, while the heavy erosion appear in downstream, suggesting presence of a clear correlation between the stream order and degree of water erosion, whereas the sheet erosion
correlated with Initial orders, while Rill and Gully erosion correlated with major orders.
A generic framework was developed during the NSW MER program that considers the broad potential impact of a range of land-management actions on the individual land-degradation hazards comprising the LSC classification (sheet erosion
, structure decline, etc.).

and maize grain yield in semiarid conditions and granitic sandy soils of Zimbabwe," Applied and Environmental Soil Science, vol.
During the past twenty years, many researchers paid attention to the process of rill and sheet erosion
while some researchers have showed that rill and sheet erosion
on the plot is not an ideal indicator of the total amount of soil erosion .
Soils are also subject to rill, gully and sheet erosion
of varying degrees.
Moreover, studies reporting this method to monitor sheet erosion
, which predominates in drylands, are relatively few.
Nevertheless, these previous studies largely account for the declines in sheet erosion
. None of the above studies, however, have specifically investigated the potential continuing role of persistent gullies.
can often be observed as lighter-colored soils on knolls in rolling fields.
is considered to be a uniform removal of soil in thin layers from sloping land, resulting from sheet or overland flow.
