Sheet Erosion

sheet erosion

[′shēt i‚rō·zhən]
(geology)
Erosion of thin layers of surface materials by continuous sheets of running water. Also known as sheetflood erosion; sheetwash; surface wash; unconcentrated wash.

Sheet Erosion

 

(also surface wash or rainwash erosion), the removal of particles from the upper soil layer or the removal of the products of rock erosion by rain or melting snows that run down a slope in a solid sheet or in small streams. As a result, soils are eroded predominantly in the upper and middle parts of the slope and the eroded material is deposited at the foot of the slope. Sheet erosion is closely dependent on the steepness and length of the slope, the intensity of the precipitation, the rate at which the snow melts, the type of vegetative cover, and the use the territory is put to.

For example, a hot bum of stubble followed by long bare fallow maintained by multiple tillages will have a very high adverse impact on sheet erosion; thus, these practices are restricted to land with the greatest capability for sheet erosion.

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 [4].
It is necessary to evaluate the reliability of the DEM produced using a camera during the rainfall event to quantify the sheet erosion at the laboratory scale before field scale application.

The models used in this study considered gradual soil erosion (comprising sheet erosion and gully erosion).
The data shown in these figures indicate that the sum of sediment concentration due to rainfall and runon occurring separately is less than the sediment concentration achieved by these processes acting together, indicating a positive interaction at the low streampowers typical of these sheet erosion experiments, chosen to avoid filling or preferential flows.
Significant balance sheet erosion may lead to further rating pressure.
56] does not account for variations in the sediment concentrations observed on the plot well, and this is probably because sheet erosion, a process where detachment is dominated by raindrop impact, is a major contributor to erosion at the scale used in USLE experiments.
Balance Sheet Erosion: Current trends in liquidity metrics have been positive; a departure from those trends coupled with balance sheet erosion would likely result in negative pressure on the rating.
