Soil Erosion: Processes, Prediction, Measurement, and Control
Half Month Period Dec. Smith, 1978). Erosivity also varies within the year. Figure
2.2 illustrates the average variation in erosivity over a year for four locations in
the United States. Much of the annual erosivity occurs during the winter and early
...

Soil Conservation and Management in Developing Countries: ...
It is possible that there could be an interaction effect between erosivity and
erodibility. In that case a measure of erosivity based on the ability of rain to cause
detachment might not be the same as a measure of erosivity based on the ability
to ...

Soil Erosion Research Methods
Therefore, the erosivity term should consist of both rainfall and overland flow or
runoff components (59, 65). Onstad and Foster (65) proposed a combined energy
term, W, computed as follows: W = 0.5EI3015Qq1/3 [33] where Q is storm runoff ...

Environmental Modelling: Finding Simplicity in Complexity
The data from this model were presented on a Gaussian 3.750 by 3.750 grid.
Changes in rainfall erosivity for the two models were computed for two time
intervals, 40 and 80 years. In the first case the values of erosivity from the 20—
year ...

The erosivity results calculated from the Hadley Center model analyses indicated
a general increase in rainfall erosivity over large parts of the eastern USA,
including most of New England and the Mid-Atlantic states as far south as
Georgia, ...

Interpreting Soil Test Results: What Do All the Numbers Mean?
4.3.3 Rainfall erosivity Rainfall erosivity in the Universal Soil Loss Equation is the
ability of the rain to cause erosion. Its derivation is described in Rosewell and
Turner (1992) and Rosewell (1993). Its basic units are MJ.mm/(ha.h.yr). The
actual ...

The equation states that A=RKLSCP (11.17) where A - estimated gross soil
erosion, t/(ha/year) R - rainfall erosivity factor, joules/(ha/year), (t-m/ha) (mm/h)

Upland Rice: A Global Perspective
Wischmeier and Smith (119) developed the Universal Soil Loss Equation (USLE)
to predict or evaluate soil losses caused by erosion: where A = annual soil loss (t/
acre), R = climatic erosivity (foot/t), K = soil erodibility, SL= topographical index ...
Phool Chand Gupta, J. C. O'Toole, 1986
Pluviological methods used in soil erosion research, and for making
measurements of rain erosivity, respectively, belong to the group of climatological
methods by which the erosivity of climatic erosion factors (mainly precipitation
and wind) ...
