In this paper the analysis of each process factors was derived as follow:
1. Rainfall Erosivity Factor (R)
The soil loss is closely related to rainfall partly through the detaching power of raindrop
striking the soil surface and partly through the contribution of rain to runoff (Morgan, 1994).

The most suitable expression of the erosivity of rainfall is an index based on kinetic energy of
the rain. There are different ways of analyzing the R factor. For instance,
