What is Rainfall Erosivity?

Rainfall Erosivity is the kinetic energy of a raindrop's impact and the rate of associated runoff. The R-factor is a multi-annual average index that measures rainfall's kinetic energy and intensity to describe the effect of rainfall on sheet and rill erosion.

What is Soil Erodibility?

Soil Erodibility (K) is the intrinsic susceptibility of soil to erosion by runoff and raindrop impact. Values of K range from the lowest erodibility, 0.02, to the highest, 0.69. All other factors being equal, the higher the K value, the greater the susceptibility of the soil to rill and sheet erosion by rainfall.
