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.

How to Calculate Rainfall Erosivity Factor?

Rainfall Erosivity Factor calculator uses Rainfall Erosivity Factor = Soil Loss Per Unit Area in Unit Time/(Soil Erodibility Factor*Slope Length Factor*Slope-Steepness Factor*Cover Management Factor*Support Practice Factor) to calculate the Rainfall Erosivity Factor, The Rainfall Erosivity Factor formula is defined as a measure of the erosive force and intensity of rain that is used to describe the potential for soil to be washed off from disturbed, de-vegetated areas and move into surface waters during storms. Rainfall Erosivity Factor is denoted by R symbol.

How to calculate Rainfall Erosivity Factor using this online calculator? To use this online calculator for Rainfall Erosivity Factor, enter Soil Loss Per Unit Area in Unit Time (A), Soil Erodibility Factor (K), Slope Length Factor (L), Slope-Steepness Factor (S), Cover Management Factor (C) & Support Practice Factor (P) and hit the calculate button.
