Which term identifies erosion potential due to storm energy in rainfall data?

• A. R factor
• B. P factor
• C. C factor
• D. K factor

Answer: (A)

Rainfall erosivity, the R factor, captures the energy and intensity of rainstorms and how primed they are to cause erosion. In erosion models, the R factor represents the potential of storm energy to detach and transport soil particles—the more energetic and intense the rainfall, the higher the erosive potential. Other factors describe protecting or modifying erosion (P), cover and management (C), or soil properties (K), but they do not quantify the storm energy itself. So, the term identified by rainfall data that reflects erosion potential due to storm energy is rainfall erosivity—the R factor.
