Qualified SWPPP Practitioner And Developer (QSP QSD) Practice Test

Which list contains all factors used in RUSLE?

R, K, LS, C, P R, P, S R, K, C K, LS, P

Correct Answer:

R, K, LS, C, P

Explanation:

In RUSLE, soil loss is predicted by multiplying five factors. The five factors are R (rainfall erosivity), K (soil erodibility), LS (slope length and slope steepness), C (cover-management), and P (support practices). The equation is A = R × K × LS × C × P, so the complete list must include all five. Any other option leaves out at least one essential factor, making it incomplete.
