Which statement about RUSLE is true?

• A. It estimates soil loss
• B. It measures water quality
• C. It predicts vegetation growth
• D. It estimates rainfall intensity

Answer: (A)

RUSLE, the Revised Universal Soil Loss Equation, is used to estimate the average annual rate of soil loss due to sheet and rill erosion from rainfall and runoff. It combines factors for rainfall erosivity, soil erodibility, slope length and steepness, cover-management, and practices to yield an estimate of soil loss per area per year. It does not measure water quality, predict vegetation growth, or directly estimate rainfall intensity (though rainfall erosivity is a component related to rainfall). Therefore, the statement that RUSLE estimates soil loss is the correct description of what this tool does.
