What does RUSLE stand for?

What does RUSLE stand for?

• A. Revised Universal Soil Loss Equation
• B. Revised Universal Sediment Loss Evaluation
• C. Relative Universal Soil Loss Estimate
• D. Regular Universal Soil Loss Equation

Answer: (A)

The main idea here is recognizing the standard name of a well-known soil erosion model. RUSLE expands and updates the original erosion equation, so the correct expansion is “Revised Universal Soil Loss Equation.” This reflects that it’s an updated version of the Universal Soil Loss Equation used to estimate long-term average annual soil loss due to rainfall and runoff, incorporating factors like rainfall erosivity, soil erodibility, slope length and steepness, cover-management, and support practices. The other phrases don’t match the established terminology used in soil erosion prediction, so they aren’t the correct expansion.
