REVISED UNIVERSAL SOIL LOSS EQUATION

APPLICABLE TOPOGRAPHY

ØSlope Length

-Best: 50 - 300 feet

-Moderate: 0 - 50 ft , 300 - 600 ft.

-Acceptable: 600 - 1000 feet

-NO: >1000 feet


	The range of applicability is determine by the availability of empirical data.
	RUSLE2 should not be applied to slope lengths longer than 1000 ft. The longest slope length used derive RUSLE2 was about 650 ft. Beyond 1000 ft is simply too much extrapolation.
	RUSLE2 can be applied to slope lengths as short as 1 ft.
