RUSLE 2

Updated 07/12/2012

Revised Universal Soil Loss Equation, Version 2 (RUSLE2)

RUSLE2 is used to evaluate potential erosion rates at specific sites as well as guide conservation and erosion control planning. It also provides economic information about fuel use and costs for specific crop management systems. RUSLE2 uses factors that represent the effects of climate, soil Erodibility, topography, cover management and support practices to compute soil erosion. Conservation planning concepts must be understood and implemented into the RUSLE2 program in order for this program to be used effectively.
