Universal Soil Loss

Written by Jerry Ratzlaff on . Posted in Geotechnical Engineering

Universal soil loss, abbreviated as USLE, predicts the potential long-term average annual soil loss per unit area.


Universal Soil Loss Formula

\(\large{ A  =  CP \; R \; l \; S \; K   }\)   


\(\large{ A }\) = estimated annual soil loss

\(\large{ CP }\) = conservation management and land cover practices

\(\large{ R }\) = rainfull and runoff factor (the summed erosive potential of all rainfall events in a year)

\(\large{ l }\) = slope length

\(\large{ S }\) = slope steepness

\(\large{ K }\) = soil erodibility factor (units of soil loss per unit of soil erosivity)
