What is USLE

The Universal Soil Loss Equation (USLE) allows one to calculate the long-term average soil erosion rates for mainly agricultural lands. When calculating the USLE, five major factors must be taken into consideration:

A = R * K * LS * C * P

Where:

  A is the potential long-term erosion rate in tonnes per hectare

  R is the rainfall run off factor

  K is the soil erodibility factor

  LS is the slope length-gradient factor

  C is the crop factor

  P is the conservation practices factor

Classically, the LS factor was estimated by hand, with complex slopes being broken down into segments. However with the advent of high-resolution open source data, such as South-Western Ontario Orothophotography (SWOOP), LS factor can be calculated through computational means.
