==Automatically Calculating USLE using GISus-M== |
|||
=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. |
