EROSIVITY
ØSingle storm
-Energy x 30 minute intensity
-Fundamentally product of rainfall amount x intensity
ØAnnual-sum of daily values
ØAverage annual-average of annual values
ØDaily value=average annual x fraction that occurs on a given day
The core part of RUSLE2 is that it estimates soil loss from an individual storm.
The linear relationship between erodibility and soil erodibility allow simple mathematical approaches to integrate the variables over time.
