erosivFUN | R Documentation |
This function assumes an algebraic relationship between annual rainfall amounts and rainfall erosivity. The relationship has constants that may depend of certain regions.
erosivFUN(rain,A,B, model)
rain |
annual rainfall amounts in mm or Fourier index of rainfall |
A |
independent constant of the algebraic relationship between rainfall mounts and erosive energy (Energy=A+-B*rainfall) |
B |
rainfall coefficient of the algebraic relationship between rainfall mounts and erosive energy (Energy=A+-B*rainfall) |
model |
model defining the algebraic relationship between rainfall mounts and erosive energy. The model can be linear, power, logarithmic, Fourier, and exponential |
rainfall erosivity in MJ mm/ha/hr/yr
