Detrmining Erosion Cover Factor (C Factor) from Vegetation Cover Fraction
Description
To estimate erosion model cover factor from vegetation cover fraction
Usage
VegCOV(pcover, model="cai")
Arguments
pcover |
percent vegetation cover |
model |
model for estimating C factor from percent vegetation cover |
Details
This function can be used to estimate the C factor for erosion modelling by use of percent vegetation cover. The function contains five models: cai, xu, hurni, jin, and liu. When the percent cover ('pcover') is given and the model to use (e.g., 'cai'), the function returns dimensionless C factor for erosion modelling. C factor ranges between 0 and 1 (0< cfactor<=1)
Value
A numerical value between 0 and 1
Note
The function does not accept percent cover values that are less than 0 and more than 100.
