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.
