erosionPrerequisites-RPhosFate-method function

Erosion prerequisites

Calculates and writes capped slopes, L- and RUSLE S-factors (equations for summer conditions and slopes $≥$ 15 ft) to disk.

## S4 method for signature 'RPhosFate'
erosionPrerequisites(x)

Arguments

• x: An S4 RPhosFate river catchment object.

Returns

An S4 RPhosFate river catchment object and side effects in the form of raster files.

Examples

# temporary demonstration project copy
cv_dir <- demoProject()
# load temporary demonstration project
x <- RPhosFate(
  cv_dir = cv_dir,
  ls_ini = TRUE
)

x <- erosionPrerequisites(x)
