Erosion prerequisites

Calculates and writes capped slopes, L- and RUSLE S-factors (equations for summer conditions and slopes \(\geq\) 15 ft) to disk. Weighted flow accumulations less than one are set to one for the calculation of the L-factors.

# S4 method for RPhosFate
erosionPrerequisites(x)

Arguments
