Composite CN (Curve Number) with Unconnected Impervious Area
Description
This function computes the composite CN (Curve Number) for unconnected
impervious areas and total impervious areas less than 30 percent.
Usage
uc_composite_CN(pervious_CN, impervious, R)
Arguments
pervious_CN
numeric vector containing the pervious runoff curve number
impervious
numeric vector containing the percent imperviousness
R
numeric vector containing the ratio of unconnected impervious area to total impervious area
Value
the Composite Runoff Curve Number as a single numeric vector, in the
range [0, 100]
