Selecting the Runoff Curve Numbers for
Different Soil Groups and Cover Types
Use the SCS Curve Number Editor to select the runoff curve numbers for various
cover descriptions and soil groups. All the curve numbers for hydrologic soil
groups A, B, C, and D that are presented in the TR-55 manual, Table 2-2, are
already available from this dialog box.
To select a runoff curve number
1 In the SCS Curve Number Editor, locate the CN value to use by using the
navigation buttons.
2 Double-click in the cell that contains the CN value you want to use.
3 Click OK.
Calculating a Composite (or Weighted) Curve
Number for More Than One Watershed or
Subarea
If a sub-drainage area contains a variety of different soil and cover types, then
you can use the Composite CN Editor to calculate a composite curve number for
the entire site. The composite runoff curve number (RCN) is a weighted average
of the various Curve Numbers within the drainage area.
For more information on computing weighted CNs and other curve number
limitations, see the SCS TR-55 manual, Chapter 2, Estimating Runoff.
