Hi GRASS User's:
I have streams map which is an output of r.watershed program. How can I find
the length of drainage network to determine drainage density of the watershed
from this map?
Thanks in advancing for your help

One way that I've estimated stream length is to divide the area of the stream
image by the width of a cell.
