[GRASS-user] Area between drainage networks

Hello everyone, 

I'd like to obtain the area between two drainage networks. The difference
between them is due to different calculation methods. 

The image above illustrates the methodology of mesuring the "error" between
two drainage networks.

Each one of the drainage networks is in a shapefile, and I need the sum of
all the areas between the segments of the drainage networks, so that I can
mesure the difference between them.

How could I do that with GRASS?

Thanks in advance.
