thank you

I looked the site you directed me.
Compared to r.watershed, r.terraflow produced stream map much faster. But
there  seems to be broken streams. Although I lowered the accumulation 
threshold value, broken streams still exist.
How can I get unbroken streams using r.terraflow.

Since I worked on DEM quality, I saw some interesting features
in the other part of the site. Does "DEM vs. Field Slope" show
DEM's quality.

regards
