[GRASS-user] Question about r.watershed and flow accumulation grid

[Thomas Adams]

Hello all!

I'm making use of the flow accumulation grid in GRASS 6.4.5 generated from
r.watershed using the SFD (D8) flow algorithm. The DEM has a 250m spatial
resolution. What I'm getting is a break in the flow accumulation in a few
locations which is causing me serious problems with subsequent processing
(with help from some here, I have put together some scripting to generate a
pixel connectivity file for a distributed hydrologic model).

Besides going to a higher resolution DEM, are there any thoughts as to how
I can eliminate these flow accumulation breaks?

Thank you,
Tom
