grass has been running for three days to create watershed related maps.
At this moment, it has been in this stage for a long time (almost one day):
~~~~~~~~~~
Running: /usr/lib/grass/etc/water/ram el="el_5" t=100 se="str_5" ha="hbas20_50"
SECTION 1a (of 5): Initiating Memory.
SECTION 1b (of 5): Determining Offmap Flow. Percent Complete:
SECTION 2: A * Search. Percent complete:
SECTION 3: Accumulating Surface Flow. Percent complete:
SECTION 4: Watershed determination.
SECTION 5: Closing Maps.
~~~~~~~~~
I am not sure if grass will be able to complete it's job ?
or
is it a good idea to cancel the job and start again with smaller region?
what do you suggest ?
regards
Ahmet Temiz

Congrats!
This is well known bug in GRASS by some users (i.e. me). GRASS will
never finish this watershed creation. You can safely ctrl-c it and
forget about it.

prcessing very large maps is quite slow with r.whatershed (I guess you are using this command!).
I suggest to give a try to r.terraflow, it has been created for large raster file processing....
Hope this help.

thank you
as far as I see r.terraflow does not produce half basin.
I need a module that creates half basin other than r.watershed.

as far as I see r.terraflow does not produce half basin.
I need a module that creates half basin other than r.watershed.
Looks like the while loop in raster/r.watershed/ram/close_maps2.c
line 38 is never satisfied.
Maybe same endless call to close_array_seg() is what causes bug #3112?
Things often report 98% when actually done as G_percent() is often
called in the wrong place or doesn't get called after exit. (e.g. watch
r.terrflow run) So it is likely it finished & then got stuck on the
cleanup step.
-- how big is the test region?
-- r.info: CELL map, DCELL map?
(idea- try a CELL version [r.mapcalc 'newmap=int(oldmap)'])
that's about as deep as I can look into it right now.
