dear grass community,thanks a lot for the hints. Yes, indeed it was under hydrological modelling. But I still keep getting an error when I try to open r.terraflow from the GUI, which is the reason I thought , in the first place, it was not installed.
Here is the error hope someone kan help me with it.
Traceback (most recent call last):
File "C:\OSGEO4~1\apps\grass\grass-7.0.3\gui\wxpython\lmgr
\frame.py", line 776, in OnMenuCmd
GUI(parent=self, giface=self._giface).ParseCommand(cmd)
File "C:\OSGEO4~1\apps\grass\grass-7.0.3\gui\wxpython\gui_
core\forms.py", line 2354, in ParseCommand
raise gcmd.GException(e.value)
core.gcmd
.
GException
:
Unable to fetch interface description for command
'r.terraflow'.
Details: C:\OSGEO4~1\bin\python.exe: can't open file
'r.terraflow': [Errno 2] No such file or directory
It basically says that tha file is not available.
As for the question from Blumentrath Stefan:
Yes, Stefan I am working with Norwegian data The same resolution as you. I am using DTM10 from Statens Kartverk. Why r.terraflow? Well, for this purpose it seems to be the best algorithm.
Currently, I am proposing a combined approach (geomorphons+TCI (r.terraflow based), for locating areas, where our potential mass movement modelling (based on flow-r) fails to model the outreach of those mass movements. Specifically, I am looking at areas on alluvial fans located just below the footslopes, where phenomena like debris flows might change their rheological behavior, due to changes in the slope gradient of the alluvial. r.terraflow is use to model water accumulation and TCI in these areas. The idea is to establish some sort of threshold, using the TCI, where potential flows paths can be delinated as an extension of the alredy existing model. e.g town of Kvam
Basically, these areas are looked upon as flood areas, and for this purpose seems r.terraflow to be the best, according to some authors https://books.google.no/books?id=svwfypEvPwEC&pg=PA94&lpg=PA94&dq=terraflow+panam%C3%A1&source=bl&ots=NN5mfSaXm4&sig=UX4mZ-6fB5aYdKGKGLC0HQRfmdc&hl=no&sa=X&ved=0ahUKEwi3vfOS3fTKAhWrJZoKHfY-CqoQ6AEIIzAA#v=onepage&q=terraflow%20panam%C3%A1&f=false
However, I would appreciate to get a copy of the data you refered to, given you used MFD and not SFD to calculate it, since I am interested on diffuse waterflow and not chanalised one.
Thanks in advance

Hi,
I think its comes with the standard installation of GRASS. I find it,
and most likely you too, under_
"raster --> hydrologic modeling --> Flow accumulation".

Hei Rengifo,
See: http://osgeo-org.1560.x6.nabble.com/C-and-libLAS-modules-broken-in-7-0-3-in-winGRASS-tt5249518.html#a5249942
Any particular reason for using r.terraflow and not r.watershed?
I assume you work on Norwegian data!?
In a project together with NTNU, UiO, SLU ... we ran r.watershed on a 10m terrain model covering entire Fenoscandia (unfortunately we did not have data from the Russian border). If you are interested, I can provide you with the related data...
Beste hilsen,
Stefan

Both modules work perfectly on the last compilation of GRASS GIS 7.0.3 for
W10.
Last standalone with those updates is available on the GRASS website.
Thanks to Martin Landa

Dear friends, I hope to be good! I use a translator, I excuse my bad
writing in English
I have a question, it is possible if I have an image or aerial photo of oil
palm to cite one case performed automatically count plants?
attached a sample image
Muchas gracias
