[GRASS-user] grass-user Digest, Vol 118, Issue 18

Mon Feb 15 02:46:12 PST 2016

Hi Rengifo,

The issue is unfortunately more than just the GUI. You would be able to run the module on the command line if that was the case, but not even “r.terraflow --help” will give you any output. However, I am pretty sure r.watershed will provide you with what you are looking for and it is also able to handle huge datasets!

BTW: The paper you reference is a bit old. I recommend having a look at this:
sil.uc.edu/pdfFiles/.../JasiewiczMetz2011GRASS.pdf

As for you specific project:
The “Stream Power Index” might be of interest for you. It got implemented in r.watershed after we ran the module (and after the article above got published), so that output is missing from the data we have...

Anyway, I will see what I can do to provide you with the data (input and output, which includes TCI). Of course we used MFD, but we did not account / weight surface runoff as we had no suitable runoff data for the neighboring countries (and also for Norway we only had aggregated data for 1961-1990 with 1km2 resolution)...

I will check if our FTP is able to handle the amount of data and contact you offline when I have a solution for that...

Hilsen,
Stefan

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".

HTH,

Stefan

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
