[GRASS-user] Here is the detailed output I'm getting from r.inund.fluv

All:

Below is the detailed output I’m getting from running r.inund.fluv on Ubuntu 13.10, GRASS 6.4.3.

My DTM is 30m x 30m (the best I can do at the moment) and distances between cross-sections is on the order of 300-500 meters – could this explain my results (no maps are created)?

Regards,

Tom

Could you please provide an example based on the North Carolina
dataset? Then it is easier to reproduce.

Markus,

I don’t think I can do this because it would require setting up a hydrodnamic unsteady flow model for a stream in the NC data set and preparing the necessary input file for r.inund.fluv once I had successfully run the model. I can not see in the NC data set that any of this is available and I am just not in a position to undertake the effort. What is missing is a georeferenced channel centerline with the associated modeled water surface elevation profile.

Thank you for your help.

Yes, ok. Then I see two options
- shell debugging with -x option, see
  http://grasswiki.osgeo.org/wiki/GRASS_Debugging#Shell_script_debugging
- try to contact the authors of r.inund.fluv who will know it better
than most of us.

Markus,

Thank you for the suggestion; attached is the detail using the -x option.

Cheers!
