Hi all,
I have been trying to run GRASS7 module r.damflood using the following
datasets
[https://drive.google.com/drive/folders/0B2Yx_1shUSx3VThlY3BrV1JyWjg?usp=sharing],
with this command:
r.damflood --overwrite --verbose elev=dem lake=water_depth
dambreak=dam_breach manning=manning tstop=3 deltat=1 h=b_depth vel=b_vel
hmax=b_mwd vmax=b_mwv imax=b_mi wavefront=b_wf
To make it easier, the lake has a constant depth.
As far as I can understand, the rasters should be correctly built, but
the outputs of r.damflood are obviously wrong (rasters with nodata or
one category = 0; at second 1 the depth raster is half the lake's size
(s00.png, s01.png)and at second 2, it completely disappears).
During the processing, I get the Courant-Friedrich-Lewy stability
condition warning message.
If I try to chose as computational method for initial velocity
estimation, uniform drop in of lake or small dam breach, I get the
following error "ERROR: Don't find the dambreak - Please select a
correct map or adjust the computational region".
Does anyone have an idea what could be the reason of these results,
please? Any suggestion would be highly appreciated.
Cheers,
Codrina
