[GRASS-user] Itzi: units of length and flooded areas

[Rich Shepard]

Laurent,

   I appreciate that Iizi works in SI units and I have a question about the
basis for that. Specifically, in your tutorial section using mapcalc to
create a map of uniform rainfall you specify 'rain=100'. Is the 100 in mm/hr
or some other unit or rate?

   Your example figure, nc_itzi_tutorial_h_0020, appears to present water
depth after 2 hr of 100 mm/hr? rainfall in an unrestricted stream channel.
Is there a way of showing rainfall accumulation (flooding) if the watershed
outlet is blocked?

Thanks,

Rich
