[GRASS-user] r.hazard.flood

[Leo Kris Palao]

Dear GRASS users,

I want to use r.hazard.flood module of GRASS but could not get it to work.
I am running it in the command console. My expression is:
r.hazard.flood map=myanmar_dem_modis flood=flood mti=mti

Below is the error that I am getting. I have also r.area installed.

The projection of my Map is in Sinusoidal. I have my GRASS installed via
the OSGeo4W installer, as I use this method to install QGIS.

I am using Windows 7 Professional OS 64-bit
My GRASS version is 6.4.3

Another question: Is there a GUI for this module in the Windows version of
GRASS?

Thanks,
-Leo
