I have just now submitted a bunch of fixes for r.basin, see<br/>
<br/>
<a href="http://trac.osgeo.org/grass/changeset/62672" target="_blank">http://trac.osgeo.org/grass/changeset/62672</a><br/>
<br/>
Please try again...<br/>

Do you mean 33 arcseconds? Otherwise it would be something like 30km pixels :-)<br/>

<br/>
Perhaps you can find a DEM in a metric projection for your study area<br/>
which would save you some times?<br/>
