Hello All,
I am new to GRASS but have been using GIS (mainly ESRI products) for quite a few years. I am trying to learn how to use GRASS to carry out hydrology related analyses. Currently, I am trying to use the r.watershed command to delineate the basins for a watershed. My question is, how long would you expect it to take to run? I am wondering if I am doing it wrong or if it just takes longer than I would expect. The DEM is about 170MB TIFF before I import it to GRASS. I have tried to run it a few times using different options, each time letting it run for 3 - 4 hours before killing it. I have tried both the -m and -4 flags. Any input would be appreciated.
