Directory structure

Standard RHESSys directory structure

Generally you will set up a main directory workspace. Within that directory, set up the following sub-directories:

worldfiles worldfiles/templates flowtables tecfiles clim defs scripts out out/cal out/cal/sims obs post auxdata

When you create a mapset in GRASS, you will tell GRASS where to store it (within this same main directory workspace), and an additional sub-directory that contains the GRASS mapset will be created for you at the same level as the above.
