Currently, flowaccumulation and flow direction map are both being calculated in calc_subbas() and lump_grass_prep().
If would save lots of cimputational time, if r.watershed could re-use any exsisting maps. Currently, this doesn't seem to be possible though. Let's verify this, though.

calc_subbas() takes them as optional input if they already exist. I'm rather sure I paid some attention that r.watershed is not executed more often than necessary.
r.watershed wird bis zu 3 mal aufgerufen:
a) zur TEZG-Bestimmung nach Schwellenwert
b) zur TEZG-Bestimmung auf Auslasspunkt
c) zur Konstruktion der EHAs
Jedes mal wird flowaccum neu berechnet, weil r.watershed diese nicht bereits übernehmen kann. Wenn es eine Alternative zu r.watershed gäbe, die das könnte, würde das Einsparungen bringen.
