[GRASS-user] r.sim.water newbie question

Hi - I’m trying to run r.sim.water on a DEM of the Santa Clara Valley, in state plane feet. The DEM is fine, and gives a nice visual output from r.watershed .

I wanted to just try the defaults, using dx and dy from r.slope.aspect

r.sim.water -t --overwrite elevin=grid20061@PERMANENT dxin=dx@PERMANENT dyin=dy@PERMANENT depth=depth_1 disch=discharge_1 err=sim_error1

I don’t get any results.

suggestions/RTFMs welcomed

thanks -

Chris

finally pushed got back to this; set x/y resolution to 100 feet and gave it
500K walkers and am now getting results!
