I've been running the SDR model successfully. My output rasters were successfully georeferenced and visualizing properly in ArcGIS, however their XY coordinate system was different than my input rasters (input rasters were all projected in NAD83 StatePlane, outputs were in Lambert_Conformal_Conic_2SP). Regardless, everything seemed to be working. Without changing anything but K and R units, all of the sudden my output rasters are shifted south of their actual locations, however vector outputs (watersheds_results_sdr_XXX.tif) are still properly georeferenced. XY coordinate system of my shifted output is all of the sudden matching my input NAD83 StatePlane coordinate system.
