Is the LANDUSE.TBL or VEGPARM.TBL used for surface roughness?

Surface roughness is calculated based on vegetation fraction, and min and max values are defined in the VEGPARM.TBL for the Noah LSM. Look for details in phys/module_sf_noahlsm.F. The simple slab model (sf_surface_physics. = 1), however, uses the values defined in the LANDUSE.TBL.
