How to change urban morphology with one urban class and BEP (sf_urban_physics = 2)?

[blossom_]

Hi,

I’m running WRF with sf_urban_physics = 2 (BEP scheme), and my domain contains only one urban class.

I want to modify the urban morphology (e.g., building height, street width, urban fraction, etc.) for this class.
Will editing the URBPARM.TBL file be enough to apply those changes?

Also, URBPARM.TBL contains morphology for three urban categories (Low-dens Res, Hi-dens Res, Commercial).
When only one urban class is present in the domain, which URBPARM entry does WRF use by default (low, high or commercial)?

Thanks!
