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!

Apologies for the long delay in response while our team tended to time-sensitive obligations. Thank you for your patience. Since it's been a while, can you let me know if you've figured out the answer to your questions or if you still need assistance? Thanks!

Thank you for the reply.

I still need help with the first question: "Will editing the URBPARM.TBL file be enough to apply those changes?"
However, through some trial and error, I found that when only one urban class is present in the domain, WRF uses the urban parameters from the High-Density Residential (Hi-dens Res) category.


Thank you

I'm glad you were able to figure out the second question. For the first, see this previous post, which I believe addresses your question.
