Inquiry about the difference in routing physical processes between UDMP-on and UDMP-off configurations in WRF-Hydro

[zed li]

Hello everyone,

I am currently working with the WRF-Hydro model, and I am using the Muskingum-Cunge method for channel routing. I have a question regarding the hydrological processes when the User-Defined Mapping (UDMP) option is enabled versus disabled.Aside from the differences in sub-basin delineation and river network structure, I would like to know whether there are any differences in the physical processes of routing between these two configurations.

Thank you very much for your time and assistance.

Best regards,
