Version 5.3.0 of the Community WRF-Hydro® source code is consistent with the NOAA National Water Model (NWM) v3.0 code in operations plus the following additions and fixes:
New features:
- Added impervious runoff scheme
- New new
nexpspatial parameter - Added option for Crocus snowpack/glacier model (see additional licensing terms)
- New channel option to bypass channel solver and output inflows
- New spatial snow parameters
Model physics fixes/updates:
- Array boundary fixes in channel routing
- Improved performance of nudging routines
- Correct minimum slope limit
- Corrected a situation where NaNs could be introduced in Muskingum-Cunge solver
- Moved SWE max limit to MPTABLE parameter
- Fixed energy NaNs over large snowpacks
- Miscellaneous RFC Reservoir fixes
- Moved overland roughness calculation outside of time-dependent disaggregation
- Improvements of Xinanjiang soil moisture scheme
- Added ‘scrape’ to domain edge so water doesn’t accumulate non-physically
Updated coupling infrastructure:
- Updated WRF coupling
- Updated NUOPC Cap coupling
Code-level updates that do not affect model physics:
- Removed unnecessary, harmless error messages
- Updated makefile targets to include
debug,install, andtest - Removed dependency on Dask from automated tests
- Update other dependencies in testing to newest versions
