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 nexp spatial 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, and test Removed dependency on Dask from automated tests Update other dependencies in testing to newest versions
