Due to the significant number of updates since the previous WRF-Hydro v3.0 release, users with existing domain and setup files will need to adapt some files to be read by the new code. The significant updates and delayed release are attributed to the merging of the WRF-Hydro community model code base with the National Water Model (NWM) code base to provide access to many of the features of the NWM. Details regarding WRF-Hydro changes can be found here.

Below are some high level highlights of major changes. More information can also be found in the WRF-Hydro documentation available here on our project website.

  • New capability to aggregate and route flow with user-defined mapping over NHDPlus catchments and reaches
  • New capability to specify key hydrologic and vegetation parameters in 2 dimensions (and 3 in the case of soil properties).
  • New Noah-MP surface resistance formulation that improves snowpack simulation.
  • Updates to Noah-MP infiltration scheme to better handle high intensity rainfall events in fast-draining soils.
  • Significant improvements to model output routines, including full CF compliance, new capabilities for applying internal scale/offset and compression to reduce file sizes, and built-in coordinate information to allow outputs to be read natively in GIS environments.
  • New capability for streamflow nudging data-assimilation for the Muskingum-Cunge method.
  • New capability for engineering and regression testing is now available for WRF-Hydro. More information can be found here.
