The WRF-Hydro modeling system is publicly available and provides researchers and operational forecasters a flexible and extensible capability for performing multi-scale, multi-physics options for hydrologic modeling that can be run independent or fully-interactive with the Weather Research and Forecasting (WRF) atmospheric model. The core WRF-Hydro physics model contains very high-resolution descriptions of terrestrial hydrologic process representations such as land-atmosphere exchanges of energy and moisture, snowpack evolution, infiltration, terrain routing, channel routing, basic reservoir representation and hydrologic data assimilation. Complementing the core physics components of WRF-Hydro are an ecosystem of pre- and post-processing tools that facilitate the preparation of terrain and meteorological input data, an open-source hydrologic model evaluation toolset (Rwrfhydro), hydrologic data assimilation capabilities with DART and advanced model visualization capabilities.
The National Center for Atmospheric Research (NCAR), through collaborative support from the National Science Foundation and other funding partners, provides community support for the entire WRF-Hydro system through a variety of mechanisms. This presentation summarizes the updates to and enhancements within the newest version of the model source code (Version 5) and its convergence with the National Water Model code base (the first operational, high-resolution, hydrologic prediction model to be implemented across the continental United States), as well as the enhanced user support and educational training capabilities that are being developed for the Community WRF-Hydro modeling system. These products and services include a new website, open-source code repositories, documentation and user guides, test cases, updated preprocessing tools, online training materials, live, hands-on training sessions, an email list serve, and individual user support via email.
