Abstract:
The Community 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 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 5.2). It will also introduce new pre- and post-processing tools to support the WRF-Hydro community and include information on the numerous online community support and education outlets.

This presentation will also provide a high level overview of the building blocks for a new community modeling testbed for integrated analysis and prediction, “HyTEST: Hydro-terrestrial Earth Systems Testbed”. HyTEST is a new partnership between NCAR and the United States Geological Survey (USGS) which hopes to establish a long-term framework for governance, objective criteria for model benchmarking and evaluation, and evidence-based decision making.
