Talk Description:

As a significant step forward to transform NOAA’s water prediction services, NOAA implemented a new National Water Model (NWM) Version 1.0 in August 2016. A continental scale water resources model, the NWM is an evolution of the WRF-Hydro architecture developed by the National Center for Atmospheric Research (NCAR). It represents NOAA’s first foray into high performance computing for water prediction and will expand NOAA’s current water quantity forecasts, at approximately 4000 U.S. Geological Survey (USGS) stream gage sites across the country, to forecasts of flow, soil moisture, evapotranspiration, runoff, snow water equivalent and other parameters for 2.7 million stream reaches nationwide. This new guidance will be provided to NOAA's River Forecast Centers around the country and other field offices, along with guidance for evaluation and validation, and tools to visualize these data and enhance decision support. Initially, a subset of these data will be available via NOAA’s Office of Water Prediction web site and the full output of the NWM simulations will be available via the NOAA Operational Model Archive and Distribution System (NOMADS). These enhancements in turn will improve NWS' ability to deliver impact-based decision support services nationwide through the provision of short through extended range, high fidelity “street level” water forecasts and warnings. Subsequent planned out-year enhancements to the NWM include the expanded assimilation of anthropogenic data, an operational nest to provide higher resolution forecasts needed for inundation mapping, and tackling the deeper challenges associated with drought and other water resources issues. The NWM is a NOAA-led interagency effort that relies on the National Hydrographic Dataset of the USGS and EPA, as well as the National Streamflow Information Program of the USGS. Its development continues to be advanced in partnership with NCAR, and a partnership with the Consortium for the Advancement of Hydrologic Sciences, Inc. (CUAHSI) and the National Science Foundation. This presentation will highlight the policy, programmatic, and service transformation of NOAA’s water resources mission with the NWM. 

CUAHSI's Fall 2016 Cyberseminar Series on the National Water Model!

The cyberseminar series discusses the National Weather Services’ vision for the National Water Model, as well as provide an overview regarding the underlying technology of the model. Additionally, highlights from last year’s Summer Institute will be presented, followed by information regarding the plans for next year’s Summer Institute and how interested community members can be involved.
