Transforming National Oceanic
and Atmospheric Administration
(NOAA) Water Prediction:
The New National Water Model

n response to growing stakeholder demands for enhanced
and integrated water resources forecasts and services, to
address increasingly complex societal issues, NOAA has
begun a transformation of its operational water prediction
capabilities. Mounting threats to water security stemming from
population growth and economic development are stressing
water supplies and degrading water quality; a changing climate
is further impacting water availability and quality, increasing
uncertainty; an aging water infrastructure is forcing critical,
expensive decisions; and socio-economic risks of floods and
droughts are escalating. Recent engagements with water
resources stakeholders across the United States revealed the
need for consistent, high space and time resolution, integrated
water analyses, predictions and data to address critical unmet
information and service gaps related to floods, droughts, water
quality, water availability and climate change.

January 2018

As a significant step forward to transform
NOAA's water prediction services, NOAA
implemented version 1.0 of a new National
Water Model (NWM) 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) and its
international collaborator community. WRFHydro is a community-based, Earth System
Modeling Framework (ESMF)-compatible
hydrologic modeling system.
The NWM is a NOAA-led interagency
effort that leverages model topology within
the National Hydrographic Dataset-Plus
(NHDPlus) version 2, from the U.S. Geological
Survey (USGS) and Environmental Protection
Agency (EPA). Additionally, the NWM ingests
and assimilates streamflow data each hour
from approximately 8,000 gages in the USGS
National Streamflow Information Program.
The development and implementation of NWM
Version 1.0 was the result of strong collaboration
