NOAA National Water Model (NWM)
The NOAA National Water Model (NWM) is an operational hydrologic modeling framework run by the NOAA/NWS Office of Water Prediction that produces continuous, gridded streamflow and hydrologic forecasts for the continental United States. The NWM simulates and forecasts water in streams and rivers on the NHDPlus reach network, delivering analysis-and-assimilation, short-range, medium-range, and long-range forecasts used for flood prediction and water resource applications. The Urban Flooding Open Knowledge Network (UF-OKN) uses NWM streamflow forecasts as the operational, national-scale forecast source that drives its real-time flood-risk information.
