Webinar Summary:
Currently at version 3.0, the National Water Model (NWM) provides 24×7 guidance for streamflow and other hydrologic components used by NWS River Forecast Centers, the Federal Emergency Management Agency and other government entities, along with research and commercial sectors. Based on the WRF-Hydro software architecture, it has been rapidly upgraded through six versions via a partnership between the NWS Office of Water Prediction (OWP), the National Center for Atmospheric Research (NCAR) and the National Centers for Environmental Prediction (NCEP).
Building on NWM v2.2, NWM v3.0 became operational in summer 2023 and provides first-time total water level (TWL) forecasts for coastal areas of the CONUS, Puerto Rico, the U.S. Virgin Islands, and Hawaii. Complementing regional products, the system simulates the additive impacts of storm surge, tides and freshwater flow. For the first time, NWM v3.0 also features coverage for portions of Alaska.
This presentation will provide an overview of current NWM operations and details on enhancements to TWL simulation capabilities arriving with NWM v3.1. It will also preview the transition to the Next Generation Water Resources Modeling Framework (NextGen) with NWM v4.0, and detail the Flood Inundation Mapping (FIM) capabilities supported by the NWM.
Learning Objectives:
- Describe the overall features of the National Water Model.
- Recognize the role that the NWM and related downstream products play in the forecasting process.
- Describe forthcoming upgrades the NWM and the products it underpins.
