Water Resources Program 2019-2021

Key Project:

Pilot Real-time Flood Inundation Mapping Using National Water Model


Priority Water Resources Need:

Improve Community Flood Preparedness


Project Location:

Location TBD, targeting West Branch Susquehanna Subbasin


Project Lead:

Project Description:

digital elevation model Building on the long history of developing static inundation map libraries for National Oceanic and Atmospheric Administration’s (NOAA) National Weather Service forecast points across the basin, this project will seek to utilize recently developed Geographic Information System methodologies in concert with output from NOAA’s National Water Model to produce “on the fly” mapping readily disseminated to emergency managers and the general public in near real-time. This product differs from a traditional static inundation map library in that the map product does not require a NWS Forecast point to provide a frame of reference and will display inundation based on forecast discharge related to a specific rainfall forecast. Additionally the map product is adaptable to changing forecasts over time.


Challenges:
  • Providing accurate representation of expected flooding
  • Model calibration and on the ground verification of model results
  • Processing forecast data to produce mapping in real-time

Key Milestones:
  • •  Mapping SOW/Stakeholder Engagement
    (December 2019)
  • •  Conditioned Digital Elevation Model
    (June 2020)
  • •  Map Prototype
    (December 2020)
