Web-Based Hurricane Storm Surge & Flood Forecasting

Picayune, MS

INNOVATION

Automated software algorithm that produces bare earth Digital Elevation Models (DEM) using “variational analysis”
Variational analysis computes the most probable estimate from a variety of data sources. It makes more accurate storm surge models possible

AD CIRC computed storm surge for
Hurricane Camille using optimized
bare-earth DEM for Eastern Biloxi Bay

Absolute difference (in feet) for the Hurricane Camille storm surge simulation using optimized bare-earth DEM vs. USGS DEM

ACCOMPLISHMENTS

WorldWinds is currently incorporating the new bare earth results in the Coupled Ocean Atmosphere Mesoscal
WorldWinds will replace the topographic datasets within COAMPS, coupled with ADCIRC, a storm surge model developed by the Army Corps of Engineers, to create new storm surge atlases

COMMERCIALIZATION

WorldWinds is partnering with Intermap Technologies to incorporate its algorithm into Intermap products for the orthorectification of satellite and airborne imagery
WorldWinds is selling output from the COAMPS weather model to be transmitted over XM Satellite via a subscription service, with mariners as the primary audience

GOVERNMENT/SCIENCE APPLICATIONS

Variational analysis has been successfully applied to geosciences, meteorological, and engineering applications within the NASA Earth Science Directorate
Federal and state agencies are evaluating the technology for use in evaluating rainfall effects, flash flood mapping, overlaid roads, and detailed coastline information
