Assessing Nor'easter vulnerability for three New England parks
The project investigates the impacts of Northeasters, colloquially referred to as Nor’easters, and other extratropical storms at three coastal parks, Acadia National Park (ACAD), Boston Harbor Islands National Recreation Area (BOHA), and Cape Cod National Seashore (CACO) amplified under a changing climate and higher sea level. The team analyzes vulnerability to Nor’easters, looking at inundation, and wind damage. The results are presented through maps and three-dimensional visualizations of projected future impacts at higher sea level rise (SLR) that will help better plan for resource management, maintenance, and visitor access and safety.
This project adopted the ADvanced CIRCulation (ADCIRC) hydrodynamic model used by NOAA’s Extratropical Surge and Tide Operational Forecasting System (ESTOFS) to provide real-time guidance for storm surges and tides at the US coastlines. Since the resolution of HSOFS is not sufficient to accurately represent the bathymetry, topography and coastlines at ACAD, BOHA and CACO ational k one of the major efforts was the modification of the ADCIRC mesh to increase its spatial resolution in the New England area.
