Description:
Abstract:
The data base contains predicted sea level rise extent GIS layers along the open coast of New Hampshire, the Piscataqua River, and Great Bay for eight scenarios, as follows:

MHHW_plus_2_ft_slr: Mean higher high water + 2' sea level rise MHHW_plus_4_ft_slr: Mean higher high water + 4' seal level rise MHHW_plus_6_ft_slr: Mean higher high water + 6' seal level rise MHHW_plus_8_ft_slr: Mean higher high water + 8' seal level rise MHHW_FLOOD_plus_2_slr: Mean higher high water + one percent annual chance flood + 2' seal level rise MHHW_FLOOD_plus_4_slr: Mean higher high water + one percent annual chance flood + 4' seal level rise MHHW_FLOOD_plus_6_slr: Mean higher high water + one percent annual chance flood + 6' seal level rise MHHW_FLOOD_plus_8_slr: Mean higher high water + one percent annual chance flood + 8' seal level rise

The four data layers that incorporate the 100-year flood are based on the April, 2014 preliminary Digital Flood Insurance Rate Maps (DFIRMs) for Rockingham and Strafford Counties.

Purpose:
The data are intended to provide communities, coastal managers, scientists, and the public with a preliminary assessment of the extent of potential sea level rise.

Process_Description:
The LIDAR dem surface was hydro flattened by setting all pixels within the MHHW POLYGONS to a value of -1.6404-feet (-0.5-meters). The -1.6404-foot elevation was chosen to match that which is described in the NOAA Office for Coastal Management document "Detailed Method for Mapping Sea Level Rise Inundation". All pixels not within MHHW POLYGONS retained pixel values of the LIDAR dem.

Process_Step:
Process_Description:
Sea Level Rise rasters were developed by ESRC using (for the most part) the methodologies established by AECOM as reported in the related document: "Sea Level Rise Mapping Data - New Hampshire Open Coast, Piscataqua River, and Great Bay". The one departure was that the water elevations for the open ocean and waters connected to it were set at -1.6404 feet (-0.5 meters as described in the NOAA Office for Coastal Management document "Detailed Method for Mapping Sea Level Rise Inundation"). This data is reflected in HYDRO-FLATTENED LIDAR. In addition, several disconnected polygons (but greater than 1 acre) that were not believed to be hydrologically connected to the open ocean were deleted.
