Abstract:
The data base contains Mean Higher High Water (MHHW) baselines for Great Bay, Piscataqua River, embayment zones, and the open ocean for the New Hampshire seacoast region. The data are based on LiDAR data collected in 2011 and were derived using MHHW levels by zone, as reported by AECOM in their report entitled "SEA LEVEL RISE MAPPING NEW HAMPSHIRE OPEN COAST, PISCATAQUA RIVER, AND GREAT BAY", December, 2013 (see http://granitweb.sr.unh.edu/MetadataForViewers/NHCoastalViewer/RelatedDocuments/Sea_Level_Rise_Narrative_rev20150106_FinalReport.pdf). The data base contains 3 feature classes representing MHHW contour lines (MHHW_contours), MHHW polygons (MHHW_zones), and the delineation zones (Delineation_zones).
