Lidar-derived Beach Morphology (Dune Crest, Dune Toe, and Shoreline) for U.S. Sandy Coastlines
The U.S. Geological Survey (USGS) National Assessment of Coastal Change Hazards (NACCH) project aims to identify areas of the nation's coastline that are most vulnerable to extreme storms and long-term shoreline change. These assessments require coastal elevation data across diverse geographic regions and covering a time span of many years. The datasets published here, organized by individual field activity numbers (FANs), define the dune crest (denoted by DC in the feature_type attribute), dune toe (denoted by DT in the feature_type attribute), and shoreline (denoted by SL in the feature_type attribute) at 10 meters (m) intervals alongshore for each processed lidar elevation survey. Beach width and beach slope as calculated from dune toe to shoreline are also included at each shoreline location.

Lidar-derived Beach Volumes and Shoreline Change for New Jersey and New York
This data release defines beach volumes and shoreline change for each 10-meter-wide profile along the New Jersey and New York coastline. The profiles are derived from light detection and ranging (lidar)-digital elevation models (DEMs). These data support the National Fish and Wildlife Foundation (NFWF)-funded project entitled “Monitoring Hurricane Sandy Beach and Marsh Resilience in New York and N - Publications
National assessment of hurricane-induced coastal erosion hazards--Gulf of Mexico
Sandy beaches provide a natural barrier between the ocean and inland communities, ecosystems, and resources. However, these dynamic environments move and change in response to winds, waves, and currents. During a hurricane, these changes can be large and sometimes catastrophic. High waves and storm surge act together to erode beaches and inundate low-lying lands, putting inland communities at riskAuthorsHilary F. Stockdon, Kara S. Doran, David M. Thompson, Kristin L.
