Risk Assessment of Archaeological Sites Using Lidar: Sea level Rise Modeling at Jamestown Island, VA
Author(s): Robert Chartrand
Year: 2017
Summary
Jamestown Island contains low-lying terrain with archaeological sites, known and unknown, threatened by sea level rise. Using data acquired from the United States Geological Survey (USGS), a Digital Elevation Model (DEM) was created using a Light Detection and Ranging Remote Sensing technique (LIDAR) to identify cultural sites and assist in planning for cultural remediation. Four scenarios of sea level rise modeling were created based on historic trends and projected environmental events compiled by the Virginia Institute of Marine Sciences (VIMS). A time frame to demonstrate land submergence beginning in 2020 was conducted in four 20-year-cycles. Using the most extreme VIMS scenario, submergence of Jamestown Island by 90.43% in the year 2100 was demonstrated. LIDAR proved to be an essential tool for risk assessment of cultural sites due to sea level rise.
