Modeling the Impact of Anthropogenic Sea-Level Rise and Storm Surge on Coastal Archaeological Sites

Summary

This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology.

This paper analyzes the impact of projected sea-level rise as a result of anthropogenic climate change on coastal archaeological sites in the state of Georgia. Coastal sites and environments are at increasing risk of erosion, inundation, and submersion due to projected sea level rise of 0.25-0.30 meters by 2050 and up to 2.1 meters by 2100, along with higher rates of coastal flooding events (NOAA 2022). Modeling the impacts of these climate changes requires the use of many geospatial datasets, including those related to geomorphology, land use and cover, and operationalization of flooding and storm surge projections according to local conditions. This paper describes the development of a custom GIS model to predict the impact of these changes on coastal archaeological sites from the Georgia Archaeological Site File in order to provide a sophisticated prediction of how the archaeological record will be impacted by future sea level rise and storm-based damage.
