Mapping Areas Potentially Impacted by Sea Level Rise


Overview

The science surrounding global and regional projections of future sea level has grown rapidly in recent years, and depicts a worsening prospect of substantial amounts of sea level rise over this and following centuries. As a result, assessing and anticipating potential sea level rise impacts to coastal areas is now of increased importance.

Analysis of elevation data in the context of projected sea level rise serves as one of the fundamental components needed to fully identify low-lying coastal areas that may confront impacts such as accretion and erosion, temporary flooding, and permanent inundation. Our work has centered on the analysis of digital elevation models (DEMs) to help delineate low-elevation coastal areas.

We provide results from our elevation data analyses through the Web map visualization tools below. Analyses based on DEMs with a horizontal resolution of 1 km give an overview of low-lying coastal areas at regional scales. Analyses stemming from DEMs with a horizontal resolution of 30 m allow for viewing at more local scales.

Details and limitations of our methodology and the elevation data we use are described in Weiss et al. (2011).
