A reconnaissance study distinguishes coastal areas of the northeastern U.S. (approx. Virginia to Maine) that will experience an inundation-dominated response to sea-level rise from those that will respond dynamically due to physical and bio-physical sedimentation and erosion processes. Areas that will be dominated by inundation include urban regions of intense development and/or coastal engineering, as well as bedrock coasts. Areas that will respond dynamically include beaches, unconsolidated cliffs, barrier islands, and wetlands. Distinguishing which processes are relevant to sea-level rise impacts in these areas aids prioritization of scientific research and decision support efforts.
