Coastal Erosion: USGS National Shoreline Change - North Carolina

Introduction

Coastal erosion is a significant climate risk that refers to the process by which coastlines gradually wear away due to the impact of natural forces such as waves, tides, and currents, as well as human activities. It can result in the loss of protective beachfronts, increased flooding, and damage to coastal ecosystems and infrastructure. Understanding and monitoring coastal erosion is crucial for coastal management, planning, and mitigation strategies. The USGS National Shoreline Change project contributes to this understanding by providing critical data on shoreline positions and changes over time.[1]

Dataset Overview

The USGS National Shoreline Change offers valuable lidar-derived data on mean high water shorelines and associated changes, specifically focusing on the North Carolina coast. This dataset is a vital resource for documenting coastal change and aiding in the management and preservation of vulnerable coastal zones.[2]

Summary

The USGS has compiled shoreline data for over two decades, creating a record of historical shoreline positions to monitor and analyze national shoreline evolution. The most recent dataset encompasses a newly extracted mean high water (MHW) shoreline from lidar data in 2017 and provides rates of change for both long-term and short-term assessments.[4]
