National Assessment of Coastal Change Hazards

Introduction

Eroding sea cliffs along the Pacifica coast just south of San Francisco, CA during the 1997-98 El Nino winter.

Coastlines are constantly changing landscapes that pose fascinating science questions as well as unique management challenges. The National Assessment of Coastal Change Hazards (NACCH) provides robust scientific findings that help to identify areas that are most vulnerable to diverse coastal change hazards including beach and dune erosion, long-term shoreline change, and sea-level rise. Through extensive observation, modeling and prediction of these processes, scientists gauge how U.S. shores have historically shifted, and how past changes will affect their vulnerability to future hazards.
