The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat. It will continue to improve our understanding of processes that control these hazards, and will allow researchers to determine the probability of coastal change locally, regionally, and nationally. The National Assessment will deliver these data and assessment findings about coastal vulnerability to coastal managers, other researchers, and the general public.

| Selected online components of the
National Assessment of Coastal Change Hazards: |
 | National Assessment of Shoreline Change Project
The National Assessment of Shoreline Change Project was initiated to address the need for accurate shoreline change data, including rates and trends that are consistent from one region to another. The completion of the Gulf of Mexico portion of the study marks the first in a series that will eventually address the Atlantic Coast, Pacific Coast, and parts of Hawaii and Alaska. |
 | Coastal Classification Mapping Project
Developing a broad geomorphic coastal classification that, with only minor modification, can be applied to most coastal regions in the United States. Overall objective is to provide accurate representations of pre-storm ground conditions for designated high-priority areas having dense populations or valuable resources that are at potential risk from storm waves. |
 |
Hurricane and Extreme Storm Impact Studies
Investigates the extent and causes of impacts of hurricanes and extreme storms on coastal regions in the United States. Overall objective is to improve the capability to predict coastal change that results from severe tropical and extra-tropical storms. |
 |
National Assessment of Coastal Vulnerability to Sea-Level Rise
Seeks to objectively determine the relative risks due to future sea-level rise for the U.S. Atlantic, Pacific, and Gulf of Mexico coasts. Through the use of a coastal vulnerability index, or CVI, the relative risk that physical changes will occur as sea-level rises is quantified based on the following criteria: tidal range, wave height, coastal slope, shoreline change, geomorphology, and historical rate of relative sea-level rise.
