National Assessment of Coastal Change Hazards Active
Research to identify areas that are most vulnerable to coastal change hazards including beach and dune erosion, long-term shoreline change, and sea-level rise.
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.
Storm-Induced Coastal Change Hazards - Research to understand the magnitude and variability of extreme storm impacts on sandy beaches in order to improve real-time and scenario-based predictions of coastal change to support management of coastal infrastructure, resources, and safety.
Long-Term Coastal Change - Nationally-consistent compilation of historic shoreline positions and maps of changes along open-ocean sandy shores of the conterminous U.S. and parts of Alaska and Hawaii.
Coastal Vulnerability to Sea-Level Rise - Historical and recent observations of coastal change are combined with model simulations of beaches, barrier islands, wetlands, and coastal aquifers to determine the probability of coastal change due to sea-level rise.
Coastal Change Hazards Portal - Online access to data and tools enables users to apply coastal change hazards assessments to their specific needs.
Integration of Processes over Different Spatial and Temporal Scales - Integration of the different scales of coastal processes to better understand future vulnerability to storms, long-term erosion, and sea-level rise.

The Coastal and Marine Geology Program of the U.S. Geological Survey has generated a comprehensive database of digital vector shorelines and shoreline change rates for the U.S. Southeast Atlantic Coast (Florida, Georgia, South Carolina, North Carolina). These data, which are presented herein, were compiled as part of the U.S. Geological Survey's National Assessment of Shoreline Change Project. BeaAuthorsTara L. Miller, Robert A. Morton, Asbury H.

MooreCoastal vulnerability to sea-level rise: a preliminary database for the U.S. Atlantic, Pacific, and Gulf of Mexico coasts
The prediction of coastal evolution is not straightforward. There is no standard methodology, and even the kind of data required to make such predictions are the subject of much scientific debate. Since a viable, quantitative predictive model for coastal evolution is not available. The relative susceptibility of the Nation's coastline to sea-level rise is quantified here at a regional to nationalAuthorsErika S. Hammar-Klose, E.

A new scale is proposed that categorizes impacts to natural barrier islands resulting from tropical and extra-tropical storms. The proposed scale is fundamentally different than existing storm-related scales in that the coupling between forcing processes and the geometry of the coast is explicitly included. Four regimes, representing different levels of impact, are defined. Within each regime, patAuthorsA. H.
