Welcome to the U.S. Geological Survey's Coastal Change Hazards (CCH) portal, where you have interactive access to coastal change science and data for our Nation’s coasts. The CCH portal is a collaborative project between USGS Coastal and Marine Geology Program (CMGP) scientists and informatics specialists and software engineers at the USGS Center for Integrated Data Analytics (CIDA).
This page provides background on the portal, and a summary of how to use its basic functions. We encourage you to explore and learn. If you see changes needed or have ideas for improving the access and use of this USGS data and information, please email firstname.lastname@example.org.Portal Functionality
The Coastal Change Hazards portal organizes products and information into discrete items within three specific coastal hazard themes: 1) severe storms, 2) shoreline change, and 3) sea-level rise. Each data item represents an individual research product. Items with a common topic area are grouped into aggregations within a theme, to show the breadth of that topic and make it easy to explore related information. Items and aggregations can be added to a bucket that saves this information for download or sharing. See video below to view a short tutorial on how to find and share data.

Our Nation’s coastlines are constantly changing landscapes that pose unique management challenges. Robust scientific findings help identify areas that are most vulnerable to diverse coastal change hazards including beach and dune erosion, long-term shoreline change, and sea-level rise. The data, models, and tools available through the CCH portal can be used by federal and state agencies, non-governmental organizations, municipal entities, and private citizens. Here are some examples:
- Coastal hazards information is used by planners and emergency managers as they work to protect resources, reduce risk, and prevent economic losses. Storm, shoreline change, and sea-level rise vulnerability assessments can improve understanding of the diversity and nature of specific coastal hazards. Our updated assessments describe how vulnerability has changed over time and inform plans for the future. This information can be viewed, downloaded, and shared. Web data services provided through the CCH portal allow USGS data to be incorporated into custom applications by other agencies, organizations, and private industry.
- Coastal residents can visualize hazards in their area, download or print information, and share information with others through social media.
- Emergency first-responders can access the most current, near-real-time updates of storm impact probabilities (collision, overwash, inundation), so they have current information in order to direct appropriate staging of response personnel and equipment.
The products provided through the CCH portal fulfill critical immediate and ongoing needs for scientifically credible and actionable information to increase resilience to storms and climate change. This information can support land use planning, infrastructure, ecosystem and cultural resource management decisions, as well as storm response and recovery. The explicit goal of the project is to enable users to apply and integrate the data and tools to address their specific needs.
