Coastal Change Hazards Portal
The Coastal Change Hazards Portal, created by the U.S. Geological Survey (USGS), allows anyone to interactively “see” past, present and future hazards. It provides interactive, mobile access to coastal change science and data for the nation’s coasts. The tool fulfills critical immediate and ongoing needs for scientifically credible and actionable information to increase resilience to storms and climate change. This information can support emergency preparedness, ecocystem restoration, and where and how to develop coastal areas.
No sophisticated technology is required. The tool runs on web browsers, tablets, and smartphones. It is designed for a wide-range of audiences, from federal and state agencies to non-governmental organizations, public entities, and private citizens. One key component of the portal is the ability to explore coastal hazard risks at varied scales, from a local area of interest to a national perspective. This location-specific capability is extremely valuable for planning and preparedness and for making decisions to build coastal resilience.
A range of information is provided through the portal, such as historical data, existing publications, satellite imagery, maps, and more. This "mashup" of information is possible due to the wide scope of USGS expertise. For example, USGS scientists have completed a national research project that measures and interprets coastline change from the past 150-plus years. By looking to the past, scientists have direct evidence of how our diverse shorelines have behaved, allowing for more accurate analyses of future change. The USGS also investigates coastal change during extreme storms to help understand hazards such as severe beach erosion, island overwash, or coastal inundation. The portal will enable users to view USGS science in conjunction with their own personalized data to answer specific questions.
