Natural processes such as waves, tides, and weather, continually change coastal landscapes. The integrity of coastal homes, businesses, and infrastructure can be threatened by hazards associated with event-driven changes, such as extreme storms and their impacts on beach and dune erosion, or longer-term, cumulative changes associated with coastal and marine processes, such as sea-level rise. Scientists working on Coastal Change Hazards conduct basic and applied research and provide relevant science-based products to assist the Nation with these coastal change hazard challenges. By building a community with a broad range of expertise, CCH facilitates the integration of diverse coastal science and the exchange of new ideas and approaches across the Coastal and Marine Hazards and Resources Program (CMHRP). Innovative collaboration is encouraged in order to identify and address the Nation’s needs and coastal change hazards problems. Through observation and modeling, CCH develops robust and accessible coastal change assessments that help improve the lives, property, and economic prosperity of the Nation’s coastal communities, habitats, and natural resources.

CCH is a program focus led and executed by a community of USGS scientists, technicians, and communicators working together to develop advanced capabilities to observe, understand, and forecast changes to the Nation’s coast with immediate and long-term applications. By building a community with a broad range of expertise, CCH facilitates the integration of diverse coastal science and the exchange of new ideas and approaches across the Coastal and Marine Hazards and Resources Program (CMHRP). CCH encourages innovative collaboration in order to identify and address the Nation’s coastal change hazards problems.
Recognizing the full scope of activities needed to produce science products that address national needs, CCH is organized into three complementary components:
Stakeholder Engagement and Communication (SEC) is focused on connecting CCH science to stakeholders both within USGS and external to the agency. SEC initiates open conversations with these stakeholders to learn more about their needs for data, tools, and information. This helps to ensure that CCH science meets the needs of the Nation, and the science and data are useful and accessible.
Technical Capabilities and Applications (TCA) provides and applies technical expertise, methods and data visualizations to sustain regional to national-scale CCH assessment products; manages CCH data sharing and visualization efforts; and coordinates a Program-wide technical community that serves as a resource for projects across CMHRP.
Research advances the science that supports the products users rely on to inform decision making. CCH integrates research across the three Coastal and Marine Science Centers and aligns basic and applied research directions with CCH user-informed science priorities.
The result of close coordination and collaboration between SEC, TCA, and Research is a CCH program focus that aims to:
- Build a CCH community, with a broad range of expertise and disciplines, that shares data, methods, and practices to address complex science questions and community needs;
- Produce societally-relevant basic and applied science addressing coastal change hazards;
- Develop and provide science-based products that can be used by stakeholders to address coastal change hazard issues across the Nation; and
- Engage stakeholders and incorporate user needs into science planning deliverables.

Coastal Change in Alaska
Alaska's north coast has been home to indigenous communities for centuries. Changing coastlines threaten important infrastructure and historic sites that support indigenous communities. Changing coastlines also can potentially reduce habitat for Arctic wildlife, such as polar bears, shorebirds, and walruses.

The Role of U.S. Coral Reefs in Coastal Protection
U.S. Geological Survey scientists have shown that along with providing food, tourism, and biodiversity, coral reefs also protect dollars and lives. This interactive geonarrative introduces the USGS research to understand the role of US coral reefs in coastal protection.
National Shoreline Change
Exploring Shoreline Positions of the United States From the 1800s To The Present. This geonarrative explains how the USGS derives shorelines from various data sources, and how shoreline change rates are generated from these data. The Natural Hazards Mission Area programs of the USGS develop and apply hazard science to help protect the safety, security, and economic well-being of the Nation.
Barrier Islands
U.S. Geological Survey Researchers Monitor Barrier Islands. This geonarrative features research used to monitor Barrier islands which are narrow stretches of sand deposited parallel to the shoreline, are inherently valuable ecosystems. They protect estuaries and lagoons that help reduce coastal erosion, purify the water, and provide habitat for fish and birds.

The likely impact of Hurricane Florence on sandy shorelines of the US East Coast is provided three days prior to landfall. The bands on the map represent different coastal change hazards concerning beach dunes. Outer band: Dune erosion. Middle band: Dune overwash. Inner band: Dune inundation, with potential flooding behind the dune. Credit: USGS Coastal Change Hazard Portal.

At Fire Island, New York estuarine, wetland, coastal, and oceanic processes interact, affecting natural habitats and coastal communities. The CMHRP conducts scientific investigations at Fire Island in order to protect coastal infrastructure. The USGS conducts seasonal surveys along the west coast each year, to monitor how beaches are changing through time. Here, a USGS scientist navigates a personal watercraft equipped with GPS and sonar to measure seafloor depths near the beach. The GPS system enables the driver to follow a precise path and to revisit the same path in future surveys. The result of close coordination and collaboration between SEC, TCA, and Research is a CCH program focus that aims to:
- Build a CCH community, with a broad range of expertise and disciplines, that shares data, methods, and practices to address complex science questions and community needs;
- Produce societally-relevant basic and applied science addressing coastal change hazards;
- Develop and provide science-based products that can be used by stakeholders to address coastal change hazard issues across the Nation; and
