Coastal Change

Coastal change poses potential risk to coastal communities across the nation. Powerful storms generate surge, waves, and currents that can move large amounts of sediment; can destroy roads, buildings, and other critical infrastructure; and can alter natural habitats. The USGS performs a range of studies that document, assess, and model coastal change, risk, and vulnerability. These studies&nb

State of Our Nation's Coast

The USGS Coastal and Marine Hazards and Resources Program (CMHRP) established a Coastal Change Hazards (CCH) programmatic focus to support the optimization of resources, improve the visibility of USGS coastal hazards science, and prioritize science, products, and tools that meet stakeholder needs. Important work by CMHRP scientists and staff within CCH supports hazard mitigation along our nation’s...

Coastal Habitats in Puget Sound

A Pacific Northwest icon, Puget Sound is the second-largest estuary in the United States. Its unique geology, climate, and nutrient-rich waters produce and sustain biologically productive coastal habitats. These same natural characteristics also contribute to a high quality of life that has led to growth in human population and urbanization. This growth has played a role in degrading the Sound...

Sediment Transport in Coastal Environments

Our research goals are to provide the scientific information, knowledge, and tools required to ensure that decisions about land and resource use, management practices, and future development in the coastal zone and adjacent watersheds can be evaluated with a complete understanding of the probable effects on coastal ecosystems and communities, and a full assessment of their vulnerability to natural...

Climate impacts to Arctic coasts

The Arctic region is warming faster than anywhere else in the nation. Understanding the rates and causes of coastal change in Alaska is needed to identify and mitigate hazards that might affect people and animals that call Alaska home.

Remote Sensing Coastal Change

We use remote-sensing technologies—such as aerial photography, satellite imagery, structure-from-motion (SfM) photogrammetry, and lidar (laser-based surveying)—to measure coastal change along U.S. shorelines.

Using Video Imagery to Study Wave Dynamics: Unalakleet

USGS scientists installed two video cameras atop a windmill tower in Unalakleet, Alaska, pointing westward over Norton Sound, to observe and quantify coastal processes such as wave run-up, development of rip channels, bluff erosion, and movement of sandbars and ice floes.

Using Video Imagery to Study Sediment Transport and Wave Dynamics: Nuvuk (Point Barrow)

Two coastal observing video cameras are installed atop a utility pole near the northernmost point of land in the United States, at Nuvuk (Point Barrow), Alaska. The cameras point northwest toward the Arctic Ocean and the boundary between the Chukchi and Beaufort Seas, and will be used to observe and quantify coastal processes such as wave run-up, bluff erosion, movement of sandbars and ice floes...

Using Video Imagery to Study Wave Dynamics: Tres Palmas

Four video cameras look westward over the coast and the coral reef at Tres Palmas in Rincón, on the west coast of Puerto Rico. Two cameras look out at the horizon and over the ocean for the mid-field view; one camera offers a zoomed-in, far-field view overlooking the reef and out to the island of Desecheo, a U.S. National Wildlife Refuge; and another camera focuses on the beach.

Role of Reefs in Coastal Protection

We are combining ocean, engineering, ecologic, social, and economic modeling to provide a high-resolution, rigorous, spatially-explicit valuation of the coastal flood protection benefits provided by coral reefs and the cost effectiveness of reef restoration for enhancing those benefits.

Using Video Imagery to Study Head of the Meadow Beach

Two video cameras are mounted on a bluff near Head of the Meadow Beach, Cape Cod National Seashore, North Truro, MA. One camera looks alongshore toward the north-northeast, and the second looks directly offshore (northeast). The cameras are part of a U.S. Geological Survey research project to study the beach and nearshore environment shared by beachgoers, shorebirds, seals, and sharks. The work is...
