Coastal Erosion | U.S. Climate Resilience Toolkit - NOAA Climate.gov
Coastal Erosion. Coastal erosion is the process by which local sea level rise, strong wave action, and coastal flooding wear down or carry away rocks, soils, and/or sands along the coast. All coastlines are affected by storms and other natural events that cause erosion; the combination of storm surge at high tide with additional effects from ...
Hawai'i Coastal Erosion Website | U.S. Climate Resilience Toolkit
Tools. Hawai'i Coastal Erosion Website. Shorelines are highly variable environments characterized by a number of natural hazards, including tsunami, storm surge, high winds, coastal erosion, sea level rise, and high-wave overtopping. Building on eroding coasts increases vulnerability to all these hazards. A direct step to mitigating the impact ...
Confronting Shoreline Erosion on O‘ahu
Intense waves and high sea level events contribute to coastal erosion, which threatened this house on the North Shore of O‘ahu. Over the winter of 2013–2014, however, the ocean swells threatened disaster. The pounding waves and high tides caused severe erosion and loss of land in front of about 20 homes along Sunset Beach.
Building Resilience in Coastal Communities
Economic activity in coastal counties accounted for approximately 66 million jobs and $3.4 trillion in wages through diverse industries and commerce in 2010. 1 That year, about $6.4 trillion, or 45 percent of the nation’s gross domestic product, was generated by coastal communities. Roughly half of our nation’s vulnerable property value is ...
Coasts | U.S. Climate Resilience Toolkit - NOAA Climate.gov
Restoring and conserving coastal ecosystems and adopting natural and nature-based infrastructure solutions can enhance community and ecosystem resilience to climate change. As the pace and extent of coastal flooding and erosion accelerate, the impacts of climate change exacerbate existing social inequities.
Storm Surge | U.S. Climate Resilience Toolkit - NOAA Climate.gov
Oct 30, 2012 · Additional impacts of storm surge include extensive property loss, erosion of beaches, damage to coastal habitats, and undermining the foundations of infrastructure such as roads, railroads, bridges, buildings, and pipelines. Storm surges also pose a serious threat of death by drowning. Storm surge damage caused by Hurricane Ike in Texas during ...
Sea Level Rise | U.S. Climate Resilience Toolkit - NOAA Climate.gov
At the global scale, sea level is rising, and its pace has quickened. Measured at tide gauges on every continent and by satellites from space, global average sea level rose about 10-12 inches over the last 100 years (1920-2020). Now, oceanographers expect an additional 10-12 inches of global sea level rise in the next 30 years (2020-2050). 1.
Coastal Erosion on Cape Halkett, Alaska | U.S. Climate Resilience …
Coastal Erosion on Cape Halkett, Alaska. Thawing permafrost causes coastline collapse on Alaska's North Slope, which is no longer kept frozen and protected from fall storms by sea ice—the ice now forms later in the season. The Alaska Native Tribal Health Consortium helps communities assess options to address coastal erosion and other climate ...
Arctic Oceans, Sea Ice, and Coasts | U.S. Climate Resilience Toolkit
The loss of sea ice in the Arctic also exposes shorelines to rapid coastal erosion. For most of the year, landfast sea ice has buffered Alaska's northern coastline from waves, winds, and currents. Current observations and future projections show that as sea ice melts earlier and forms later in the year, Arctic coasts will be more vulnerable to ...
Relocating Kivalina | U.S. Climate Resilience Toolkit
In 2000, the community settled on a nearby—and potentially safer—site for relocation, dubbed Kiniktuuraq. However, investigations by the U.S. Army Corps of Engineers determined that Kiniktuuraq could also fall victim to climate change impacts over time. Thus, the search for a new home for Kivalina residents continues.
