To mitigate coastal erosion, the federal government spends an average of $150 million every year on beach nourishment and other shoreline erosion control measures.1 In addition to beach erosion, more than 80,000 acres of coastal wetlands are lost annually—the equivalent of seven football fields disappearing every hour of every day.2 The ...

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.

The problems of shoreline erosion on the North Shore and around Hawaiʻi highlight how vulnerable the state’s communities and economy are to sea level rise and coastal hazards. The growing concern over threats brought by climate change has captured the attention of the public as well as elected officials, spurring a legislative response.

2012年10月30日 · 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.

This online, Spanish-language viewer allows users to visualize changes in Puerto Rico's coastal areas since the year 1930, providing a quick understanding of coastal land cover changes resulting from processes such as natural hazard exposure, modification of natural barriers, coastal erosion, coastal urban development, and others.

2022 Sea Level Rise Technical Report. Released in Februrary 2022, Global and Regional Sea Level Rise Scenarios for the United States, also known as the 2022 Sea Level Rise Technical Report, provides the most up-to-date sea level rise projections available for …

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 ...

This dataset—accessed through the Coastal Change Viewer—shows locations where relatively large areas of land have eroded away or sediment has been deposited between 1972 and 2014. While erosion is typically the greatest concern, areas with high sediment deposition can also create challenges, such as shifting river channels and narrowing ...

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.
