Photo shows results of wave-driven flooding and overwash on Roi-Namur Atoll, Republic of the Marshall Islands.

Diagram of different ocean features that contribute to coastal flooding.

Hill-shaded bathymetric, backscatter, and photographic data collected by NOAA and the USGS. Backscatter data give indications of seafloor character. In general, low-backscatter intensity (blue) corresponds to finer-grained material, whereas high-backscatter intensity (orange) corresponds to coarser substrate.

The USGS conducted surveys on the inner continental shelf of the Delmarva Peninsula (shown in green) to complement related datasets previously collected in the area by partners NOAA and BOEM. The inset map shows location of the study area.

Installing large boulders as riprap to armor the shore against further erosion at Goleta Beach in Southern California. The tide is very low (negative).

USGS scientist Zafer Defne measures water and sediment movement at Forsythe National Wildlife Refuge, New Jersey. Defne is co-author with Neil Ganju of a 2017 study on how to estimate coastal salt marshes’ potential longevity, based on their sediment budgets and the ratio of open water to vegetation.
