Justin J. Birchler, Hilary F. Stockdon, Kara S. Doran, David M. Thompson
2014, Open-File Report 2014-1243
Beaches serve as a natural buffer between the ocean and inland communities, ecosystems, and natural resources. However, these dynamic environments move and change in response to winds, waves, and currents. During extreme storms, changes to beaches can be great, and the results are sometimes catastrophic. Lives may be lost, communities...
