It is a much broader term than coastal erosion because land loss also ...
Coastal erosion has been increasing over the past few years, and it is still on the rise, making it a major coastline hazard. In the United States, 45 percent of the coastline is along the Atlantic or Gulf coast, and the erosion rate per year along the Gulf coast is currently at six feet a year.
