Three independent teams estimate the erosion that will take place for three scenarios of future sea level rise: 1) current trends of 1 ft per century along the Atlantic coast; 2) the National Academy of Sciences estimate of a 2-1/3 ft global rise in the next century with an 11 inch rise by 2025; 3) the EPA mid-high scenario of a global rise of 4 1/2 ft in the next century and 15 inches by 2025. The quantity of sand necessary to maintain the current shoreline is estimated for each scenario, as are the potential costs of erosion control. -from Authors
