 subsidence (S) is modeled as mm/yr. 



marsh onto adjacent undeveloped lowland late in the simulation period. Overall, however, as 

 expected, a greater net loss of marsh occurs than under the low scenario. 



In North Carolina, particularly in and around Albemarle Sound, the abundant marshes 

 would benefit from sea level rise in the low scenario by spreading onto the extensive low terrace 

 (undeveloped lowland) in the first half of the twenty-first century. Thereafter, however, changes 

 vary more clearly with location. At Manteo, for example, wetlands would be completely lost after 

 the year 2075 as seaward wetlands were inundated and landward wetlands were unable to spread 

 to adjacent lowland. Although the high dunes persist through the year 2100, the wetlands behind 

 them are flooded as are those on the inner edge of the Sound. Only part of this loss can be 

 attributed to a stipulated decline in accretion rate from 5 mm/yr to 2 mm/yr in 2100, because the 

 decline began around 2080 before accretion slowed.
