Figure 16. Three models of shoreline response to sea level rise: 

 (a) Erosional response modei/Brunn rule assumes off- 

 shore dispersal of shoreline materials; (b) Island rollover 

 model assumes barrier migrates landward according to 

 rate of sea level rise; (c) Barrier overstepping model 

 assumes submergence in place with barrier remaining on 

 shoreface (after Carter 1988)
