The National Coastal Change Assessment (NCCA) aims to establish historic coastal change by extracting the georectified coastline position from OS 2nd Edition Country Series maps (1892-1905) and to then compare it to both the 1970s and current coastal position (updated by LiDAR datasets where available) in order to estimate past erosion/accretion rates.
\r\n\r\nUsing the historic coastal change rates the coastline position can then be projected into the future, albeit mediated by a Coastal Erosion Susceptibility Model (CESM) whose function is to limit erosion to areas where the hinterland is susceptible to erosion.
