Summary 

  The National Coastal Erosion Risk Management (NCERM) map shows the spatial NCERM coastal baseline. This baseline is split to 'frontages'. These are defined as lengths of coast with consistent characteristics based on the cliff behaviour characteristics and the defence characteristics. It is intended as an up-to-date and reliable benchmark dataset showing erosion extents and rates for three periods from a base date of 2005:
  • Short Term (0 - 20yr i.e. 2005 to 2025);
  • Medium Term (20 - 50yr i.e. 2025 to 2055); and
  • Long Term (50 - 100yr i.e. 2055 to 2105). The data extents are based on 50%ile confidence levels, whilst the data attributes highlight the 5-95%ile confidence range, of erosion predictions for the following two scenarios (NB All distances are cumulative over time and given in metres):
  • No Active Intervention Policy Scenario; and
  • With the implementation of Shoreline Management Plan 2 Policies. Defence type and SMP policies for each of the three periods described above are included.
