Hard & Soft Engineering Coastal Management Case Studies

Hard Engineering - Coastal Management - Isle of Wight

The Isle of Wight has 65 miles of spectacular coastline, 28 miles of which are designated Heritage Coast. This varied coastline is one of the Island’s main assets.


The Isle of Wight has four coastal defence options:

  1. Hold the Line – retain existing coastline – maintain current deference’s, upgrade or install new ones
  2. Do nothing but monitor – it may not be technically, environmentally or economically possible to do coastal defence work
  3. Retreat the line – this is used to manage the rate and process by which the coast retreats
  4. Advance the line – build new defences seaward, in front of the land, to protect the land behind
