coastal management

• no active intervention


  no intervention in defending against flooding or erosion whether or not coastal defences have existed previously
• hold the line


  build or maintain coastal defences so that the position of the shoreline remains the same overtime - soft or hard engineering
• managed retreat/realignment


  moving the line of defence further inland - actively removing the coastal defences to allow areas to flood
• advance the line


  build new defences on the seaward side of current defences - land reclamation
