Coastline management

• What are the 4 main approaches to shoreline management plans?

  Do nothing - carry out no coastal defences except safety measures

  Hold the line - use sea defences to stop erosion, the coast stays where it is today

  Advance the line - move the existing defence seaward

  Retreat the line - gradually let the coast erode, and move businesses and people away from areas at risk
• Why are some places not protected from flooding?

  The value of the land and buildings may not justify the cost of protection

  Building defences might cause more erosion elsewhere

  Climate change is likely to bring rising sea levels
