Coastal management - Soft engineering

1. Beach nourishment

   • Sand reduces wave energy and maintains tourism
   • Expensive
   • Needs to be replenished constantly as material becomes transported and eroded

2. Managed retreat

   • People and activities move inland
   • Unpopular with local residents
   • Depending on the rate of erosion the movement may have to be more regular

3. Dune regeneration

   • Relatively cheap
   • People resent having to stay out of replanted areas

4. Marsh creation

   • Creates wildlife habitat
   • Farmland destroyed and farmers have to be compensated
