  • Building a sea wall
  • Building groins
  • Rock armor and boulder barriers
• What is the purpose of a sea wall?

  To protect cliffs, land, and buildings
• What is a disadvantage of curved sea walls?

  They reflect wave energy back to the sea
• What are groins and their purpose?

  Wooden barriers preventing beach material movement
• How do groins affect beach material?

  They allow the buildup of a beach
• What is rock armor?

  Large boulders piled on the beach
• What is the main advantage of rock armor?

• What is beach nourishment?

  Replacing beach or cliff material lost to erosion
• What is a key advantage of beach nourishment?

  It provides natural defense against erosion
• What is managed retreat?

  Allowing areas to erode and flood naturally
• What is a benefit of managed retreat?

  Encourages development of natural defenses
• What is a disadvantage of managed retreat?

  People need compensation for lost property
• What are the environmental benefits of managed retreat?

  • Development of beaches
  • Creation of salt marshes
