  15. 15. ready?
  16. 16. 1) Stabalising coastaldunes
  17. 17. what are coastal dunes? these are coastal dunes - huge piles of sand at the coast
  18. 18. how huge?You see this group of people over here?
  19. 19. coastal dunes are formed naturally in some coasts
  20. 20. coastal areas costal dune behind the coastal dunesea
  21. 21. coastal areas If a huge wave costal dune behind thewere to approach coastal dune the coast sea
  22. 22. What can coastal dunes do to the coastal areas If a huge wave costal dune behind thewere to approach coastal dune the coast sea
  23. 23. thus people see the value ofcoastal dunes as a form ofprotection
  24. 24. They grow vegetation on it so that the roots can trapthe sand and stop the dunes from moving. Hencestabilising the coastal dunes.
  25. 25. END OFCOASTAL DUNESdeal with pg 22-23 ofyour notes.
  26. 26. 2) Planting ofmangroves
  27. 27. These are mangrove treesWhat do you notice about its roots?
  28. 28. What do you notice about its roots?
  29. 29. What do you notice about its roots?
  30. 30. What happens whenwaves pass through the roots?
  31. 31. Banda Aceh, 2004, before tsunami Mangrove Forest Mangrove Forest removed Mangrove Forest Mangrove Mangrove Forest Forest removed
  32. 32. Banda Aceh, 2004, After the tsunami Mangrove Forest Mangrove Forest removed Mangrove Forest Mangrove Mangrove Forest Forest removed
  33. 33. END OFPLANTING OFMANGROVESdeal with pg 24-25 ofyour notes.
  34. 34. 3) Beach Nourishment Adding of materials to make the beach bigger
  35. 35. ch b ea nal igior

  41. 41. M iami ach , USABe 1970s No beach!
  42. 42. M iami ach , USABe 1970s No beach! After beach nourishment, Hey there’s a beach
  43. 43. END OFBEACHNOURISHMENTdeal with pg 26-27 ofyour notes.
  44. 44. 4) Encouraging growthof coral reefs
  45. 45. What are coral reefs?let’s go under the sea!
  46. 46. Corals : small living organisms Coral reefs : Huge stone-like structurescreated by corals for them to live in
  47. 47. More coral reefs
  48. 48. How big are coral reefs
  49. 49. Coral Reefs
  50. 50. Coral Reefs Coral Reefs
  51. 51. What did coral reefs do to the depth of the sea?
  52. 52. island before coral reefs island sea sea floor
  53. 53. island after coral reefs islandcoral reefs coral reefs sea sea floor
  54. 54. island after coral reefs What will coral reefs do to a wave island approaching the island?coral reefs coral reefs sea sea floor
  55. 55. you see what coral reefs does to the depth of the sea? Coral Reefs
  56. 56. As you can see, coral reefs have a lot of benefits. So some countries tries to encourage its growth.Corals require a certain base to build reefs and start growing. So some engineersencourage the growth of corals by adding structures onto the sea floors.
  57. 57. CoralsMetal Structure
  58. 58. Bricks
  59. 59. Even old ships are sunk to encourage the growth of corals! Railing for the front of the ship
  60. 60. END OFENCOURAGING THEGROWTH OF CORALREEFS deal with pg 28-29 of your notes.
