This document provides instructions for a makeup lesson on soft engineering coastal management strategies. It explains that students will review their notes and learn about different strategies one by one from slides. For each strategy, students will either be given the reaction and come up with the outcome, or vice versa, or come up with both if neither is provided. The strategies covered include stabilizing coastal dunes by planting vegetation, planting mangroves to reduce wave energy, beach nourishment to widen beaches, and encouraging coral reef growth by adding structures for corals to grow on.

7. how does this lesson
work?
1) Refer to your notes
2) You are given the reaction or outcome
for what’s relevant.
3) The slides will tell you more about the
coastal management strategies one at a
time.
4) You will be given more information
about each strategy.

8. how does this lesson
work?
5) At the end of each strategy, you will need to look at your
notes. and use the information you got from the slides.

17. 1) Stabalising coastal
dunes

18. what are coastal dunes?
these are coastal dunes
- huge piles of sand at
the coast

19. how huge?
You see this group of
people over here?

21. coastal dunes are formed
naturally in some coasts

22. coastal areas

24. What can coastal dunes
do to the
coastal areas
If a huge wave costal dune behind the
were to approach coastal dune
the coast
sea

26. thus people see the value of
coastal dunes as a form of
protection

28. They grow vegetation on it
so that the roots can trap
the sand and stop the dunes
from moving. Hence
stabilising the coastal dunes.

50. 4) Encouraging growth
of coral reefs

51. What are coral reefs?
let’s go under the sea!

52. Corals : small living organisms
Coral reefs :
Huge stone-like
structures
created by corals
for them to live
in

53. More coral reefs

63. you see what coral reefs does to the depth of the sea?
Coral Reefs

64. 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 engineers
encourage the growth of corals by adding
structures onto the sea floors.

to encourage the
growth of corals! Railing for the front of
