soft engineering

Question 1

what is soft engineering?

Answer 1

managing erosion by working with natural processes to help restore beaches/ecosystem and resuce erosion.

Question 2

what are the 3 soft engineering strategies?

Answer 2

beach nourishment, reprofiling and dune regeneration.

Question 3

what is beach nourishment?

Answer 3

the addition of new material to a beach to make it wider.

Question 4

what are some positives and negatives of beach nourishment?

Answer 4

positives
-relatively cheap.
-increases tourism.
negatives
-needs replenishing regularly.
-groynes useful to keep the material in place.

Question 5

what is reprofiling?

Answer 5

the redistribution of sediment from the lower section of the beach to the high section (increases gradient).

Question 6

what are some positives and negatives of reprofiling?

Answer 6

positives
-theyre cheap.
-reduces wave energy/erosion.
negative
-only works when wave energy is low.
-needs to be redone regularly.

Question 7

what is dune regeneration?

Answer 7

the action taken to build up dunes and increase vegetation on them, includes planting marram grsss fencing and boardwalks.

Question 8

what are some positives and negatives of dune regeneration?

Answer 8

positives
-its quite cheap.
-maintains a coastal habitat.
negatives
-takes a long time.
-can hinder tourism.

Question 9

what are some positives and negatives of soft engineering?

Answer 9

positives
-is cheaper in the short term.
-more sustainable.
-looks more natural.
negatives
-needs more maintenance.
-not as effective at reducing erosion.
