Geo Hard And Soft Engineering

Question 1

What is hard engineering in coastal protection?

Answer 1

Hard engineering refers to the use of solid structures to control natural processes and protect coastlines.

Question 2

True or False: Soft engineering is a more environmentally friendly approach to coastal management.

Answer 2

True

Question 3

Fill in the blank: __________ are structures built to absorb wave energy and reduce erosion.

Answer 3

Breakwaters

Question 4

What is the primary goal of coastal protection?

Answer 4

The primary goal is to protect coastal areas from erosion and flooding.

Question 5

Which of the following is NOT a method of hard engineering? A) Sea walls B) Groynes C) Beach nourishment

Answer 5

C) Beach nourishment

Question 6

What are groynes used for?

Answer 6

Groynes are used to trap sediment and prevent beach erosion.

Question 7

True or False: Beach nourishment is a method of hard engineering.

Answer 7

False

Question 8

What is a disadvantage of hard engineering methods?

Answer 8

They can be expensive and may have negative environmental impacts.

Question 9

Define ‘soft engineering’.

Answer 9

Soft engineering involves using natural processes and materials to manage coastal erosion and flooding.

Question 10

Fill in the blank: __________ involves adding sand to beaches to combat erosion.

Answer 10

Beach nourishment

Question 11

What is the function of sea walls?

Answer 11

Sea walls are designed to protect the coast from wave action.

Question 12

Which of the following is a soft engineering technique? A) Rock armor B) Managed retreat C) Sea wall

Answer 12

B) Managed retreat

Question 13

What is managed retreat?

Answer 13

Managed retreat is a strategy where coastal communities allow certain areas to flood and relocate infrastructure to safer locations.

Question 14

True or False: Hard engineering solutions require regular maintenance.

Answer 14

True

Question 15

What is the purpose of a revetment?

Answer 15

Revetments are used to protect the base of a structure from erosion by dissipating wave energy.

Question 16

Fill in the blank: __________ is a process that involves planting vegetation to stabilize sand dunes.

Answer 16

Dune stabilization

Question 17

What is a major environmental concern of hard engineering?

Answer 17

Hard engineering can disrupt natural sediment transport and harm marine ecosystems.

Question 18

List one advantage of soft engineering.

Answer 18

Soft engineering is typically more sustainable and environmentally friendly.

Question 19

True or False: Hard engineering solutions can lead to increased erosion in adjacent areas.

Answer 19

True

Question 20

What is a common material used in rock armor?

Answer 20

Boulders or large rocks are commonly used in rock armor.

Question 21

What is the role of coastal vegetation in soft engineering?

Answer 21

Coastal vegetation helps to stabilize soil and reduce erosion.

Question 22

Fill in the blank: __________ are barriers built out into the water to protect the shore.

Answer 22

Breakwaters

Question 23

What does the term ‘coastal squeeze’ refer to?

Answer 23

Coastal squeeze refers to the loss of intertidal habitats due to rising sea levels and hard engineering structures.

Question 24

Name one example of hard engineering.

Answer 24

Sea wall
