Coastal Management

Which factors increase coastal erosion

• Strong geology/low wave energy

• High wave energy/ dense populations

• Weak geology/high wave energy

• Sparse populations/Strong geology

Coastal Management is ...

• Varieties of engineering strategies designed to manage coastal erosion

• Varieties of engineering strategies designed to manage coastal deposition

• Engineering strategies designed to control the coastline

• Engineering strategies designed to control people

Which statement accurately describes Hard Engineering?

• Methods of protecting a coastline that promote biodiversity

• A cheaper and more effective way of protecting a coastline

• Significant financial Investment with the building of large scale defences

• Allowing nature to take its course.

Which statement best describes Soft Engineering?

• Sustainable in the long run but needs close inspection and management

• Not at all sustainable and results in fairly ugly changes to the coastline

• Expensive and difficult to produce

• The increased use of concrete contributes to climate change

What are the problems associated with Soft Engineering?

• Expensive and labour intensive

• Increases the utility of the coastline

• Beach Nourishment can be disruptive of wildlife

What are the problems associated with Hard Engineering?

• Makes permanent changes to the environment

• Often effective in its application

• Protects a coast against wave energy

• Can often reduce the aesthetic appearance (more ugly) of a location
