Learning Focus: How can coastlines be managed through soft engineering? What: Understand the different
types of soft management
How: Explain the advantages and
disadvantages of soft engineering
Why: To enable students to compare
and contrast soft engineering approaches
Connect: The key terms have been scrambled up. Can you unscramble them? • • • • • • • • • •

Extension: Do you remember what each of these mean? Write a definition for each.
Activate: What are the different types of soft engineering? ď‚— Soft engineering works with the
environment whereas hard engineering aims to manage the environment.
Please copy this definitionsinto your book.
ď‚— TASK 1: Complete the worksheet to identify
the different types of soft engineering.
Demonstrate: Sort the following statements into advantages and disadvantages for the two methods Beach Nourishment
Managed Retreat
Cheaper than hard engineering
Inexpensive in the short term
Material can come from off shore dredging which can alter the waves and cause more erosion Protects coastal areas and tourism
People may need to be compensated for loss of land, businesses and homes
Not long lasting – needs replacing each year
Environmentally friendly
Can reduce the impact further down the coast

Management approaches in Minehead and Porlock Watch the video to see how these two areas have tried to manage their coastlines. Consider the positives and negatives of these different approaches
Comparing and contrasting the two schemes
Having watched the video and thought about the advantages and disadvantages, you should give each scheme a score from 1 (poor) to 5 (good), using the same criteria. Add up the total for each scheme. SCHEME Minehead defences
