DESCRIPTION
Coasts seven
Citation preview
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? • tiattron • igoanbs • yadlihruc ioncat • ocrosniro • ofst eeriiengnng • ocasrionr • boraasin • ahrd ngineeengri • ase allw • esgroyn Extension: Do you remember what each of
these mean? Write a definition for each.
Activate: What are the different types of soft engineering?
Soft engineering works with the environment whereas hard engineering aims to manage the environment.
Please copy this definitionsinto your book.
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
People may need to be compensated for loss of land, businesses and homes
Protects coastal areas and tourism
Can reduce the impact further down the coast
Not long lasting – needs replacing each year
Environmentally friendly

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
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.
