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.
