Coastal Management Flashcards
What are the two main objectives of coastal management
Provide defence against flooding
Provide protection against coastal erosion
What is hard engineering
Making physical change to the coastal landscape using resistant materials like concrete, boulders, wood and metal
What is soft engineering
Using natural systems for coastal defence, such as beaches, and salt marshes, which can absorb and adjust wave and tide energy
What are the characteristics of hard engineering
High tech, high cost man made solutions
Sustainability is a key issue, despite initial success
Directly work against nature to reduce erosion
What are the characteristics of soft engineering
Not as effective as hard engineering
Low tech, low cost solutions that work with nature to reduce erosion
More sustainable and considers the environment
What are the different types of hard engineering
Groynes
Sea walls
Rip-rap/ rock armour
Revetments
Gabions
What are the different types of soft engineering
Beach nourishment
Dune stabilisation
Managed retreat
Do nothing
