SMP Flashcards
Hold the line
Maintaining the coastal position of the coastline, use hard engineering methods
Advance the line
Extending coastlines out to sea encouraging beach nourishment and groynes
Managed retreat
Allowing coastline to retreat in a managed way
Do nothing
Let nature take its course
Factors considered, economic value and ecological/cultural value of land
Morecambe and Heysham
Along this coastline it has adopted hold the line for the majority
Involves a mix of traditional hard engineering techniques with more contemporary methods to improve potential for sustainable management
Examples
Rock armour/rip rap to enhance and protect existing sea wall
Boulders of limestone were placed along the majority of the existing promenade
Rock groynes were built in front of towns
Beach nourishment in Heysham
Holderness coast
Bridlington popular sea side coast 4.7 km of rock wall and groynes
Hornsea population of 7,500, residential and tourist
Sea wall, rock armour, groynes and beach nourishment
- holderness
Groynes cause further erosion down the coast
SMP for the Holderness have suggested doing nothing in less populated areas caused anger
+ Holderness
Locally have been successful
Erosion now takes place at a much slower pace, villages more protected
Managed retreat
abandoning current line of sea defences
salt marshes develop which reduce wave power
Natural defence to erosion and creates habitat for wildlife
Land is lost and landowners will need to be compensated
