Commercial, residential and industrial uses.
Flooding threatens these uses.
When was coastal management beginning to become popular?
End of 19th century.
Why does erosion cause conflict with human activity?
People think the coastline is static rather than a dynamic system.
Why are coastal defence measures needed along the coastline?

What do SMPS provide?
A sound basis for the provision of coastal protection.
What did a study show in 1991
The link between coastal managment provision in one area with effects on adjoining areas.
What has happened today in England Wales?
TODAY.
11 sediment cells.
46 sub cells exist.
How are SMPS developed?
By groups from adjoining areas including planners, engineers and geomorphologists.
What does coastal management mean?
Controlling development and change in coastal zone and undertaking work according to agreed principles and criteria.
What does good managment mean?
Involving both physical and environmental considerations as well as views from residents and groups.
Balanced policy.
Name the 3 stages in managment?
1 understand cause of problem.
2 Undertake works to reduce/solve problem.
3 Improve protection.
What 2 aims does coastal management have?
Provide defence against flooding and erosion.
Name other aims?
Stabilisation beaches affected by LSD.
Stabilising sand dunes.
Protecting salt marshes.
What does hard engineering do?
Works against nature and aims to resist the energy of waves and tides through significant human investment.
Expensive to build/maintain.
Negative effects from hard engineering.
Narrower shorelines.
Reduce habitats.
Effect sediment movement.
Not keep pace with rise in sea levels.
