geography coastal management

what are some examples of land uses in coastal areas
tourism, industry, fishing, trade and transport
1 of 42
what different groups of people who have an interest in how coastal areas are managed
local residents, environmental groups, developers, local councils, national governments, tourist companies, national parks authorities
2 of 42
what is an interest group
groups of people who have a common interest in an issue or problem
3 of 42
a difference of opinion in interest groups may cause what
it may cause conflict between interest groups
4 of 42
reasons why groups of people might be concerned about the coast
erosion may be threatening beaches or coastal settlements; people may want to develop tourism in an area, or existing tourism could be declining;there is a danger of looking is seas levels rise; there could be problem with sewage and or pollution
5 of 42
physical management of the coast attempts to control natural processes such as what
such as erosion and longshore drift
6 of 42
what is hard engineering
hard engineering is generally defined as controlled disruption of natural processes by using man-made structures.
7 of 42
what is soft engineering
soft engineering is the use of ecological principles and practices to reduce erosion and achieve the stabilization and safety of shorelines
8 of 42
which type of coastal engineering is more expensive
hard engineering
9 of 42
which type of coastal engineering is short term
hard engineering
10 of 42
which type of coastal engineering is long term
soft engineering
11 of 42
give 3 examples of hard engineering options
building a sea wall, building groynes, rack armour/boulder barriers
12 of 42
what is a sea wall
a wall built at the edge of the coastline
13 of 42
what are the advantages of building a sea wall
protects the base of cliffs, land and building against erosion, can prevent coastal erosion in some areas
14 of 42
what are the disadvantages of building a sea wall
expensive to build, and curved sea wall reflect the energy of the waves back to the sea (this means the wave remains powerful) and as a result the sea wall may erode, also the cost of maintenance is high
15 of 42
what is a sea groyne
a wooden barrier built at right angles to the beach
16 of 42
what are the advantages of building groynes
prevents the movement of beach material long the coast by longshore drift, allows the build up of a beach, and beaches are unnatural defence against erosion an
17 of 42
what is the disadvantage of building groynes
can be seen as unattractive, costly to build and maintain
18 of 42
what are rock armour/boulder barriers
large boulders/rocks piled up on the beach
19 of 42
what are the advantages of rack armour/boulder barriers
absorb the energy of waves, allows the build up of a beach
20 of 42
what are the disadvantages of rock armour/boulder barriers
can be expensive to obtain and transport the boulders
21 of 42
which engineering option is more sustainable
soft engineering
22 of 42
what are the 2 main types of soft engineering
beach nourishment, and managed retreat
23 of 42
what is beach nourishment
this replaces beach or cliff material that has been removed by erosion or longshore drift
24 of 42
what are the 2 main advantages of of beach nourishment
beaches are a natural defence against erosion and coastal flooding, and relatively inexpensive
25 of 42
what do beaches attract
tourists
26 of 42
what is a disadvantage of beach nourishment
requires constant maintenance to replace the beach material as it is washed away
27 of 42
what is managed retreat
when areas of the coast are allowed to erode and flood naturally
28 of 42
what management process is most sustainable in areas of low value land
managed retreat
29 of 42
what are the advantages of managed retreat
it encourages the development of beaches and salt marshes; and cost is low/and a cheap option
30 of 42
what are the disadvantages of managed retreat
people will still need to be compensated for the loss of buildings and farmland
31 of 42
name a place you have studied, which is an example of coastal management
holderness coast
32 of 42
where is holders, and why is it such an infamous coastline
it is in the north east of England; this is one of the most vulnerable coastlines in the world
33 of 42
at what rate does this holderness coast retreat at
at a rate of one to tow metres every year
34 of 42
what causes the holders coastline to retreat
strong prevailing winds creating longshore drift that moves material south along the coastline; the cliffs are made of a soft boulder clay and will therefore erode quickly, especially when saturated
35 of 42
what 2 engineering options have been taken to protect holderness
rock armour, building two rock groynes
36 of 42
as a result of the protection, what condition are the cliffs in now
the cliffs are no longer at great risk of erosion
37 of 42
what have the rock groynes stopped
it has stopped beach material being moved south from mappleton along the coast
38 of 42
what is the negative consequence of protecting the north holders coast of mappleton
this has increased erosion south of mappleton
39 of 42
overall how can this be explained
benefits in one area might have a negative effect on another
40 of 42
the increased threat of sea levels rising is due to what
climate change
41 of 42
this will mean the places will have to consider what
they will have to consider the sustainability of coastal defence strategies for the future
