Coast
management
- Soft engineering
- Beach nourishing: sand
transported to repair LSD.
- Strengths: has a
natural look.
- Weaknesses:
costly and may
erode again.
- Strengths: has a
natural look.
- Do nothing: land is no longer
worth defending.
- Strengths: free.
- Weaknesses:
problems could
get worse.
- Strengths: free.
- Red lining or zone
management: preventing
further building on
endangered land.
- Strengths:
saves money
long term.
- Weaknesses:
unpopular and
politically
challenging.
- Strengths:
saves money
long term.
- Beach nourishing: sand
transported to repair LSD.
- Sustainable
management.
- Managed retreat: incentives given
through grants/buyouts to encourage re-
location and ‘set-back’ schemes.
- Strengths: saves
construction costs.
- Weaknesses: difficult to argue and
persuade politically if residents are
involved in the relocation.
- Strengths: saves
construction costs.
- Coastal resilience: allowing flooding and other phenomenons
can have positive ecological outcomes.
- Strengths: very
cost effective and
ecologically helpful.
- Weaknesses: loss of
agriculturally
valuable land can
lead to large scale
losses.
- Strengths: very
cost effective and
ecologically helpful.
- Shoreline management plans:
getting local groups to work
together towards a solution.
- Strengths:
solution
matches specific
needs of the
locals.
- Weaknesses: those
who want
immediate action
can view this as a
delaying tactic.
- Strengths:
solution
matches specific
needs of the
locals.
- Managed retreat: incentives given
through grants/buyouts to encourage re-
location and ‘set-back’ schemes.
- Hard engineering
- Cliff-foot strategies
- Sea walls: a large wall
built to absorb energy
from waves.
- Strenghts: traditional method.
- Weaknesses: very costly
and quite ineffective for
built beaches and LSD
locations
- Strenghts: traditional method.
- Revetments:
a wall that is
built to
reflect wave
energy.
- Strengths: also traditional but
cheaper than sea walls.
- Weaknesses: costly
and ineffective with
very strong waves.
- Strengths: also traditional but
cheaper than sea walls.
- Gabions: wire cages that hold rocks for coastal defences.
- Strenghts: even
cheaper than
revetments.
- Weaknesses: also costly and
only a small scale solution.
- Strenghts: even
cheaper than
revetments.
- Groynes: barricades made
of wood or rock to prevent LSD.
- Strengths: quite
cheap and can be
easily repaired.
- Weaknesses: require maintenance
and can cause more problems
down shore.
- Strengths: quite
cheap and can be
easily repaired.
- Offshore bars: built offshore to
reduce incoming wave strength.
- Strenghts: can be
built out of waste
and mimic nature.
- Weaknesses:
ecological
impacts may not
work that well.
- Strenghts: can be
built out of waste
and mimic nature.
- Rip-rap: large boulders at the shore to
reduce damage to sea walls and shorelines.
- Strenghts: effective for
preventing large scale erosion.
- Weaknesses:
became quite
costly and
may move
with severe
weather.
- Strenghts: effective for
preventing large scale erosion.
- Sea walls: a large wall
built to absorb energy
from waves.
- Cliff face strategies:
- Cliff drainage:
removes water to
prevent landslides.
- Strenghts: cost
effective.
- Weaknesses: dry
cliffs can lead to
collapse.
- Strenghts: cost
effective.
- Cliff regrading: lowering the angle of cliffs to achieve higher ground stability.
- Weaknesses: retreat of cliff
can affect valuable land.
- Strenghts: works on some
types of rocks where
nothing else will.
- Weaknesses: retreat of cliff
can affect valuable land.
- Cliff drainage:
removes water to
prevent landslides.
- Cliff-foot strategies
