Coastal Management refers to the use and protection of Australia’s coastline and surrounding areas,
which is made up of marine and estuarine ecosystems
Geographic Processes
Beach Formation
Nature of the Coastal Zone
1. Erosional Processes
2. Depositional Processes
Constructive Waves
Destructive Waves
3. Longshore Drift
Dune Formation
Human Impact in Coastal Regions
Housing & Development
Construction
of houses
Removal of
vegetation
Disruption of natural processes
Ports & Marinas
Stone- breakwaters constructed to
reduce the impact of waves and
tidal fluctuations
Hinders natural erosion & mineral
deposition processes
Stormwater run-off
& Pollution
Vast areas of concrete land & bitumen roads
generate significant amounts of contaminated
stormwater run-off
Become pollutants & contaminants
Recreation & Tourism
Management Strategies
Why is there a need to
manage coastal areas?
Polluted coastal waters can:
Cause decline in marine species
Become affected by
litter & debris
Become affected by
household & industrial
rubbish
Dealing with Coastal Pollution
Coastal Catchements Initiative
(CCI)
Protects water quality by
reducing sedimentation
Discharges of polluted water
in coastal waters
Permits are required from the
Department of Environment, Water,
Heritage and Arts for activities that
may put coastal areas at risk
Integrated Coastal Zone Management (ICZM)
Maintains and restores
coastal zone ecosystems
Involves the coordination of individuals,
groups and governments in maintain the
quality of coastal environments
Clean Up Australia Day
Who manages the coast?
All levels of government
have some responsibility
International agreements
Different perspectives
Opinions can be expressed by stakeholders
Local residents, shopkeepers, scientists, conservationists, developers
Environment Impact Statement
must be prepared before govt.
approval
EIS shows the likely impact of a development
on a phyical environment
