86% of Australians live along the coast. Yet recent stressors and challenges of degradation
have been raised as natural processes in coastal zones are altered by high energy events such
as sea level rise. Which have caused loss of the coastal ecosystems, particularly within coastal
wetland which are the most sensitive and response-able coastal ecosystem of any pressures.
Modelling modifications to natural processes is important. Thus, Comerong Island (Southeast
NSW) represents an ideal example of this context that reflecting disturbance regimes.
The measurable parameters of multi-temporal changes are Land Cover, Shorelines and
sediment delivery using remote sensing data, GIS analysis, XRD, grain size and loss on ignition.
Results show there are significant changes of vegetation and shoreline in wetlands of
Comerong Island over time, including northern accretion (408344.46m2), eastern, middle and
southern erosion (727626.25m2) of the Island.
With an eco-geomorphological context, such insights about the nature of changes in coastal
wetlands are useful for sustainable risk assessment and management. The framework
demonstrated here for quantifying the current stressors of coastal wetlands could represents
an approach that could be profitably applied worldwide.
