Data quality


The current climate erosion overlays were determined using the Queensland Coastal Hazards Guideline (DERM, 2012a). The guideline requires erosion prone area widths to accommodate both short-term and long-term erosion for a specific planning period. The current climate erosion overlays reported here refer to short-term erosion prone areas only.

The extent of short-term erosion is determined by identifying the areas of the open coast already experiencing some degree of erosion, i.e. the presence of a sea wall or protective engineering structure, and areas where the dunes are substantially reduced by wave action. The erosion prone area is defined as the area bounded by the seaward limit of Queensland waters ? Highest Astronomical Tide (HAT) and on land adjacent to coastal waters as:

? a line measured 40 m landwards of the plan position of HAT except where approved revetments (e.g. sea walls) exist in which case the line is measured 10 metres landwards of the upper seaward edge of the revetment, irrespective of the presence of outcropping bedrock.

The guideline makes further provision for the assessment of the erosion hazard based on the potential impact of a ?design storm?. Whilst not considered for current climate, these provisions will were incorporated into the future climate erosion overlays.

To assist in the identification of the existing erosion prone areas two series of historical aerial photography (captured 05/1961 and 06/1964) were compared with the 2010 image mosaic of the Rockhampton coastline. This comparison enabled the identification of sections of the coastline that experience coastal recession or accretion during this time period. A current coastline was then digitised from the 2010 aerial photography and buffers applied to eroding sections of coast to represent the areal extent of coastal erosion hazard under current climate as described in the point above.
