Abstract
The impacts of climate change, including sea level rise and the increased frequency of storm surge events, will adversely affect infrastructure in a significant number of Australian coastal communities. In order to quantify this risk and develop suitable adaptation strategies, the Department of Climate Change and Energy Efficiency (DCCEE) commissioned the National Coastal Vulnerability Assessment (NCVA). With contributions from Geoscience Australia (GA) and the University of Tasmania, this first-pass national assessment has identified the extent and value of infrastructure that are potentially vulnerable to impacts of climate change. A number of fundamental national scale datasets underpinned the NCVA. A mid-resolution digital elevation model was used to model a series of sea level rise projections incorporating 1 in 100 year storm-tide estimates where available. The model outputs were overlain with a national coastal geomorphology dataset, titled the Smartline. The Smartline identified coastal landforms that are potentially unstable and may recede under the influence of rising sea level. These datasets were then overlain with Geoscience Australia's National Exposure Information System (NEXIS) to quantify the number and value of infrastructure elements (including residential and commercial buildings, roads and rail) potentially vulnerable to a range of sea-level rise and recession estimates for the year 2100.
