Description
Summary:Sea level rise has cause shoreline recession in several nations, although the potential physical and economic impacts have not been assessed due to the cost of data collection at a high resolution. a GIS-based coastal behavior model was developed to apply simple algorithms to assess the potential coastal impact of sea level rise, specifically for coastal re-entrants. The model can provide initial estimates of potential change; the next step is a spreadsheet-based hazard probability model. Both models together can lead to a rapid assessment of likely shoreline changes, with a grading of risks rather than a single impact zone identified in the GIS output. Applications to sites in southeastern Australia are made.
