Developing a Spatial Tool for Assessing Coastal Community and Identifying Infrastructure at Risk

A recent trend of sea level shows constant rising. Sea level rise has caused asignificant risk to seaside areas. This study examines the potential effect ofclimate change and rising sea levels on coastal regions and evaluates the susceptibilityof coastal areas in Inverloch, Melbourne Australia. A model ofHypothetically Flooded Zones, based on LiDAR data was built, processed andmanipulated in ArcGIS. Through applying this model, the effect of rising sealevel on the infrastructures such as buildings, dwellings, roads, land use andthe population was assessed. Elevation data sets of varying resolution and accuracyhave been processed to show the improved quality of LiDAR datacontributes to a more precise delineation of flood-prone coastal lands. Afterthe susceptible areas to sea level rise were delineated, the worst-case scenariowas calculated (based on the increase in sea level projected for 2100) and itwould impacts about 0.86% of roads, 221 of different building infrastructures.This method can be used in other areas to protect the coasts due to rapidchanges caused by climate change.Validerad;2021;Nivå 1;2021-01-18 (alebob)
