Second-Pass Assessment of Potential Exposure to Shoreline Change in New South Wales, Australia, Using a Sediment Compartments Framework

Abstract: Abstract:The impacts of coastal erosion are expected to increase through the present century, and beyond, as accelerating global mean sea-level rise begins to enhance or dominate local shoreline dynamics. In many cases, beach (and shoreline) response to sea-level rise will not be limited to passive inundation, but may be amplified or moderated by sediment redistribution between the beach and the broader coastal sedimentary system. We describe a simple and scalable approach for estimating the potential for beac… Show more

“…Comparatively, our results show the potential future growth of exposure to inundation within estuaries to be a far greater problem in NSW than that of exposure to open coast erosion, which while nevertheless significant 52 , is an order of magnitude less than the results presented here. Overall this exposure assessment finds esturine tidal inundation to be a major coastal management issue, highlighting the need for coastal and floodplain management and planning to manage risk to current development and to avoid the unnecessary growth of risk into the future.…”

“…The geocoded urban and rural address system (GURAS) 66 was used to identify properties that were predicted to be exposed to inundation under each scenario using a similar approach to that adopted in the recent 2 nd pass erosion assessment 52 . The GURAS database stores address point data within cadastral lots.…”

“…A key component in assessing the dynamic behaviour of a coastal cell [1,2] is knowledge of the sediment budget [3][4][5], including sediment fluxes in the cross-shore and alongshore. Cross-shore transport includes sediment movement to and from dunes (e.g., [6]), through the intertidal to sub-tidal beach (e.g., [7]) and out to and beyond the depth of closure (e.g., [8]).…”

“…Beach erosion and shoreline recession caused by large storms and the gradual and ongoing redistribution of coastal sediments may result in damage to or total loss of coastal properties, infrastructure, recreational amenity, and natural habitats (Harley et al 2017;Kinsela et al 2017). Projected sea-level rise under future climate scenarios is expected to increase the impacts of storm-related beach erosion events and enhance shoreline recession along unstable coasts (Fitzgerald et al 2008).…”
