NT Department of Land Resource Management NT Remote Communities Storm Tide Study and Inundation Mapping J1507-PR001B 2 Systems Engineering Australia Pty Ltd July 2016 Of these 5 identified study regions: Communities, towns and cities in Stage 1 have been covered by the Greater Darwin Storm Surge Study and Mapping which was completed in 2010 (SEA 2006, 2010; GHD 2010); The Stage 2 Gulf of Carpentaria Storm Surge Study for communities and associated mapping, undertaken jointly with the Queensland Government, is also complete (GHD 2013); Stage 3 (West Coast), 4 (Tiwi Islands), and 5 (Arnhem Coast) are the subject of this Study, encompassing the communities of: o West Coast: Wadeye o Tiwi Islands: Wurrumiyanga Pirlangimpi Milikapiti o Arnhem Coast: Minjilang Warruwi Maningrida Milingimbi Galiwinku 1.2 Approach The methodology herein is based on the recommendations from: Storm tide Scoping Study for Major Remote Towns and Indigenous Communities - West Coast, Arnhem Coast and Tiwi Islands (GHD-SEA (2015) The Study also builds on the collective knowledge and experience from numerous past studies of the NT region (refer GHD-SEA (2015)) and also implicitly adopts the guideline recommendations within: Queensland Climate Change and Community Vulnerability to Tropical Cyclones Ocean Hazards Assessment (QCCC) study (Harper 2001); Engineers Australia Guidelines for Responding to the Effects of Climate Change in Coastal and Ocean Engineering (Harper 2012), and Queensland Coastal Hazard Adaptation Strategy Pilot Study (GHD 2012). In addition to this report, mapped Year 2100 water level surfaces were an additional deliverable of the Study, as specified in Appendix A.
