The study outcomes provided inundation maps showing storm tide elevation depth that corresponds to a specific return perios risk or ARI. The provided storm tide probability levels are 100,1000 and10,000 year ARI. The inundation extent shows the total storm surge (technical terminology is storm tide) hazard risk due to tropical cyclones in terms of the ocean water level comprising the combined effects of astronomical tide plus storm surge plus wave setup for three statistical Average Recurrence Intervals (ARI) at a nearby open coast location as noted in the map. The Primary Storm Surge (PSS) Zone refers to the extent of inundation for a storm tide event of 100 year ARI. The Secondary Storm Surge (SSS) Zone refers to the further extent of inundation for a storm tide event of 1000 year ARI. The Extreme Storm Surge Zone refers to the further extent of inundation for a storm tide event of 10000 year ARI. The extent of PSS is used for land use planning. The extent of SSS is an additional information for risk analysis. The extent do not include the possible effects of very localised wave runup. The storm surge extend boundaries polygon collected via geographic Information system (ArcGIS). The ESRI Geodatabase, MapInfo Table and Google Earth KML derived using FME Workbench. The published map is derived from the ESRI Shape using Microstation Bentley MicroStation Design (V8) software. The core attributes information associated with the storm surge extents was derived from the original map's legend and annotations.

The technical information forming the basis of the storm surge inundation extent is contanined in the report prepared for by GHD Pty Ltd. The storm surge extent along the coast: The storm surge inundation extent was interpolated by DLRM using the significant wave height values (100, 1000 and 10,000 ARI) in metres with the 1 metre Northern Territory topographic contours to derived the boundary line along the coast.
