NT Department of Land Resource Management NT Remote Communities Storm Tide Study and Inundation Mapping J1507-PR001B 42 Systems Engineering Australia Pty Ltd July 2016 4.1 Estimated Total Storm Tide Levels by the Year 2100 These are presented below in tabular (Table 4-1) and graphical (Figure 4-1) formats. Sites are listed from west to east for a geographical context. The highest absolute levels can be seen to be indicated at Wadeye and Milingimbi. Note that the estimates for 10,000 y ARI will be less reliable than the others due to the decreasing number of events being simulated. Table 4-1 Total Storm Tide Levels (m AHD) by Year 2100.
