NT Department of Land Resource Management NT Remote Communities Storm Tide Study and Inundation Mapping J1507-PR001B 44 Systems Engineering Australia Pty Ltd July 2016 The following results (Table 4-3 and Figure 4-3)are relative to the local dune crest or nominal lowest floodable land at each site, which is an indication of potential flood hazard. It can be seen that Milingimbi is the most impacted, followed by Warruwi, Milikapiti and Minjilang. The remaining sites of Wadeye, Warrumiyanga and Pirlangimpi are generally not impacted. Maningrida and Galiwinku are protected by high elevation. Table 4-3 Total Storm Tide Levels (m Crest) by Year 2100.
