The ground elevation in this area are very low, thus, inundation is a key hazard. In a 1% AEP event with 0.0 m SLR some fringe areas of the shoreline are impacted, mostly habitat around Point Henry. The salt pans are also likely to inundate, however this is of no consequence. In a 1% AEP event with 0.5 m SLR, the flood extents become more significant, potentially impacting some roads. Properties around Newcomb and Moolap are likely to be impacted by inundation in sea-level rise scenarios of 0.8 m and above.
The inundation vulnerability around Geelong is low. The shoreline is heavily modified, protection structures exist from east of Eastern Beach to Western Beach, mostly vertical seawalls. An overtopping assessment was undertaken and the vulnerability is high, however the consequences of overtopping inundation are likely to be low as long as the ongoing maintenance of the structures and active management of the foreshore is continued.
