Flooding of Hobsons Bay Coastal Areas in 2100 in worst case scenario

Post by Anthony Ang on Sat Dec 18, 2010 6:36 am

OzCoast has developed maps for 3 sea-level rise scenarios of 0.5m, 0.8m and 1.1m by the year 2100 for Australian coastal areas, as a result of global warming and melting of the polar ice.

The sea-level rise scenarios have been combined with a nominal highest astronomical tide (HAT) value for the region, and are based on IPCC projections and more recent science.

The maps are based on a simple 'bucket fill' approach and should be considered as approximate only. The actual impacts may vary as this model does not take account of existing sea walls, storm surge, erosion or other local factors.

I have extracted the sea level rise map for the Hobsons Bay coastal areas, for the worst scenario of a sea-level rise of 1.1 metre. Click here for the map.

Move the mouse over the map below to bring up the 4 buttons at the bottom right hand corner. Hovering the mouse over each button will bring up its tooltip. You can zoom in/out to have a closeup view of specific areas using either the mouse scroll wheel or the /- button. You can drag the map around by holding the mouse. To return the map to its original position, click the third "Go home" button. Click the last button if you want to have a full screen view.

It will be interesting to find out whether our homes will be affected but by the year 2100, perhaps only our babies will still be around and mankind may have already overcome the problem of climate change or new technologies may have emerged to mitigate its consequences.

It should also be noted that IF this does occur, and that's a big IF, then the whole world will be in strife, not just Hobsons Bay. There are many cities around the world close to the waters edge, that would be flooded according to the worst-case scenario. It should also be noted, that areas next to rivers would also be affected. According to the latest maps, the Maribyrnong river would be flooded so suburbs such as Yarraville, Footscray, Maribyrnong, Edgewater etc., would be flooded. Likewise the Docklands and even the CBD may be flooded, as well as bayside eastern suburbs such Port Melbourne, Elwood, St Kilda etc etc.
