Rising sea levels - what is the impact on Singapore's coastline?? #2

The WWF report's estimate of sea level change comes on the back of previous estimates from :

a] the IPCC (Intergovernmental Panel on Climate Change 4th Assessment Report) which predicted a range of possibilities based on various scenarios. The worst case scenario being 26-59 cm for the 21st century; and

b] a report by Siddall et al, Nature Geoscience 2, 571 - 575 (2009), projecting a rise of 7-82 cm rise in sea levels; and

c] a report by Grinsted et al,Climate Dynamics 2009, forecasting a meter rise in sea levels.

How will Singapore be affected?

It's hard to tell for sure since there is very little in terms of survey data out there. But I came across this cool website put up by some NUS students called 'Mapping Potential Sea Level Rise in Singapore' with some simulations and projections done using the 2001 IPCC Report.

The 2 figures below show projections based on an 82cm and 120cm increase in sea levels. For more info please go to their website.
