Global sea level rise is expected to vary between 15cm and 88cm in 2100, the best estimate being 44cm as predicted in the IGCP third assessment report published in 2001. This means that the rate of sea level rise would be three times higher than its value of 1.5 mm /year as accepted for the 21th century. Coastal aquifers prone to salinization would be highly affected due to sea water intrusion and where land is subsiding the sea-level rise will be faster resulting in a corresponding exacerbated adverse impact.
