Suvarnabhumi Airport

Bangkok lies about two meters above sea level. This low ground level causes problems for the protection of the city against floods during the monsoon season. Often after a downpour, water in canals and the river overflows the banks, resulting in massive floods. The Bangkok Metropolitan Administration (BMA) has recently installed higher planks alongside some canals to keep water levels from reaching street level. There are however some downsides for Bangkok's extensive canal routes, as the city is rumored to be sinking an average of two inches a year as it lies entirely on a swamp.  Some reports say that the city is sinking as much as four inches a year, and this combined with rising sea levels will leave Bangkok under 50 cm to 100 cm of water by 2025.
