A report by the University of Southampton's school of civil engineering and the environment, Risk Management Solutions, CIRED/Meteo-France and the OECD highlights 10 of the world's port cities most exposed to coastal flooding, both today and by 2070. These are the 10 most at risk. All but one are in Asian developing countries.
Bangkok is believed to have between 15-20 million inhabitants and is one of the main gateways to Asia. It is located on both sides of the Chao Phraya River and has many river deltas and canals within its province.
It lies just 2 metres above sea level and extensive flooding occurs especially in the monsoon season.
Some reports say that Bangkok is sinking, and combined with climate change and population increase, from 907,000 people exposed to flooding the figure is expected to reach 5.1 million and may leave the city struggling to stay above water.
