Researchers predict that unless preventative measures are taking, climate change will put much of Bangkok under water.
Bangkok residents walk through their flooded community earlier this year.

700,000 lives at risk from floods, study finds
The lives of about 700,000 people and 1.16 million buildings in Bangkok will be seriously affected by floods caused by more rainfall and rising sea levels as a result of climate change in the next 40 years, a study has found.
The managing director of Phetchaburi-based Sirindhorn International Environmental Park, Seeree Supratid, said yesterday the projections were based on a study his team had been conducting to determine the impact of global warming on the capital and its vicinity.
The study, which used statistics from 2008 as a basis, predicts that western Bangkok will be partly covered by water due to a rise in the sea level.
The eastern part would be affected more often by flooding caused by increasing rainfall.
It is believed the higher sea level could result in a sea surge as far as 1.8 kilometres inland.The water level in affected areas would vary depending on their distance from the shore.
Mr Seeree said as many as 700,000 people were expected to be affected. About 250,000 of these would be in Don Muang, Nong Chok, Bang Kho Laem and Yannawa districts, and the country's main business hubs of Silom and Sathon.
The study team predicts 1.16 million buildings would be affected by floods of at least 10 centimetres in depth including 900,000 residential buildings.
"Without any prevention plan, we may have to use our ground floors for keeping boats," Mr Seeree said.
"We have not yet seen any serious plan to prepare people to cope with the situation. The impact will be severe if we do not try to prevent it."
Mr Seeree said rainfall in Bangkok had increased by about 15% over the past 30 years, with the sea level rising by an average of 1.3cm each year.
The reduction in water retention and green areas that absorb water had put the capital more at risk of being submerged.Bangkok has only 400 square kilometres of green areas, half of what it had 30 years ago.
"We are lucky that rainfall and the excessive amount of water have been absorbed by upper provinces. Without the so-called 'monkey cheek' or water retention areas, floods in the capital could be worse," Mr Seeree said.
"However, it doesn't mean that Bangkok is now safe. If the water volume released by the Chao Phraya Dam reaches 4,000 cubic metres per second, Bangkok won't be able to escape from the floods."
Mr Seeree urged the government to build a five-metre-high sea wall along 80km of the coast to protect the capital.
