In recent years we have seen on more than one occasion as Bangkok has been flooded during heavy monsoon rains. Soon after, the water ends up draining the network of canals to the river Chao Phraya that passes through half the city.
However, it is increasingly likely as the city flooded, as experts warn Chulalongkorn University, Bangkok is sinking an average of 10 millimeters per year.
If urgent measures are not taken experts predict that over a period of 30 to 50 years Bangkok could be covered by water.
Bangkok is sinking
The city, along the river emerged in the eighteenth century, rests on a swamp that is giving by the extraction of groundwater, the natural movements of the earth’s crust and heavy building skyscrapers, among other factors.
The Bangkok Metropolitan Administration has taken steps to control and prohibit urban buildings of more than twelve meters prone to flooding and the construction of seven large drainage tunnels areas.Similarly, there have arisen with some channels dikes and strengthened the area near the Chao Phraya River.
Even it has been to raise the construction of a huge retaining wall that protects the entire city.
Up to two centimeters a year
There are areas east of the city that are decreasing their level faster, as in Ramkhamhaeng and Lat Krabang, two centimeters and one, respectively. And on average, the entire city falls 10 millimeters per year.
Meanwhile, south of the city, the coastal areas of the neighboring provinces, Samut Sakhon and Samut Prakan, are being eroded by the sea. To counteract the effect is being built bamboo walls and planting trees in order to reinforce the mangroves.
