BEIJING, China – A recent published study said that China’s capital city is sinking to the grounds by 11 centimeters (4 inches) every year.

Euan McKirdy mentioned in his article for CNN  that an international study led by Beijing-based researchers found out that the city is dropping by as much as 11 centimeters (4 inches) in some districts annually.

The city was so deprived of groundwater, which the study revealed to be the cause why the city is sinking.

The researchers used satellite imagery and GPS data to analyze topographical trends from 2003 to 2010 and found that the city, which is home for more than 20 million, was sinking at an alarming rate.

An article by Kirsten Silven for Inquisitr said the central districts are among the worst affected; with the main subsidence bowls distributed over the Chaoyang, Changping, Shunyi and Tongzhou districts.

Chaoyang, which is the eastern suburbs, is the worst affected as it has a subsidence of 11 cm per year.

The study noted that Beijing ranked as the fifth most water-stressed city in the world, and the urbanization of other parts of China put more stress on subterranean aquifers; making the situation worse.

Reports said the capital city alone requires 3.5 billion liters of water per year, and because of this high demands, the water, which has accumulated over thousands of years, is extracted in increasingly greater volumes and now-dried up the soil compacts.

Researchers say the rapid sinking could affect buildings and public works projects, including the city’s rail network.

The study was published this month and supported by the National Natural Science Foundation of China.
