China plans to build 1,000-km tunnel from Tibet, divert Brahmaputra water to to Xinjiang, says report

By | October 31, 2017

Beijing: Chinese language engineers are testing strategies that may very well be used to construct a 1,000-kilometre lengthy tunnel, the world’s longest, to divert water from Brahmaputra river in Tibet near Arunachal Pradesh to the parched Xinjiang area, a media report mentioned on Monday.

The transfer, that’s anticipated to “flip Xinjiang into California”, has raised issues amongst environmentalists about its doubtless affect on the Himalayan area, Hong Kong-based South China Morning Put up reported.

The proposed tunnel, which might drop down from the world’s highest plateau in a number of sections related by waterfalls, would offer water in China’s largest administrative division, comprising huge swathes of deserts and dry grasslands.

The water can be diverted from the Yarlung Tsangpo River in southern Tibet, which turns into the river Brahmaputra as soon as it enters India, to the Taklamakan desert in Xinjiang.

China’s longest tunnel is the 85-kilometre Dahuofang water venture in Liaoning province, whereas the world’s longest tunnel is the 137-kilometre essential water provide pipe beneath the town of New York.

India, a riparian state, has already flagged its issues to Beijing about varied dams being constructed by it on Brahmaputra river, which is named Yarlung Tsangpo in China. Beijing has been assuring India and Bangladesh, which can be a recipient of the waters from the river, that its dams had been of the run of river initiatives and never designed to storing water.

Wang Wei, a researcher who helped draft the newest Tibet-Xinjiang water tunnel proposal, which was submitted to the central authorities in March, mentioned greater than 100 scientists shaped completely different groups for the nationwide analysis effort.

He was a part of the workforce which was led by China’s high tunnelling knowledgeable, Wang Mengshu.

The workforce, in accordance with the report instructed to empty Brahmaputra at Sangri county in southern Tibet, near Arunachal Pradesh.

“Sangri county featured a big, comparatively flat valley that was excellent for the engineering venture. A synthetic island can be constructed in the course of the river to create fast turbulence, which may filter out sediment, and direct water to a nicely. The nicely may management the quantity of water flowing into the tunnel,” the report mentioned.

The Chinese language authorities began constructing a tunnel within the centre of Yunnan province in August that can be greater than 600-kilometre lengthy.

Researchers mentioned constructing the Yunnan tunnel can be a “rehearsal” of the brand new expertise, engineering strategies and tools wanted for the Tibet-Xinjiang tunnel, which might divert the Brahmaputra river to the Taklimakan Desert in Xinjiang, it mentioned.

Chinese language engineers say the Tibetan Plateau, also known as “the roof of the world”, stops the monsoon from Indian Ocean reaching Xinjiang leaving the Gobi Desert within the north and the Taklimakan Desert within the south unsuitable for human settlement.

In latest many years, Chinese language authorities departments, together with the Ministry of Water Sources, have give you engineering blueprints involving big dams, pumps and tunnels, the report mentioned.

The venture’s huge value, engineering challenges, doable environmental affect and the chance of protests by neighbouring nations have meant it has by no means left the drafting board. However Zhang Chuanqing, a researcher on the Chinese language Academy of Sciences’ Institute of Rock and Soil Mechanics in Wuhan, Hubei province, mentioned China was now taking a quiet, step-by-step method to convey it to life.

“The water diversion venture in central Yunnan is an illustration venture,” mentioned Zhang, who has performed a key position in lots of main Chinese language water tunnel initiatives, together with the one in Yunnan.

“It’s to indicate now we have the brains, muscle and instruments to construct super-long tunnels in hazardous terrains, and the associated fee doesn’t break the financial institution,” he was quoted as saying by the Put up.

The development of the tunnel on the Yunnan-Guizhou Plateau, the nation’s second-highest, would make political leaders extra assured in regards to the Tibet-Xinjiang venture and extra prone to approve it, he mentioned.
