China’s speedy tempo of dam constructions that features at the least eight new ones on the Brahmaputra River in Tibet has sparked issues concerning the Chinese language trying to tame India’s water provide. The proposed dams on the Yarlung Tsangpo river in Tibet are near the Indian border in Arunachal Pradesh.
On this area, the Chinese language have managed to assemble three dams inside a distance of 24 km on the Brahmaputra River over a interval of 10 years. This building of dams at an unprecedented tempo and scale has taken place in Tibet’s Sangri Lokha. Development of the same ‘triplet dam’ has been noticed on the Nyang river close to the city of Nyingchi in Tibet’s Nyingchi county.

Lokha, also referred to as Shanan lies within the northeast of Bhutan and south of Lhasa whereas Nyingchi is additional east, each bordering Arunachal Pradesh.
In an effort to discover out the purpose of those huge building initiatives, India As we speak OSINT workforce investigated them utilizing Google Earth photos.
The power to regulate India’s water provide within the arms of the Chinese language has at all times been a official concern. China can use this to trigger flash flooding or to divert water that might dry up rivers throughout India.
Zangmo Dam
A comparative evaluation of satellite tv for pc photos of the Zangmo dam reveals how its width has elevated fourfold from 100 m in 2012 when the development started to 400 m as seen on August 4, 2020, whereas the water ranges have risen nearly 150 m.
Thus, the reservoir which spans throughout nearly 10 km can maintain greater than 600 mn cubic metres of water, a sign {that a} huge quantity of water is beneath Chinese language management in Tibet.
Nevertheless, authorities sources say these dam constructions are being monitored carefully. “It’s one thing that has at all times been mentioned between the 2 governments carefully,” a authorities official monitoring developments on this regard asserted. Whereas claiming that the specter of China utilizing these dams to trigger flash flooding or block water to Indian territory is just not seen, sources stated, “For flash flooding, water needs to be gathered however there has not been something irregular that has been observed.”

New dams proposed on Brahmaputra
China has proposed to construct at the least eight extra dams on the Brahmaputra River in Tibet. These dams are to be constructed inside the subsequent 10 years at Bayu, Jiexi, Langta, Dakpa, Nang, Demo, Namcha and Metok cities that do not need greater than 100 households every. This has sparked hypothesis that the purpose of those dams is simply to construct reservoirs and export electrical power from Tibet to mainland China.
Want for shared knowledge on dam building, water movement
Satellite tv for pc photos very clearly point out that China is just not constructing numerous dams on the Brahmaputra River for the advantage of the folks of Tibet. The world is scantly populated and electrical energy calls for within the area could possibly be met with a single hydroelectricity venture just like the Zangmo dam.
The Chinese language might additionally purpose to make use of these dam reservoirs such because the Dagu dam to divert Brahmaputra’s water to dry areas in Xinjiang or Central China. Proof for such diversions is but to return to mild. Nevertheless, experiences have cited locals speaking about it lately.
The third and maybe essentially the most worrying clarification for China storing water at eleven dams on the Brahmaputra River could possibly be to regulate the water flowing into India.
Specialists really feel China’s dam building is a key concern and the Chinese language dispensation have to be extra clear over the difficulty. Director of the Kubernein Initiative, Ambika Vishwanath tracks water diplomacy and safety throughout the globe. She feels it isn’t simply the amount but additionally the standard of water that must be a matter of concern in the long term.

“There must be a better research on not simply the amount of water movement but additionally the standard which may be extraordinarily detrimental in the long term. It may well have an effect on folks’s lives in downstream areas. There may be little or no info and understanding of the area. The complete Himalayas is a black gap of knowledge,” Ambika says. She additional added, “Scientists, researchers want extra entry to the areas and require extra knowledge to know brief and long run affect to help in higher policymaking.”
Ambika additionally says that a technique of making certain extra transparency is joint initiatives, comparable to knowledge sharing or building of dams inside joint administration of river basins, however that doesn’t appear possible anytime quickly. “If there are joint constructions, tasks are additionally shared to safeguard installations on both facet,” she factors out.
Use of water provide as a weapon in opposition to India?
Blocking India’s water provide even for just a few days can result in rivers drying up throughout the nation.
However, many really feel low mendacity areas in India will probably be fully inundated if China instantly releases all this saved up water, as seen within the case of Three Gorges dam in Hubei province. A purposeful launch of water from all of the dams on the Brahmaputra can wreak havoc in India, many really feel.

As per Indo-Sino bilateral agreements, China is predicted to share knowledge with India in the course of the monsoon to ensure that the latter to maintain observe of water ranges and put together for floods.
After Pasighat in Arunachal Pradesh, the Brahmaputra River expands to nearly 10 km in width. Its width varies from 8 to 10 km in Assam. Bridges in these states are surprisingly smaller than the width of the river. Throughout monsoon yearly, the bridges get flooded with their abutments nearly at all times underwater.
Cautious monitoring of those dams will present a 15-day early warning since that is the time it takes for river water to journey from Tibet’s Lokha county to Pasighat in Arunachal Pradesh.
Zangmo, Gyatsa, and Dagu
There are three dams on the principle Brahmaputra River inbuilt unusually shut proximity to one another. These dams are situated inside a really brief distance of 24 km. With solely the one village of Gyatsa and its inhabitants of barely 150 households, having three dams is unprecedented.
Whereas the Zangmo dam has been commissioned, the Gyatsa dam is full and awaiting commissioning. The third and largest of the trio, the Dagu dam has been beneath building since 2017.
Dagu surprisingly has two inlets and two shops for water to move by the mountain regardless of it being a run of the river hydroelectricity dam. Such dams have electrical energy mills underground, in an space under the dam and don’t require extra tunnels for water movement.
This has led to doubts supported by rumours that Brahmaputra’s water could also be diverted to the dry Xinjiang deserts by underground tunnels utilizing Dagu dam. As soon as all three are full, the triplet dams will be capable to accumulate nearly a billion cubic meters of water of their reservoirs.
Pagsum, Langsai and Nyang
The three dams in Nyingchi county are being constructed on a tributary known as Nyang that feeds Brahmaputra River. The dams at Pagsum, Langsai and Nyang are a lot smaller in dimension however maintain sufficient water so as to add to the Brahmaputra River movement.
Land barrier dam
Round October and November of 2018, hearsay had it that China had clamped down on the Brahmaputra river and water movement had nearly come to a halt. Reviews of water being unusually muddy on the time had additionally come to mild.
Satellite tv for pc photos revealed a lot later that a big landslide from the southeastern face of Sodong Ri Mountain had blocked the Brahmaputra nearly fully.
Worldwide obligations dictate that China should search permission from downstream nations earlier than setting up any dam upstream on the Brahmaputra river. Regardless of its bilateral agreements with India, China nonetheless doesn’t share any knowledge on this regard.
Though New Delhi is paying a hefty sum of Rs 80 lakhs to Beijing for this knowledge annually, the response India will get from the Chinese language each time is the same- water within the Brahmaputra river washed the measuring devices away.
