China-Mekong China-Mekong Message from discussion SCMP: China to dam world's highest river Apr 24 2010, 5:26 am Kevin Yuk-shing Li China to dam world's highest river S.N.M. Abdi in Calcutta and Stephen Chen and Kristine Kwok in Beijing Source: South China Morning Post (Hong Kong). Apr 24, 2010. Beijing has admitted to New Delhi that the mainland is building a dam on the Yarlung Zangbo River near its disputed border with India. The river originates in Tibet and flows into India as the Brahmaputra - a major waterway on which millions of people depend. Chinese officials told visiting Indian External Affairs Minister S.M. Krishna in a closed-door meeting this month a hydropower project was being built at Zangmu in the Tibet Autonomous Region's Shannan prefecture, the Times of India reported. Mainland experts involved in the project confirmed the hydropower plan for the river yesterday and said four other, similar dams would be built in a deep valley between Sangri and Jiacha counties. The total power capacity of the dams, once completed, would be "several times" bigger than the massive Three Gorges Dam. Electricity generated from the hydropower plant at Zangmu will be sold to South and Southeast Asian countries such as Myanmar, Thailand, Bangladesh, Laos and Cambodia. The money raised will then be used to fund the other dams, according to a preliminary report by mainland experts. Eventually, the dams will generate power to meet the fast growing demand in Guangdong and Hong Kong. Guangdong, the country's primary manufacturing base, now relies heavily on Yunnan and Guangxi for power. But the two western provinces are undergoing rapid industrialisation, increasing their own use of electricity, and the country needs to look further west to build more generating capacity. "The ultimate goal for the Yarlung Zangbo project is to supply electricity to Guangdong and Hong Kong. The peak season for electricity usage in these regions falls exactly on the flooding season for the Yarlung Zangbo. It will be an ideal match," the report says. While reports of Beijing's plan to dam the Yarlung Zangbo have been circulating for years, this month's meeting was the first time the country had admitted the plan to India. New Delhi is worried that the Chinese dams will affect India's water supply and destroy the ecological balance in the Himalayan region. Northeastern Indian states, whose agriculture and industry rely heavily on the Brahmaputra, are particularly alarmed. The damming of the Yarlung Zangbo, the highest major river in the world, will also give Beijing direct control of the water supply to more than 90,000 square kilometres of land over which China claims sovereignty but which is under the control of India. Chinese officials told India that Beijing had no obligation to reveal its plan to New Delhi but did so to build trust and ease tensions. Beijing said the hydropower plants would not affect water flows into India. The Zangmu plant has a designed capacity of 500 megawatts, according to a paper published in the academic journal Sichuan Water Power in February by Yuan Guodong , an engineer from the 11th platoon of the hydropower construction regiment under the People's Armed Police Force. On the mainland, the duties of the armed police include dam- building and mining, particularly when these take place in strategically sensitive areas. The dam lies southeast of Lhasa at an altitude of 3,260 metres, in an area subject to frequent extreme weather, the paper said. Ordinary construction materials could not ensure the dam's stability, and special technology developed by China's space industry programme was being utilised. The cement, for instance, was developed by laboratories at the Xichang satellite launch centre, it said. The experience gained building it would make building even bigger dams at high altitude easier. The damming of the Yarlung Zangbo was first suggested in the 1960s, but the idea was never looked into seriously until more recently because of the almost insurmountable engineering challenges such an undertaking must confront. The absence of proper roads and sufficient oxygen, labour, equipment and technology has severely limited the construction of hydropower stations in Tibet, even as the mainland has gone on a dam-building frenzy in the past decade, putting up hydropower stations in nearly every possible location in nearby Sichuan and Yunnan. More than 99 per cent of Tibet's hydropower potential of 1,764 billion kilowatt-hours of electricity a year remains untapped. Yan Zhiyong , the general manager of China Hydropower Engineering Consulting Group, told China Energy News that nearly all the major obstacles to damming the Yarlung Zangbo had been overcome. He said China was under huge pressure to switch to a low-carbon-emission economy, giving the project a sense of urgency. "Tibet has the largest stock of hydropower among all provinces," Yan said. "Exporting Tibetan electricity to eastern provinces will significantly ease China's energy shortage problem." Yan said major challenges would come from the region's fragile ecology and the native Tibetan population. Zhang Guihong , who studies Sino-Indian relations at Fudan University in Shanghai, warned that the project could become a new flashpoint between China and India. He said China had the right to build dams on its territory, "but if the project is going to affect other countries along the lower reaches of the river, China has to notify relevant governments as early as possible, so that they can be better prepared". Anant Krishnan, a foreign affairs expert in India, said international law allowed China to build hydro-power stations as long as the projects did not divert or substantially alter the course of rivers. But he said China's aggressive damming of rivers in its territory would affect its ties with countries on their lower reaches. "India is just as alarmed about dams on the Yarlung Zangbo as Thailand, Laos, Vietnam and Cambodia are about China's dams on the Mekong River in Yunnan," he said. -- You received this message because you are subscribed to the Google Groups "China- Mekong" group.

  • Three Gorges Dam Hydroelectric Power Plant
    Three Gorges Dam Hydroelectric Power Plant The Three Gorges Dam Project (TGP) is the world's largest hydropower complex project located in one of the three gorges of the Yangtze River: the Xilingxia Gorge in Hubei province, China. The gorge controls approximately one million square kilometres of drainage area and averages a runoff of 451 billion cubic metres annually. China Three Gorges Corporation (CTGPC) acts as the legal entity for TGP and is responsible for the construction, operation and financing of the project. Construction on the Three Gorges Dam was completed in 2008. The dam stands 185m high and 2,309m wide, making it the world's largest hydro plant, well ahead of Brazil's 12,600MW Itaipu installation. A total of 32 main power generators are planned to operate off the dam, of which 12 sets on the right bank and 14 sets on the left were installed in 2006 and 2008, respectively. They were operational in October 2008 and generated a total of 18,300MW. Another six generators are being installed underground and are expected to become fully operational by the end of 2011. These six were added to the project in 2002. The first three became operational in June 2011. The third generator unit (Unit 30) completed a 72 hour test run in July 2011. The first underground unit (Unit 32) began operations in May 2011 and the second (Unit 31) commenced commercial operations in June 2011. Once the additional generators are all installed, the plant will produce 22,500MW of electricity. Three Gorges project The Three Gorges Dam project involves harnessing the Yangtze River, Asia's longest stretch of water, to generate prodigious amounts of electricity.

  • Three Gorges Dam in Hubei, China: a Cost and Benefit Analysis
    Economic Analysis of Public Policy Professor Yoshitsugu Kanemoto Graduate School of Public Policy, University of Tokyo Final Report Three Gorges Dam in Hubei, China: A Cost and Benefit Analysis Felipe Francisco De Souza Graduate School of Engineering, University of Tokyo Baozhi Gu, Kenji Kurotobi Graduate School of Public Policy, University of Tokyo Yuri Kim Graduate School of Frontier Sciences, University of Tokyo August 2013 Executive Summary Situated on a canyon known as the Three Gorges in Hubei, China, Yangtze River’s Three Gorges Dam is the world’s largest power station in terms of installed capacity (22,500 MW). The project was initiated by the Chinese government in 1994, with the support of different international cooperation agencies, for three main reasons. First of all, it would generate hydroelectricity to meet China’s rapidly increasing demand. Second, the Three Gorges Dam would protect millions of people living along the river from potential floods. And finally, it would transform a 600- kilometre stretch of the fast-flowing river into a smooth navigable waterway for vessels and provide business opportunities to western landlocked provinces. The Chinese government regards this project as a historic engineering, social and economic success, with the design of sophisticated large turbines, and a move toward limiting greenhouse gas emissions. However, the dam has been a controversial topic, the reason why a cost and benefit analysis was developed to understand all possible variables related to this gigantic project and its complicated development process. For the evaluation of major benefit components, special care was taken to understand flood control (and dam’s capacity to control 100 years events); electricity generation (and the reduction of CO2 emissions); and the enhanced shipping capacity (allowing the transit of large quantities of cargos).

  • Stability Assessment of the Three-Gorges Dam Foundation, China, Using Physical and Numerical Modeling—Part I
    ARTICLE IN PRESS International Journal of Rock Mechanics & Mining Sciences 40 (2003) 609–631 Stability assessment of the Three-Gorges Dam foundation, China, using physical and numerical modeling—Part I: physical model tests Jian Liua,b,*, Xia-Ting Fenga, Xiu-Li Dingb, Jie Zhangb, Deng-Ming Yueb a Institute of Rock and Soil Mechanics, Chinese Academy of Sciences, Xiaohongshan, Wuhan, Hubei 430071, China b Yangtze River Scientific Research Institute, Wuhan 430019, China Accepted 31 March 2003 Abstract Foundation stability is one of the most important factors influencing the safety of a concrete dam and has been one of the key technical problems in the design of the Three-Gorges Project. The major difficulties lie in two facts. The first one is that the dam foundation consists of rock blocks, with joints and so-called ‘rock bridges’ and the gently dipping joints play a critical role in the foundation stability against sliding. The second one is that, even in the regions where the gently dipping fractures are most developed, there are no through-going sliding paths in the rock mass due to the existence of the rock bridges; so the dam could slide only if some of the rock bridges fail, so as to create at least one through-going sliding path. To date, due to unavoidable shortcomings in physical and numerical modeling techniques, there is not a single satisfactory method to solve the problem completely. For this reason, the integration of multiple methods was adopted in this study and proved to be an effective and reliable approach. This Part I paper describes work based on the results of geological investigations and mechanical tests, relating to the geological and geomechanical models of the Three-Gorges Dam, and then a systematic study procedure was developed to carry out the stability assessment project.

  • How Beijing Accounts for the Cost of the Three Gorges Dam
    How Beijing Accounts for the Cost of the Three Gorges Dam By Tang Ying Sound of Hope Radio Network China's Three Gorges Dam in central China's Hubei province on July 22, 2009. (AFP/AFP/Getty Images) Built as a symbol of China's modernization and touted by the Chinese regime as a social and economic success, the Three Gorges hydroelectric river dam spans the Yangtze River in China’s central Hubei Province. The Three Gorges Dam is the largest and most controversial hydroelectric project in history. Debate has surrounded the project for decades, beginning at the proposal phase in the 1980s and continuing throughout subsequent construction. The project has been plagued by corruption, escalating costs, technological problems, human rights violations, and resettlement difficulties. The dam has caused flooding to numerous archaeological and cultural sites, the displacement of about 1.24 million people, and significant ecological changes, including an increased risk of landslides. During the vetting phase of the project, two-thirds of the delegates voted in favor, and the Three Gorges Dam was officially approved by China's People's Congress in 1992. The price of the dam has skyrocketed from the approved 57 billion yuan (US$8.35 billion) to 180 billion yuan (over US$26 billion), by the end of 2008. Officials now claim they will need another 100 billion yuan (US$14.6 billion) to deal with the problems created by the dam. Among the problems is the current water shortage in China. “There's been a lot less rain, a lot more drought, and the potential for increased disease,” says George Davis, a tropical medicine specialist at the George Washington University Medical Center who has worked in the Yangtze River Basin and nearby provinces for 24 years.

  • Impact of Three Gorges Dam on the Upstream of Yangtze River and Its Tributaries
    Impact of Three Gorges Dam on the Upstream of Yangtze River and its Tributaries Data source The construction of the dam started in December 1994. Even though it was opened in 2003, the construc- tion and addition of turbines and ship lift continued until December 2015. to understand the change brought by the construction, satellite images of the region before 1994 and after 2015 were required. While searching for satellite images for the analysis, first preference was given to a clear cloudless image that shows a significant portion of the Yangtze River upstream of the Dam. The geographic area where the dam is located is observed to have sub-tropical monsoonal climate. Because of this reason, most of the im- ages found were fully or partially covered by clouds. A collection of images was assessed in USGS Earth Ex- plorer and in EarthData to find the appropriate images for the project. Another criterion that dictated the data search was the time of the year. To match the atmospheric condition between the two comparing im- ages, both were chosen from the same time of the year. The images are products of U.S. Geological Survey, created and shared for educational purposes. Landsat Fig. 2: A portion images were chosen as the source of the dataset because of its vast collection of available data. Additional- of the main river ly, Landsat missions goes as far back as 1972, producing multispectral data with resolution appropriate enough for the scope of this project.

Number of projects listed under China’s new five-year plan are going to be built very close to the border of the two nations. This has raised more questions on China’s intention behind building water projects so close to national boundaries. In news: China’s new Five-Year Plan outlines push for key strategic projects Placing it in syllabus: Foreign Affairs Dimensions What does the plan aim to do? Geographical Aspects (Given the Map As well) Importance of the River to India Importance of the River to China What is the conflict about? Agreements Signed and problems with the agreement Impact of the plan and India’s options Content: What does the plan aim to do? China formally approved the outline of its 14th Five-Year Plan (2021-2025), which highlights a number of key strategic projects to be pursued as a priority. The major projects of concern for India include: the first dam in Tibet on the lower reaches of the Yarlung Zangbo or Brahmaputra In this Project, China could build up to 60 gigawatts (GW) of generation capacity on the river which would make it the world’s biggest hydropower project, overtaking China’s 22.5 GW Three Gorges Dam. a Sichuan-Tibet railway line near the India border, and a push for self-sufficiency in emerging industries such as Artificial Intelligence (AI). Other Important Facts: China’s new five-year plan calls for a move toward less dependence on the outside world, both for advanced technology and as a source of final demand.
