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. -
Is the Three-Gorges Dam Sustainable? LO: to Investigate How Human Activity Is Affecting the Longest River in Asia
Is the Three-Gorges dam sustainable? LO: To investigate how human activity is affecting the longest river in Asia The Yangtze is the longest river in Asia, and the third- longest in the world. It flows for 6,418 kilometres (3,988 mi) from the glaciers on the Tibetan Plateau before emptying into the East China Sea at Shanghai Starter: What connects these images? The beginning of a river is called the source. In this case the Yangtze forms due to being fed by glaciers (huge masses rivers of ice) high up in the mountains of Tibet.

Physical Geography of the Punjab
19 Gosal: Physical Geography of Punjab Physical Geography of the Punjab G. S. Gosal Formerly Professor of Geography, Punjab University, Chandigarh ________________________________________________________________ Located in the northwestern part of the Indian sub-continent, the Punjab served as a bridge between the east, the middle east, and central Asia assigning it considerable regional importance. The region is enclosed between the Himalayas in the north and the Rajputana desert in the south, and its rich alluvial plain is composed of silt deposited by the rivers - Satluj, Beas, Ravi, Chanab and Jhelam. The paper provides a detailed description of Punjab’s physical landscape and its general climatic conditions which created its history and culture and made it the bread basket of the subcontinent. ________________________________________________________________ Introduction Herodotus, an ancient Greek scholar, who lived from 484 BCE to 425 BCE, was often referred to as the ‘father of history’, the ‘father of ethnography’, and a great scholar of geography of his time. Some 2500 years ago he made a classic statement: ‘All history should be studied geographically, and all geography historically’. In this statement Herodotus was essentially emphasizing the inseparability of time and space, and a close relationship between history and geography. After all, historical events do not take place in the air, their base is always the earth. For a proper understanding of history, therefore, the base, that is the earth, must be known closely. The physical earth and the man living on it in their full, multi-dimensional relationships constitute the reality of the earth. There is no doubt that human ingenuity, innovations, technological capabilities, and aspirations are very potent factors in shaping and reshaping places and regions, as also in giving rise to new events, but the physical environmental base has its own role to play. -
Ganga As Perceived by Some Ganga Lovers Mother Ganga's Rights Are Our Rights
Ganga as Perceived by Some Ganga Lovers Mother Ganga’s Rights Are Our Rights Pujya Swami Chidanand Saraswati Nearly 500 million people depend every day on the Ganga and Her tributaries for life itself. Like the most loving of mothers, She has served us, nourished us and enabled us to grow as a people, without hesitation, without discrimination, without vacation for millennia. Regardless of what we have done to Her, the Ganga continues in Her steady fl ow, providing the waters that offer nourishment, livelihoods, faith and hope: the waters that represents the very life-blood of our nation. If one may think of the planet Earth as a body, its trees would be its lungs, its rivers would be its veins, and the Ganga would be its very soul. For pilgrims, Her course is a lure: From Gaumukh, where she emerges like a beacon of hope from icy glaciers, to the Prayag of Allahabad, where Mother Ganga stretches out Her glorious hands to become one with the Yamuna and Saraswati Rivers, to Ganga Sagar, where She fi nally merges with the ocean in a tender embrace. As all oceans unite together, Ganga’s reach stretches far beyond national borders. All are Her children. For perhaps a billion people, Mother Ganga is a living goddess who can elevate the soul to blissful union with the Divine. She provides benediction for infants, hope for worshipful adults, and the promise of liberation for the dying and deceased. Every year, millions come to bathe in Ganga’s waters as a holy act of worship: closing their eyes in deep prayer as they reverently enter the waters equated with Divinity itself. -

In this work, we provide a rigorous ap- Changjiang River praisal of the changes in streamflow, sediment load, and sediment composition at multiple time scales throughout the uCR based on data in 1950–2017. We observed that a decreasing trend in annual streamflow has emerged since 2015 at Yichang, the outlet of the uCR basin, although the changes were statistically insignificant for the first 65 years. The annual sediment load has decreased progressively and substantially, e.g., by97%in 2010s compared to 1950s at Yichang. The Three Gorges Dam and the new large dams in the upstream mainstem accelerated the sediment load reduction in 2003 and 2014, respectively.
