| Abstract | The Changjiang (Yangtze River) in southern China is third largest river in the world based on discharge. Changjiang headwaters are in the rugged Tibetan highlands in western China and flows eastward for 6,300 km before reaching the sea near Shanghai. The river is generally divided into upper and lower sections based on physiography. In the upper basin in western China the Changjiang and tributaries are deeply incised, mountain bedrock streams. Downstream of the Three Gorges the Changjiang is bounded by broad alluvial valleys with a complex river-lake system that support intensive cultivation. Three Gorges has been considered for a dam site on the Changjiang since the 1930s. Dam construction was approved by the Chinese National People's Congress during 1992. It became fully operational in 2008. The position of leading advocates for the dam focused on hydroelectric power generation, downstream flood control and river navigation. But potential environmental and ecological problems also attracted widespread attention.Dam operation has altered discharge characteristics and channel sediment load downstream. However, how and to what extent the Three Gorges Dam (TGD) has, and will in the future, affect the physical environment and ecology conditions on the mainstream and adjoining lakes is only now beginning to emerge. We now have fourteen years of data since the dam became fully operational and are better able to evaluate the downstream impact. The work presented by experts in th... |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
