Before its confluence with the Ganga, the Jamuna receives the combined waters of the BaralAtraiand Hurasagar Rivers on its right bank and becomes the point of departure of the large Dhaleswari River on its left bank.
Flooding[ edit ] Flooded villages along the Brahmaputra During the monsoon season June—Octoberfloods are a very common occurrence. Crevasse splay, a sedimentary fluvial deposit which forms when a stream breaks its natural or artificial levees and deposits sediment on a floodplain, are often formed due to a breach in levee, forming a lobe of sediments which progrades onto the adjacent floodplain.
The river has long formed a waterway between the Indian states of West Bengal and Assam, although, on occasion, political conflicts have disrupted the movement of traffic through Bangladesh.
Another important feature of the river is its tendency to flood. Extensive flooding is virtually an annual occurrence in the Brahmaputra valley during the summer monsoon. Hydrology[ edit ] The hydrology of the Brahmaputra River is characterized by its significant rates of sediment discharge, the large and variable flows, along with its rapid channel aggradations and accelerated rates of basin denudation.
An increasing number of hydroelectric stations have been completed in Assam, most notably the Kopili Hydel Project in the south of the state.
The height difference of the channel topography is often not more than 1m-2m. In Tibet the waters of the Brahmaputra are clear because little silt is carried downstream.

In Assam the deep channel of the Brahmaputra follows the southern bank closer than the northern. The banks of the river are mostly weakly cohesive sand and silts, which usually erodes through large scale slab failure, where previously deposited materials undergo scour and bank erosion during flood periods.
Yarlung Tsangpo River in Tibet. Bamboo thickets abound throughout Assam and Bangladesh. A region of significant tectonic activity has developed in the Jamuna River and is associated with the Himalayan uplift and development of the Bengal foredeep.
The river flow is strongly influenced by snow and ice melting of the glaciers, which are located mainly on the eastern Himalaya regions in the upstream parts of the basin. The Brahmaputra is navigable throughout the Bengal Plain and Assam upstream to Dibrugarhmiles 1, km from the sea.
Another major project, the Ranganadi plant, has been built in Arunachal Pradesh, which has considerably more generating capacity than the Kopili station.
The river valley in Assam is enclosed by hill ranges on the north, east, and south and receives more than inches 2, mm of rainfall annually, while in the Bengal Plain heavy rainfall—averaging 70 to inches—is reinforced by the huge discharge of the Tista, Torsa, and Jaldhaka rivers.
In the future, the consequences of local ground subsidence coupled with flood prevention propositions, for instance localised breakwaters, that increase flood-plain water depths outside the water breakers, may alter the water levels of the floodplains.
This final part of the river is called Meghna. Around towns and villages in the Assam Valley, the many fruit trees yield plantains, papayas, mangoes, and jackfruit. Lhasa receives about 16 inches mm annually. The most spectacular of these changes was the eastward diversion of the Tista River and the ensuing development of the new channel of the Jamuna, which occurred in with an exceptionally high flood in the Tista.
The Brahmaputra remained unbridged throughout its course in the plains until the Saraighat Bridge—carrying both road and rail traffic—was opened in near GuwahatiAssam. In the s and s, there was repeated speculation that mentioned Chinese plans to build a dam at the Great Bend, with a view to divert the waters to the north of the country.
The Tsangpo is spanned in several places by suspension bridges. This increase in discharge due to significant retreat of snow gives rise to severe catastrophic problems such as flood and erosion. The hilly margins of the plain are inhabited by the tribal Garo, Khasiand Hajong of Meghalaya state in India.
A second crossing in Assam, the Kalia Bhomora road bridge near Tezpurwas opened in The major Himalayan Rivers are the Indus, Ganges, and Brahmaputra. These rivers are long, and are joined by many large and important tributaries. Himalayan rivers have long courses from their source to sea (in India Arabian sea and Bay of Bengal).
(Asia) A river flowing primarily in northern India; flows southwest, parallel to the Himalayas, before merging with the Brahmaputra River and emptying into the Bay of Bengal in Bangladesh. Indus (Asia) One of the major rivers of Asia; it flows southwest through Pakistan; it is the origin of "India".
Great rivers are the cultural and economic backbone of South Asia. The Ganges, Indus and Brahmaputra have contributed to the rise and prosperity of some of the earliest civilizations in history and today are the source of livelihood for millions.
Brahmaputra River, Bengali Jamuna, Tibetan Tsangpo, Chinese (Pinyin) Yarlung Zangbo Jiang or (Wade-Giles romanization) Ya-lu-tsang-pu Chiang, major river of Central and South Asia. It flows some 1, miles (2, km) from its source in the Himalayas to its confluence with the Ganges (Ganga) River, after which the mingled waters of the two rivers empty into the Bay of Bengal.
The Brahmaputra (/ ˌ b r ɑː m ə ˈ p uː t r ə /) is one of the major rivers of Asia, a trans-boundary river which flows through China, India and mint-body.com: Bay of Bengal.
