Everything about The Brahmaputra totally explained
The
Brahmaputra, also called Tsangpo-Brahmaputra, is a
trans-boundary river and one of the major
rivers of
Asia.
From its origin in southwestern
Tibet as the
Yarlung Tsangpo River, it flows across southern Tibet to break through the
Himalayas in great gorges and into
Arunachal Pradesh where it's known as
Dihang. It flows southwest through the Assam Valley as
Brahmaputra and south through
Bangladesh as the
Jamuna. There it merges with the
Ganga to form a vast delta. About 1,800 mi (2,900 km) long, the river is an important source for irrigation and transportation. Its upper course was long unknown, and its identity with the Yarlung Tsangpo was only established by exploration in 1884-86. This river is often called Tsangpo-Brahmaputra river.
In Bangladesh the river merges with the Ganga and splits into two the Hugli and Padma River.When it merges with the Ganges it forms the world's largest delta the Sunderbans.The Sunderbans is known for Tigers and mangrooves.
While most Indian and Bangladeshi rivers bear female names, this river has a rare male name, as it means "son of
Brahma" in
Sanskrit (putra means "son").
The Brahmaputra is navigable for most of its length. The lower reaches are sacred to
Hindus. The river is prone to catastrophic flooding in spring when the Himalayan snows melt. It is also one of the few rivers in the
world that exhibit a
tidal bore.
River course
Tibet
The
Yarlung Tsangpo originates in the
Jima Yangzong glacier near
Mount Kailash in the northern Himalayas. It then flows east for about 1700 km, at an average height of 4000 m, and is thus the highest of the major rivers in the world. At its easternmost point, it bends around
Mt. Namcha Barwa, and forms the
Yarlung Tsangpo Canyon which is considered the deepest in the world.
India
As the river enters
Arunachal Pradesh, it's called
Siang and makes a very rapid descend from its original height in Tibet, and finally appears in the plains, where it's called
Dihang. It flows for about 35 km and is joined by two other major rivers:
Dibang and
Lohit. From this point of confluence, the river becomes very wide and is called Brahmaputra. It is joined in
Sonitpur District by the Jia Bhoreli (named the
Kameng River where it flows from
Arunachal Pradesh) and flows through the entire stretch of
Assam. In Assam the river is sometimes as wide as 10 km. Between
Dibrugarh and
Lakhimpur districts the river divides into two channels---the northern
Kherkutia channel and the southern Brahmaputra channel. The two channels join again about 100 km downstream forming the
Majuli island. At
Guwahati near the ancient pilgrimage centre of
Hajo, the Brahmaputra cuts through the rocks of the Shillong Plateau, and is at its narrowest at 1 km bank-to-bank. Because the Brahmaputra is the narrowest at this point the
Battle of Saraighat was fought here. The first rail-cum-road bridge across the Brahmaputra was opened to traffic in April 1962 at Saraighat.
The old
Sanskrit name for the river is and the local name in Assam is .
The native inhabitants, for example, the
Bodos called the river, which means 'making a gurgling sound', later Sanskritized into .
When compared to the other major rivers in India, the Brahmaputra is less polluted but it has its own problems: petroleum refining units contribute most of the industrial pollution load into the basin along with other medium and small industries. The main problem facing the river basin is that of constant flooding. Floods have been occurring more often in recent years with deforestation, and other human activities being the major causes.
Bangladesh
In
Bangladesh, the Brahmaputra splits into two branches: the much larger branch continues due south as the
Jamuna and flows into the Lower
Ganges, locally called
Padma, while the older branch curves southeast as the lower Brahmaputra and flows into the
Meghna. Both paths eventually reconverge near
Chandpur in Bangladesh and flow out into the Bay of Bengal. However, the actual
Brahmaputra river in Bangladesh passes through the
Jamalpur and
Mymensingh district. Fed by the waters of the
Ganges and Brahmaputra, this river system forms the
Ganges Delta, the largest
river delta in the
world.
Flooding
During the monsoon season (June-October), floods are a common occurrence. Deforestation in the Brahmaputra watershed has resulted in increased siltation levels, flash floods, and soil erosion in critical downstream habitat, such as the
Kaziranga National Park in middle Assam. Occasionally, massive flooding causes huge losses to crops, life and property. Periodic flooding is a natural phonomenon which is ecologically important because it helps maintain the lowland grasslands and associated wildlife. Periodic floods also deposit fresh alluvium replenishing the fertile soil of the Brahmaputra River Valley. Thus flooding, agriculture, and agricultural practices are closely connected.
Transportation and navigation
Until Indian independence in 1947, the Brahmaputra was used as a major waterway. In the 1990s, the stretch between
Sadiya and
Dhubri in India was declared as National Waterway No.2., and it provides facilities for goods transportation. Recent years have seen a modest spurt in the growth of river cruises with the introduction of the cruise ship, "Charaidew", by Assam Bengal Navigation.
