The Tsangpo [02.28.09]
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 Zangbo River, it flows across southern Tibet to break through the Himalayas in great gorges and into Arunachal Pradesh where it is known as Dihang. It flows southwest through the Assam Valley as Brahmaputra and south through Bangladesh as the Jamuna. There it merges with the Ganges to form a vast delta. About 1,800 miles (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. The average depth of river is 124 feet (38 m) and maximum depth is 380 feet (120 m). In Bangladesh the river merges with the Ganges 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 mangroves. 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 part 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.
Deepest Canyon [02.27.09]
The Yarlung Tsangpo originates in the Jima Yangzong glacier near Mount Kailash in the northern Himalayas. It then flows east for about 1,700 kilometres (1,100 mi), at an average height of 4,000 metres (13,000 ft), 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.
In India [02.26.09]
As the river enters Arunachal Pradesh, it is called Siang and makes a very rapid descent from its original height in Tibet, and finally appears in the plains, where it is called Dihang. It flows for about 35 kilometres (22 mi) 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 kilometres (6.2 mi). Between Dibrugarh and Lakhimpur districts the river divides into two channels---the northern Kherxhutia channel and the southern Brahmaputra channel. The two channels join again about 100 kilometres (62 mi) downstream forming the Majuli island. At Guwahati near the ancient pilgrimage center of Hajo, the Brahmaputra cuts through the rocks of the Shillong Plateau, and is at its narrowest at 1 kilometre (1,100 yd) 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 Lauhitya and the local name in Assam is Luit. The native inhabitants, i.e., the Bodos called the river Bhullam-buthur, which means 'making a gurgling sound,' later Sanskritized into Brahmaputra.
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.
