Question

is it for for Siang Lower Project ???????????

Answer 1

As the river enters Arunachal Pradesh, it is called Siang and makes a very rapid descend from its original height in Tibet, and finally appears in the plains, where it is 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 Kherxhutia 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-***-road bridge across the Brahmaputra was opened to traffic in April 1962 at Saraighat.
