Q. Consider the following statements about the Brahmaputra River system in Assam:

1. The Brahmaputra has one of the highest specific discharge rates among major Indian rivers.
2. Frequent channel migration of the Brahmaputra is largely influenced by tectonic activity in the region.
3. Embankments have completely eliminated flood hazards in Assam.

Which of the statements given above are correct?

A. 1 and 2 only
B. 2 only
C. 1 and 3 only
D. 1, 2 and 3

View Answer
Answer: 1 and 2 only
Explanation: Statements 1 and 2 are correct.

The Brahmaputra records very high discharge due to heavy rainfall and glacier-fed tributaries. The region is tectonically active, which alters river gradient and promotes channel shifting. Embankments have reduced but not eliminated flood hazards.
