Answer 1

• Source: The Brahmaputra rises in Tibet east of Mansarowar lake very close to the sources of the Indus and the Satluj.

• Tributaries of Brahmaputra:
→ Dibang, the Lohit

• Flows eastwards parallel to the Himalayas. it takes a ‘U’ turn on reaching the Namcha Barwa and enters India in Arunachal Pradesh through a gorge.
→ Here, it is called the Dihang and it is joined by the Dibang, the Lohit and many other tributaries.

• In Tibet the river carries a smaller volume of water and less silt as it is a cold and a dry area.
→ In India it passes through a region of high rainfall. and the river carries a large volume of water and considerable amount of silt

• It forms many riverine islands.

• Every year during the rainy season, the river overflows its banks, causing widespread devastation due to floods in Assam and Bangladesh.
