    What are the main characteristics of the mighty river Brahmaputra?

    Answer:

    (i) The Brahmaputra rises in Tibet east of Mansarovar Lake very close to the sources of the Indus and the Satluj. (ii) It is slightly longer than the Indus and most of its course lies outside India. (iii) In Tibet, the river carries a smaller volume of water and less silt as it is a cold and a dry area. (iv) In India, it passes through a region of high rainfall. Here the river carries a large volume of water and considerable amount of silt. (v) The Brahmaputra has a braided channel in its entire length in Assam and forms many riverine islands. (vi) Every year during the rainy season, the river overflows its banks causing widespread devastation due to floods in Assam and Bangladesh. (vii) Unlike other north Indian rivers, the Brahmaputra is marked by huge deposits of silt on its bed causing the river bed to rise. The river also shifts its channel frequently.
