Question

Why does Brahmaputra carry less water in tibet?

Answer 1

The Brahmaputra in its Tibetan part has less slit,dispite a longer course bcoz in Tibet the river carries a smaller volume of water and less slit as it is cold and a dry area and the erosional capacity of the river is low.

Answer 2

As Tibet is a cold and dry area,the Brahmaputhra river carries less silt and smaller volume of water.When the river enters India through Arunachal Pradesh,it passes through a region of high rainfall.Here the river carries a large volume of water and a considerable amount of silt.
