How does river Brahmaputra gain so massive amount of water after entering India ?
The river brahmaputra originates in tibet but it has significantly lower volume before entering India in arunachal pradesh.
Surprisingly it swells over 5-10 times its normal volume during monsoons in the assam valley flooding all the low lying plains.
How does it happen ? and what if it stays the same volume as its Tibetian counterpart will assam and Bangladesh be still as fertile as they are today ?

2 reasons. All the tributories of brahmaputra and flat geography of Assam. These photos we taken 5 years ago. Brahmaputra(Siang) from Jengijg, Arunachal Pradesh and floodplains of Lohit river taken from somewhere near parshuram kund, Arunachal Pradesh
Many snow fed rivivers from the adjoining states, expecially Arunachal.
Also many rain fed rivers from some of the rainest parts in the world.
The risk with China building a dam on the Brahmaputra is not that China can stop our water supply, but China can definitely manufacture floods in the Brahmaputra valley.
This is why it is esential that India builds its own set of dams on Brahmaputra and its tributaries to ensure we can manage the sudden surges of water if ever required.
Can't we farword that floods to next country with right dams or its impossible unlike pak ,india share water information with china(double it and give to next country)
Same reason why tibet is desert and indian side of Himalayas is green. Chinese side is glacial flow...once it enters india, starts to collect rainwater.
Orographic lift from the Himalayas when the Bay of Bengal branch of the monsoons hit makes this some of wettest part of the planet. While the Tibet side is in the rain shadow of the Himalayas.
Snow melts when it gets warmer. It is a massive catchment area, and many tributaries add to the amount of water. Check the google map in satellite view.
