- 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. Here the river carries a large volume of water and considerable amount of silt.
- Every year during the rainy season, the river overflows its banks, causing widespread devastation due to floods in Assam and Bangladesh. 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.

Reasons for the flooding of the Brahmaputra River in India, but not in Tibet:
There are two main reasons for the flooding of the Brahmaputra River in India, while it remains relatively unaffected in Tibet:
1. Volume of water and silt:
- In Tibet, the Brahmaputra River carries a smaller volume of water and less silt. This is because Tibet is a cold and dry area, with less rainfall and snowmelt compared to the downstream areas in India. As a result, the river in Tibet has a lower flow rate and carries less sediment.
- In contrast, the river accumulates a significant amount of water and sediment as it flows through the Indian states of Arunachal Pradesh, Assam, and Bangladesh. The heavy monsoon rains in these regions, combined with the melting of snow from the Himalayas, contribute to a much larger volume of water and silt being carried by the river.
2. Deposits of silt:
- The Brahmaputra River in India is marked by huge deposits of silt on its bed. Over time, the continuous deposition of silt causes the river bed to rise, reducing its capacity to hold water. This leads to frequent flooding during periods of heavy rainfall or snowmelt.
- In Tibet, however, the smaller volume of water and silt prevents significant accumulation of sediment on the river bed. As a result, the river in Tibet maintains a relatively stable channel capacity, reducing the likelihood of flooding.
Conclusion:
In conclusion, the Brahmaputra River experiences frequent flooding in India but not in Tibet due to the higher volume of water and silt carried by the river in India, as well as the deposition of silt on its bed. The differences in climate, rainfall, and topography between Tibet and the downstream regions contribute to these variations in the behavior of the river.
