The correct answer is c) Both 1 and 2.
The Brahmaputra River is prone to flooding in India because it passes through a region with high rainfall, which can contribute to the river rising and flooding. Additionally, the Brahmaputra has huge deposits of silt on its bed, which can also cause the river bed to rise and lead to flooding. In contrast, Tibet is a dry, cold region with lower levels of rainfall, which can help to prevent the river from flooding.

Introduction:
The Brahmaputra River, one of the major rivers in Asia, flows through both India and Tibet. While it experiences frequent flooding in India, it remains unaffected by floods in Tibet. This difference can be attributed to two main causes.
1. Regional Difference in Rainfall:
The first reason for the flooding of the Brahmaputra River in India and not in Tibet is the significant difference in rainfall patterns between the two regions.
- In India, the Brahmaputra River passes through a region of high rainfall, particularly in the states of Assam and Arunachal Pradesh. These areas receive heavy monsoon rains due to their proximity to the Bay of Bengal and the Himalayan range.
- The monsoon rains, combined with the steep slopes of the Himalayas, lead to a high volume of water flowing into the Brahmaputra River, causing it to swell and flood its banks.
- In contrast, Tibet is a dry and cold region with limited rainfall. The Brahmaputra River originates from the Angsi Glacier in Tibet, where the precipitation is much lower compared to the downstream regions in India. The lack of heavy rainfall in Tibet reduces the chances of flooding along the river.
2. Silt Deposits and River Bed Elevation:
Another reason for the flooding of the Brahmaputra River in India is the accumulation of silt deposits on its bed.
- The Brahmaputra River carries a substantial amount of sediment, primarily due to the erosion of the Himalayan mountains. This sediment consists of rocks, sand, and silt particles, which are transported downstream by the river.
- As the river reaches the plains of India, the speed of water decreases, leading to the deposition of these sediments. Over time, this continuous deposition raises the river bed.
- The elevated river bed reduces the carrying capacity of the river, making it more prone to flooding. During heavy rainfall, the excess water is unable to flow efficiently within the constrained channel, resulting in the overflow of water and flooding of nearby areas.
Conclusion:
The frequent flooding of the Brahmaputra River in India, but not in Tibet, can be attributed to the regional difference in rainfall patterns and the presence of silt deposits on its bed. While India receives heavy monsoon rains and experiences sediment deposition, Tibet remains relatively dry and lacks the same level of sediment accumulation. Understanding these causes is crucial for effective flood management and mitigation strategies in the affected regions.
