This is detail about GANGA BASIN.
It is the largest basin in India with area about 861452 sq. km. It originates from the Gangotri glacier in Himalaya and traverses about 2,525 km across the states of Uttarakhand, Uttar Pradesh, Bihar, Jharkhand and West Bengal before falling into the Bay of Bengal. Its principal tributaries are Yamuna, Chambal, Banas, Kali Sindh, Parbati, Sind, Betwa, Dhasan, Keri, Gomti, Sarda, Ghaghara, Gandak, Son, Damodar, and Hooghly, Ramganga, and Mahananda.

Reasoning:
The Brahamaputra basin has the largest run-off in India due to various factors such as the size of the basin, the amount of rainfall it receives, and the topography of the region.
Factors contributing to the large run-off in the Brahamaputra basin:
- Size of the basin: The Brahamaputra basin is one of the largest river basins in India, covering a vast area in the northeastern part of the country. This large size allows for a significant amount of water to flow through the basin, resulting in a high run-off.
- Amount of rainfall: The Brahamaputra basin receives heavy rainfall throughout the year, especially during the monsoon season. This abundant rainfall contributes to a large volume of water flowing through the basin, increasing the run-off.
- Topography of the region: The Brahamaputra basin is characterized by steep slopes and high mountains, which facilitate rapid drainage of water into the river. This topography accelerates the flow of water through the basin, leading to a higher run-off compared to other river basins in India.
Conclusion:
In conclusion, the Brahamaputra basin has the largest run-off in India due to its large size, abundant rainfall, and the topography of the region. These factors combine to make it a significant contributor to the overall water resources in the country.
