The Ganga is the longest river of India. Brahmaputra is longer than Ganga but a little part of it is situated in India.But the whole part of Ganga is situated in India.So the longest river of India is Ganga.

The longest river in India is the Brahmaputra. Let's explore why the Brahmaputra holds this distinction.

The Brahmaputra River
The Brahmaputra River is one of the major rivers in Asia and the longest river in India. It flows through Tibet, China, India, and Bangladesh, covering a total distance of approximately 2,900 kilometers. In India, it flows through the northeastern states of Arunachal Pradesh and Assam.

Origin and Course
The Brahmaputra River originates from the Mansarovar Lake in the Tibetan plateau. It is known as the Yarlung Tsangpo River in Tibet. The river then flows eastward through the Himalayas, forming the world's deepest and longest canyon, the Yarlung Tsangpo Grand Canyon, before entering India.

Course in India
In India, the Brahmaputra River enters through Arunachal Pradesh and is known as the Siang River. It flows through the state, receiving various tributaries along the way, such as the Dibang, Lohit, and Subansiri rivers.

Confluence with Ganga River
After flowing through Arunachal Pradesh, the Brahmaputra River enters Assam and is joined by the Subansiri River. It then continues its journey southward, forming the border between India and Bangladesh for a significant distance. Finally, it merges with the Ganga River (known as the Padma River in Bangladesh) near the Sundarbans Delta, eventually emptying into the Bay of Bengal.

Importance and Significance
The Brahmaputra River is of great significance to the region it passes through. It is a lifeline for millions of people, providing water for irrigation, transportation, and various other activities. It is also a vital ecosystem supporting diverse flora and fauna.

Flooding and Erosion
The Brahmaputra River is known for its unpredictable nature. It often causes devastating floods and erosion in the areas it passes through, particularly in Assam. The river's high sediment load, combined with heavy rainfall in the region, contributes to these natural hazards.

Conclusion
To summarize, the Brahmaputra River is the longest river in India. It originates in Tibet, flows through Arunachal Pradesh and Assam, and eventually merges with the Ganga River in Bangladesh. Its course covers a vast distance and plays a crucial role in the lives of those living along its banks.
