If we consider the total distance covered by a river in India, then the Ganges is the longest river in India. The two major rivers of the Indian subcontinent – Brahmaputra and Indus, though are much longer than the Ganges, but the distance of these two rivers in India is very less compared to the Ganga.
In India, the length of Ganga river is longer than the Indus River and the Brahmaputra River in India. This is because the Ganges River originates in Gangotri Glacier, which is situated in India. It originates from Uttarakhand, which is in India; hence, it becomes the longest river of India.
If we talk about the Indus River then it becomes the longest river in the India because it has a length of 2900 km, which has its origins in the place of Sinn in Tibet while the length of the Brahmaputra river is 2700 km, which has its origin in Tibet, it is from the Chemayung Dung of Tibet.
Whereas the length of river Ganges is 2,525 km, so in the case of river Ganges, the river is smaller than the Indus River and the Brahmaputra River. But if we consider the total distance covered by a river in India, then the Ganges is India’s longest river. Let’s know in brief about the longest river of India.
