Brahmaputra & Indus River Systems GK Questions & Answers
The Indus and Brahmaputra river systems represent two trans-Himalayan drainage networks originating in the Tibetan Plateau near Lake Manasarovar. The Brahmaputra originates from the Chemayungdung Glacier as the Yarlung Tsangpo, flowing eastward for 1,100 kilometres before carving the deep Dihang Gorge around the Namcha Barwa peak (7,782 metres). Entering Arunachal Pradesh as the Siang, it merges with the Dibang and Lohit to form the Brahmaputra in the Assam Valley, where extensive braiding creates Majuli, the world's largest inhabited riverine island. Major tributaries include the Subansiri, Kameng, Manas, and Teesta. Conversely, the Indus originates from the Bokhar Chu glacier (Singi Khamban) at 4,164 metres, flowing northwest through Ladakh between the Karakoram and Zanskar ranges before turning southward into Pakistan. Its major Himalayan tributaries include the Shyok, Gilgit, and Zanskar, along with the five Punjab rivers: Jhelum, Chenab (the largest tributary formed by the Chandra and Bhaga), Ravi, Beas, and Sutlej. Cross-border water sharing is regulated under the historic Indus Waters Treaty of September 19, 1960, brokered by the World Bank, allocating eastern rivers to India and western rivers to Pakistan.

The Brahmaputra originates from Chemayungdung Glacier as the Yarlung Tsangpo, bends around Namcha Barwa, and forms Majuli island in the Assam Valley.
Key tributaries of the Brahmaputra include the Subansiri, Kameng, Manas, Teesta on the north bank, and the Dibang, Lohit, and Dhansiri on the south bank.
The Indus originates at the Bokhar Chu glacier in Tibet and flows across Ladakh before traversing Pakistan to discharge into the Arabian Sea.
The five principal tributaries of the Indus are the Jhelum, Chenab (its largest tributary), Ravi, Beas (entirely in India), and Sutlej (originating at Rakas Lake).
The Indus Waters Treaty of 1960 allocates the Eastern Rivers (Ravi, Beas, Sutlej) to India and the Western Rivers (Indus, Jhelum, Chenab) to Pakistan.
