Understanding Rivers Flowing Through Asia

This question asks us to identify a major river that traverses three significant regions: Tibet (part of China), India, and Bangladesh. Let's examine the flow path of each river provided in the options.

Analyzing the River Options

• Brahmaputra: This river originates in the Himalayas in Tibet, flows eastwards through Tibet (known as Yarlung Tsangpo), enters India in Arunachal Pradesh, flows through Assam, and then enters Bangladesh, finally merging with the Ganges (Padma) before emptying into the Bay of Bengal. This path covers all three regions: Tibet, India, and Bangladesh.
• Yamuna: A major tributary of the Ganges, the Yamuna river originates in the Yamunotri Glacier in the lower Himalayas in India and flows entirely within India before merging with the Ganges at Allahabad (Prayagraj). It does not flow through Tibet or Bangladesh.
• Narmada: This is a major river in central India, flowing westwards into the Arabian Sea. It originates in the Amarkantak Plateau in Madhya Pradesh and flows primarily through the states of Madhya Pradesh, Maharashtra, and Gujarat in India. It does not flow through Tibet or Bangladesh.
• Ganga: The Ganges (Ganga) river originates in the Gangotri Glacier in the Himalayas in India. It flows through northern India and then enters Bangladesh (where it is known as the Padma), eventually joining the Brahmaputra (Jamuna in Bangladesh) and Meghna rivers to form the world's largest delta before flowing into the Bay of Bengal. While it flows through India and Bangladesh, its primary source is in India, not Tibet, although its tributaries might originate in the Himalayas near the border. However, the main stem flowing through Tibet is the Brahmaputra.

Identifying the Correct River

Based on the analysis of the flow paths:

• The Yamuna flows only in India.
• The Narmada flows only in India.
• The Ganga flows through India and Bangladesh, but not Tibet in its main course.
• The Brahmaputra originates in Tibet, flows through India, and then enters Bangladesh.

Therefore, the Brahmaputra is the river that flows through Tibet, India, and Bangladesh.

The river that fits the description of flowing through Tibet, India, and Bangladesh is the Brahmaputra.

Additional Information: The Brahmaputra River System

The Brahmaputra River is one of the major rivers of Asia. It has significant cultural and economic importance in the regions it flows through.

• Names: It is known as Yarlung Tsangpo in Tibet, Siang/Dihang in Arunachal Pradesh, Brahmaputra in Assam, and Jamuna in Bangladesh.
• Origin: It originates from the Chemayungdung Glacier, located south-west of Mount Kailash in the Himalayas in Tibet.
• Course: After flowing east through Tibet, it makes a sharp southward bend and enters India. It flows through Arunachal Pradesh and Assam before entering Bangladesh.
• Tributaries: Key tributaries include Subansiri, Manas, Teesta, Lohit, and Dhansiri.
• Importance: The river is crucial for irrigation, navigation, and hydropower generation. However, it is also known for its frequent and devastating floods, especially during the monsoon season.
