Identifying Rivers Not Flowing in Pakistan

The question asks to identify which river among the given options does not flow through Pakistan. Pakistan's major rivers are part of the larger Indus River system. Let's examine the flow of each river listed:

Indus River System Tributaries

The Indus River system includes its major tributaries, which are crucial for the water supply in Pakistan. The five main tributaries are Jhelum, Chenab, Ravi, Beas, and Sutlej (Satluj). These rivers mostly originate in the Himalayas (India) and flow into Pakistan, eventually merging into the Indus River.

Analysis of River Flows

• Satluj River: This river originates in Tibet, flows through India (Himachal Pradesh and Punjab), and then enters Pakistan, where it merges with the Chenab River to form the Panjnad River, a tributary of the Indus River. So, Satluj flows in Pakistan.
• Jhelum River: Originating in the Kashmir Valley (India), the Jhelum River flows through Pakistan-administered Kashmir and then into Punjab province in Pakistan, where it joins the Chenab River. So, Jhelum flows in Pakistan.
• Chenab River: Formed by the confluence of the Jhelum and Ravi rivers in Pakistan (or upstream in India depending on definition), the Chenab River flows through Punjab province in Pakistan before meeting the Sutlej River. So, Chenab flows in Pakistan.
• Ravi River: Originating in the Himalayas in India, the Ravi River flows through Punjab, India, and then enters Pakistan, flowing through Punjab province before joining the Chenab River. So, Ravi flows in Pakistan.
• Beas River: The Beas River originates and flows entirely within the Indian states of Himachal Pradesh and Punjab. It is a unique river among these options because it does not enter Pakistan. The Beas merges with the Satluj River in the state of Punjab, India.

Conclusion

Based on the analysis, the Beas River is the only river listed that flows entirely within India and does not flow through Pakistan. It is a tributary that joins the Satluj River within India before the Satluj enters Pakistan.
