UPSC Prelims 2021 Question:

Consider the following rivers:

  1. Brahmani
  2. Nagavali
  3. Subarnarekha
  4. Vamsadhara

Which of the above rise from the Eastern Ghats?

  1. 1. 1 and 2
  2. 2. 2 and 4
  3. 3. 3 and 4
  4. 4. 1 and 3

Answer (Detailed Solution Below)

Detailed Solution

Explanation: 

  • Brahmani River: This river is formed by the confluence of the Sankh and South Koel rivers. Both of these rivers originate in Chota Nagpur Plateau. It is one of the few rivers that cut across the Eastern Ghats (not rise from the Eastern Ghats). So, point 1 is not correct.

  • Nagavali River: It is the prime river of Odisha and Andhra Pradesh and originates in the eastern hills of Eastern Ghats in Odisha. Nagavali River is also known as Langulya.  So, point 2 is correct.

  • Subarnarekha River: It rises near Nagri village in the Ranchi (Not in the Eastern Ghat) District of Jharkhand. The Subarnarekha (meaning “Streak of Gold”) flows east through a copper-mining region and leaves the Chota Nagpur plateau by the Hundrugbagh waterfall. So, point 3 is not correct.

  • Vamsadhara River: It is an important east flowing river between Rushikulya and Godavari, in Odisha and Andhra Pradesh states in India. Vamsadhara river rises in the Eastern Ghats in Odisha. So, point 4 is correct.


Therefore, option (2) is the correct answer.
