RAS question

Ahu River is a tributary of which river?

Correct answer: (B) Kali Sindh.

The Ahu River is a tributary of the Kali Sindh River.

  1. (A)

    Banas

  2. (B)

    Kali Sindh

  3. (C)

    Mahi

  4. (D)

    Chambal

Explanation

Ahu is counted as a tributary of the Kali Sindh because its course ends by merging with the Kali Sindh River. Wikipedia lists the river mouth as the Kali Sindh River and describes the Ahu's course as eventually finding its way to the Kali Sindh. The Ahu flows through Jhalawar district and is an important river of the Hadoti region. Ahu contributes to the immediate Kali Sindh river system rather than only to the wider drainage chain. Since Ahu directly joins the Kali Sindh, the Kali Sindh is the precise river relationship.

Why the other options are wrong

  • (A) Banas is wrong because Ahu contributes to the Kali Sindh, not to Banas.
  • (C) Mahi is wrong because Ahu is not placed in the Mahi river system.
  • (D) Chambal is not the direct river relationship because Ahu's tributary relationship is with the Kali Sindh, and Ahu's mouth is the Kali Sindh River.

Concept

Rajasthan drainage geography includes the tributary relationships of Hadoti rivers. RAS preparation often links river systems in physical geography with district-level map knowledge.
