RAS question
Which river originates from Gogunda Hills?
Correct answer: (D) Berach.
The Berach River originates from the Gogunda hills in Udaipur district, Rajasthan.
Explanation
The river asked about is Berach. Its source is in the Gogunda Hills near Udaipur; it flows through Udaipur and Bhilwara, and joins the Banas near Bigod. Discover Water, Springer Nature identifies the Berach-Banas catchment and states that the Berach River originates from the Gogunda hills in Udaipur district. This also explains why Banas is a tempting but wrong option: the Banas source is at Veron ka Math in the Khamnor Hills of the Aravalli Range, not at Gogunda. For RAS, the examiner is testing exact river-source mapping, not just broad familiarity with southern Rajasthan's drainage.
Why the other options are wrong
- (A) Chambal is wrong because its source is Janapav, whereas the question asks for the river from Gogunda Hills.
- (B) Luni is wrong because its source is Nag Pahar, not in the Gogunda Hills.
- (C) Banas is wrong because its source is at Veron ka Math in the Khamnor Hills, and it does not originate from Gogunda.
Concept
This tests Rajasthan drainage geography, especially source regions and river linkages in the Aravalli belt. It recurs in RAS because river-origin questions are compact factual checks that distinguish nearby but different systems such as Berach, Banas, Luni and Chambal.
