Which one among the following is not a tributary of river Luni?
- A.Khari
- B.Sukri
- C.Jawai
- D.Banas
Correct answer
Explanation
The correct answer is D, Banas. The Banas is not a tributary of the Luni; it flows east and joins the Chambal, which belongs to the Ganga basin. The Luni rises near Ajmer in the Aravalli hills and flows south-west across western Rajasthan before ending in the Rann of Kachchh in Gujarat. It is an inland river of the Thar region and its water turns salty below Balotra. Its main tributaries come from the western slopes of the Aravallis and join it from the left: the Sukri, the Jawai, the Khari, the Mithri, the Bandi and the Sagi, while the Jojri joins from the right. The Banas, by contrast, rises in the Aravallis near Kumbhalgarh and drains the eastern side of the range, joining the Chambal in Sawai Madhopur district. Option A is wrong because the Khari is a left-bank tributary of the Luni. Option B is wrong because the Sukri joins the Luni from the left. Option C is wrong because the Jawai, on which the Jawai dam stands, is also a Luni tributary. Exam tip: Luni goes to the Rann of Kachchh with Sukri, Jawai and Khari; Banas goes to the Chambal.
