RAS question
Ruparel (Rupnarayan) River flows through which districts?
Correct answer: (D) Alwar, Bharatpur.
The Ruparel, also known as the Ruparail or Rupnarayan River, flows through Alwar and Bharatpur districts of Rajasthan.
Explanation
Ruparel belongs to the north-eastern Rajasthan drainage pattern. The cited Rajasthan groundwater atlas places the Ruparail River Basin over parts of Alwar and Bharatpur districts. It says the river rises in the Udainath hills of Thanagazi Reserved Forest in Alwar district, then moves northwards, turns east and north-east, and disappears in Bharatpur district. That matches the standard exam explanation: the river originates in the Alwar hills around Thanagazi, flows through Alwar and Bharatpur, and ends in wetland-like low-lying terrain rather than joining a major external river system. Therefore, the district pair asked in the question is Alwar and Bharatpur.
Why the other options are wrong
- (A) Kota and Bundi point to the Hadoti region, while the cited Ruparail basin is in north-eastern Rajasthan and extends over Alwar and Bharatpur.
- (B) Udaipur and Bhilwara are not supported by the source, which traces the river from Thanagazi in Alwar towards Bharatpur.
- (C) Ajmer and Tonk are a central Rajasthan pairing, but the verified basin description places Ruparail in Alwar and Bharatpur districts.
Concept
This tests Rajasthan's inland drainage and district-wise river mapping. RAS repeatedly asks such questions because small river systems are best identified by origin, flow direction and terminal lowland rather than by length alone.
