RAS question
Parwan Multipurpose Dam Project is on which river?
Correct answer: (C) Parwan.
The Parwan Multipurpose Dam Project is on the Parwan River in Rajasthan.
Explanation
Parwan Multipurpose Dam is identified with the Parwan River, not with the larger rivers in the basin. The CWC Annual Report 2021-22 describes the Rajasthan Parwan Dam Project as having a 38 m high concrete dam on the river Parwan, and also notes that Parwan is a tributary of the Kalisindh, which is itself a main tributary of the Chambal. This makes the river asked in the MCQ clear: the project is on Parwan. The dam is in Jhalawar district, and the project combines irrigation and hydropower objectives, so the name of the project and the river are directly aligned.
Why the other options are wrong
- (A) Chambal is the larger basin river, but the CWC report places the dam on the river Parwan, with Parwan only linked to Chambal through the Kalisindh tributary system.
- (B) Kalisindh is related to the project only because Parwan is its tributary; the dam itself is stated to be on the river Parwan.
- (D) Banas is not part of the Parwan project description and is associated with Bisalpur rather than Parwan Multipurpose Dam.
Concept
This tests Rajasthan river-valley project mapping: matching a dam or multipurpose project with its exact river. It recurs in RAS because irrigation, hydropower and drainage-basin facts are asked as direct location-based geography.
