RAS question
Gambhir River (of Bharatpur) flows into which wetland?
Correct answer: (C) Keoladeo Ghana.
The Gambhir River of Bharatpur feeds Keoladeo Ghana, the wetland landscape of Keoladeo National Park.
Explanation
Keoladeo Ghana is correct because the official eco-sensitive zone notification places Keoladeo National Park in Bharatpur district at the confluence of the Gambhir and Banganga rivers. The park is locally known as Ghana and consists of a mosaic of grasslands, woodlands, woodland swamps and wetlands. The Bharatpur stretch of the Gambhir is therefore tied directly to the Keoladeo Ghana wetland landscape. This geographical link matters because Keoladeo is a wetland of national and international importance and provides habitat for many migratory and native birds. The river is not an isolated drainage fact; it belongs to the hydrology that sustains the Keoladeo Ghana wetland habitat.
Why the other options are wrong
- (A) Chambal is a river system, not the Bharatpur wetland formed around the Gambhir-linked Keoladeo National Park landscape.
- (B) Sambhar Lake is a separate saline lake system, whereas the relevant Gambhir-linked wetland is Keoladeo Ghana in Bharatpur district.
- (D) Yamuna is the eventual river-system destination because Gambhir and Banganga are tributaries of the Yamuna, but Keoladeo Ghana is the wetland habitat associated with Bharatpur's Gambhir-Banganga setting.
Concept
This tests Rajasthan drainage and wetland geography, especially how river systems support protected wetland habitats. It recurs in RAS because Bharatpur's Keoladeo Ghana connects physical geography, ecology and conservation in one standard map-based fact.
