Which of the following rivers is ephemeral?
Beas
Chambal
Yamuna
Luni
Luni
An ephemeral river is one that flows only periodically, typically during and immediately after heavy rainfall. The Luni river in Rajasthan is known for this characteristic as it originates in the Aravalli range and disappears into the Rann of Kutch marshlands without reaching the sea, frequently drying up in the arid Thar Desert region.

The Luni river in Rajasthan is known for this characteristic as it originates in the Aravalli range and disappears into the Rann of Kutch marshlands without reaching the sea, frequently drying up in the arid Thar Desert region.
Geography of India: The Luni is a classic example of an inland drainage system where river channels terminate in salt lakes or deserts rather than the ocean.
Luni is an endorheic river originating near Ajmer in the Aravalli range.
It flows through the semi-arid regions of Rajasthan and Gujarat.
The river exhibits high salinity downstream due to the high mineral content of the desert soil.
Option A (Beas): A perennial tributary of the Indus river system, originating in the Himalayas.
Option B (Chambal): A perennial river and the largest tributary of the Yamuna, famous for its badland topography.
Option C (Yamuna): A perennial river, the largest tributary of the Ganga, fed by Himalayan glaciers.
The Luni becomes saline after crossing Balotra in the Barmer district of Rajasthan.
D is correct тАФ The Luni is an ephemeral river that flows only during the monsoon and terminates in the inland Rann of Kutch.
When studying drainage patterns, remember that Himalayan rivers are perennial (glacial fed), whereas Peninsular/Desert rivers are often rain-fed and can be seasonal or ephemeral.
