Correct option is D
Correct Answer: Luni
Explanation:
- The Luni River is an ephemeral river, meaning it flows only during the monsoon season and remains dry for most of the year.
- It originates in the Pushkar Valley of the Aravalli range in Rajasthan and flows through the Thar Desert before dissipating into the marshy lands of Gujarat.
- Due to its location in an arid region, the Luni River's flow is heavily dependent on rainfall. It carries high salinity, making its water unsuitable for drinking or irrigation in most parts.
Information Booster:
- Ephemeral rivers flow only during specific seasons, usually after heavy rainfall.
- The Luni River is also known as the "Sagarmati" in its early course.
- Unlike perennial rivers, ephemeral rivers do not have a consistent water supply throughout the year.
- Other ephemeral rivers in India include Ghaggar and Saraswati (in their modern forms).
