Luni River: Origin, Tributaries, Basin, Dams and Concerns

Luni River:

Luni is a major west-flowing river that originates from western slopes of Naga hills, at an elevation of 772 m in Ajmer district of Rajasthan, where it is known as the Sagarmati.  After passing Govindgarh, it meets its tributary Sarsuti, which originates from Pushkar Lake, and from then on it is referred to as Luni River.

The name Luni is derived from the Sanskrit word lavanavari (“salt river”) and is so called because of its excessive salinity. The Luni river is not saline until it reaches Balotra, where high salt content in the soil impacts the river.

Luni Course:

Luni River originates in Naga Hills of Aravalli Range, near Pushkar valley in Ajmer district. At Govindgarh it meets its tributary Sarsuti and travels in north-western direction towards Nagaur. Luni takes a turn and starts flowing in southwest direction through the aravalli hills in Pali and reaches plains of marwar region in Jodhpur.  It continues in the same direction into Barmer and Jalore, eventually discharging into  Rann of Kachchh, Gujarat. At Rann of Kutch, Luni forms a delta where the water spreads out and does not contribute any runoff.

The total length of Luni is about 511 kms.

Luni Basin:

  • The Luni basin is bounded by Aravalli range and Gujarat plains on the east, by Rajasthan desert on north, and by the Arabian Sea on the south and the west.
  • The total area of Luni basin is 32,879 Sq.km and includes several parts of the Ajmer region from Nagaur to Pali and then moving towards Jodhpur and Barmer before its entry into the Jalore district.
