Luni River Basin is located in south-western Rajasthan, between
latitudes 23o41' and 27o05' and longitudes 71o04' and 74o42'. It
is bounded by the arid western districts (The Outside Basins) in
the west, by Banas Basin in the east, Shekhawati Basin in the north,
and Sukli and West Banas Basins in the south.
The Basin extends over parts of Ajmer, Barmer, Jalore, Jodhpur,
Nagaur, Pali, Rajsamand, Sirohi and Udaipur Districts.
The total catchment area of the Basin is 37,363 km2 according to
the 1:250,000 scale topographical maps published by the Survey of
Luni River Basin lies to the west of the Aravali hills and forms
part of the mid-west alluvial plain. Orographically, the eastern
part of the Basin is marked by hilly terrain belonging to the Aravali
chain. West of the hills lies a narrow alluvial plain which gently
slopes westwards. Luni River originates in Ajmer and flows to the
Rann of Kutch in Gujarat State.
River Luni originates in the western slopes of the Aravali range
at an elevation of 550 m, near Ajmer. After flowing for about 495
km in a south-westerly direction in Rajasthan, the river disappears
in the marshy land of Runn of Kutch.
The water of River Luni is sweet up to Balotra and becomes more
and more saline further downstream. The main tributaries of Luni
on the left are Sukri, Mithri, Bandi, Khari, Jawai, Guhiya and Sagi,
whereas only Jojari river joins it on the right side.
The mean annual rainfall over the Luni Basin was computed as 320
mm, of which about 97% falls during the four Monsoon months (June-September).
4. Existing Surface water Projects
There are 2 Major (Sardar Samand and Jawai dam), 9 Medium and 344
Minor irrigation projects in the Luni River Basin, as well as some
small irrigation systems (covering less than 20 ha) constructed
and operated by Panchayat Samities (PS).
5. Ongoing Surface Water Projects
4 irrigation projects, with a total live storage capacity of 11
Mm3, are under construction in the Luni Basin. An additional area
of 2514 ha will be irrigated on completion of these projects.
6. Proposed Surface Water Projects
25 irrigation projects, with a total live storage capacity of 57
Mm3, have been proposed by the ID in this Basin. An additional area
of 8399 ha will be irrigated on completion of these projects.
