Inland Drainage
Inland Drainage is a river or stream that does not reach up to the sea and constitutes inland drainage.
These rivers are mostly present in the drier regions of the country like Western Rajasthan, Ladakh and Aksai Chin etc.
Luni River
Luni River also known as the Salt River (Lonari or Lavanavari in Sanskrit) is named so because its water is brackish below Balotra.
Its source lies to the west of Ajmer in the Aravalli range, Rajasthan.
It is the only river basin of any significance in Western Rajasthan, which forms the bulk of the arid zone.
