Ghaggar is a seasonal river of north India. It rises from the Shivalik Range of north-western Himachal Pradesh and flows through
Pinjore in Haryana to meet River Saraswati. After passing through Ambala and Hissar districts of Haryana it disappears into the Thar Desert in Rajasthan. The seasonal flow of the river is maintained by the monsoon rain. Several scholars identify Ghaggar with the Vedic Saraswati River. Many settlements of Indus Valley Civilization have been excavated along the banks of Ghaggar.
