The Ghaggar River is an intermittent river that flows in India and Pakistan. The river flows only during the monsoon season. It rises from the Shivalik Range
of northwestern Himachal Pradesh
. The river then 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. This seasonal river feeds two irrigation canals that extend into Rajasthan. The Hakra, which flows in Pakistan, is the continuation of the Ghaggar River
in India and they are together called the Ghaggar - Hakra River. Several historians identify Ghaggar with the Vedic Saraswati River. Along the banks of the Ghaggar River many settlements of Indus Valley Civilization have been excavated.
