Description:
The identity of the river along which the famous
Harappan Civilization developed and the causes of the
demise of this culture are topics of considerable debate.
Many of the Harappan sites are located along
the ephemeral Ghaggar river within the Thar Desert
in the northwestern India and adjacent Pakistan. The
Ghaggar was also thought to be the mythical river
Saraswati, which was described as glacial-fed river. Sr
and Nd isotopic composition of the Ghaggar alluvium
as well as Thar Desert sediments suggests a Sub-Himalayan
sediment source, with no contribution from the
glaciated regions. The development of extensive
Harappan Civilization all along the Ghaggar suggests
a catchment with high monsoon rainfall. It is likely
that with the changes in the monsoon scenario after
3500 BC could have gradually dried up the Ghaggar
river and resulted in the migration and/or extinction
of the Harappan Civilization on this river.
