Bangalore, May 5: Unveiling the mystery of ancient river Saraswati, which many
archaeologists believe had vanished, remote sensing experts reveal that the
present day river Ghaggar in northern Rajasthan was the main course of the Vedic
river.
Utilising remote sensing data obtained from IRS satellites, experts at the
regional remote sensing service centre in Jodhpur have plotted the drainage of
the river Saraswati, according to Isro.
The experts said the river further flowed to Rann of Kutch and a channel of the
main river course passed through Jaisalmer district while a major part of the
river was drained further west inside Pakistan.
According to Isro sources a team of experts from the Jodhpur centre said from
the prominence and the width of the palaeo channels on the satellite data,
supported with data from archaeological finds, age and quality of ground water
and sediment type data it could be concluded that Saraswati indeed flowed in
ancient time with the main course passing through river Ghaggar in north
Rajasthan.
Mention about river Saraswati could be found in the Vedic and ancient literature
such as Rigveda, Brahmana and Srautasutra, Mahabharata, Ramayana, Bhagvat Purana
and Vamana Purana.
Many seats of learning and ashrams, inhabited by rishis such as Yagyavalka, were
situated on the banks this holy river. The Jodhpur centre of Isro carried out a
detailed study to map the palaeo channels to establish the course of the river.
Data from wide field sensor of IRS, which had a spatial resolution of 188 m and
a swath of 810 km, had been used for mapping prominent palaeo channels.
Imageries generated from specific areas were used to select sites over the
palaeo channels for drilling 11 borewells in Jaisalmer district to check the
ground water and the analysis of the age of ground water samples had confirmed
the presence of palaeo channels.
