Ghaggar flows in Saraswati’s place

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.
