Satellite Remote Sensing Techniques to Unearth the Lost Sarasvati River & its Palaeochannels

Dr. B.K Bhadra from ISRO presents detailed multi resolution satellite studies of the river Saraswati in northern Haryana. He discusses the specifics of the remote sensing techniques, including satellite imagery, used to study the paleo channels of the river and related analysis. In his present research, he focuses on high resolution optical and microwave satellite data in delineating the paleo channels in Haryana and Punjab as well as the Sarasvati delta structure in the Rann of Kutch to present an integrated map of the Sarasvati paleo channels. He presents material to show that paleo channels have also been validated through collateral ground data such as published maps during British and Mughal periods, as well as paleo geomorphic structures, hydrological parameters and radiometric ages of river sediments. By considering evidence from archaeology as well and the spatial distribution of the Harappan settlements, Dr. Bhadra presents how the entire course of the river Sarasvati has been delineated and the growth of Indus-Sarasvati civilization studied from these disciplinary perspectives.
