Chandigarh, India: Haryana State Space Application Centre (HARSAC) in Hisar, India, prepared palaeochannel maps of five districts Panchkula, Yamunanagar, Ambala, Kurukshetra and Kaithal by using data from remote sensing satellites.
“Palaeochannels are the remnants of the pre-existing rivers which were buried or extinct due to geological (tectonic) or climatic activities,” a spokesman of HARSAC said. The northern part of the state comprising the piedmont zone covering mainly Panchkula, Yamunanagar, Ambala, Kaithal and Kurukshetra districts have good drainage network, which indicates that there might have been more number of drainage systems in the past.
“In order to harness the potential of these old drainages/palaeochannels, a study has been conducted by HARSAC with an objective to identify and delineate the abandoned river courses/palaeochannels using data from remote sensing satellites,” he said.
In addition, a geophysical survey at limited sites in the mapped area was also undertaken with the help of Kurukshetra University to verify the existence of these palaeochannels and for ground water characterisation in the identified palaeochannels.
