A team of scientists from Hyderabad-based CSIR-National Geophysical Research Institute (NGRI), led by former director and scientist Virendra M. Tiwari, on Monday unveiled a 3D aquifer map of 10,000 sq.km area of Ganga-Yamuna ‘doab’ between Prayagraj and Kanpur. The scientists say it will be useful for the management and augmentation of groundwater resources in the region.
The team had carried out the aquifer mapping with advanced heliborne geophysical technologies, and the results were validated through ground-based measurement and drilling. The study further showed hydrogeological linkages among a ‘paleoriver’ (an ancient river), the Ganga and the Yamuna with an underlying aquifer system, said Dr. Tiwari.
These hydrogeological connections between two existing and an ancient river makes them a unified system, which may facilitate exchange of water as well contaminants, he pointed out.
