The Union Water Ministry has excavated an old, dried-up river in Prayagraj (formerly Allahabad) that linked the Ganga and Yamuna rivers. The aim is to develop it as a potential groundwater recharge source.
About:
This “ancient buried river” is around 4 km wide, 45 km long and consisted of a 15-metre-thick layer buried under soil.
The newly discovered river was a “buried paleochannel that joins the Yamuna river at Durgapur village, about 26 km south of the current Ganga-Yamuna confluence at Prayagraj. These paleochannels reveal the course of rivers that have ceased to exist.
Evidence from palaeochannels suggested that the mythological Saraswati river did indeed exist.
The discovery was made last December by a team of scientists from the CSIR-NGRI (National Geophysical Research Institute) and the Central Groundwater Board.
