GS-II: Scientists find ‘ancient river’ in UP.

News

The Union Water Ministry has excavated an old, dried-up river in Allahabad that linked the Ganga and Yamuna rivers. The “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 Allahabad. The paleochannels reveal the course of rivers that have ceased to exist.

Significance of this river:

Knowledge on subsurface connectivity between Ganga and Yamuna rivers will play a very crucial role in planning of Ganga cleaning and protecting safe groundwater resources.
The aim is to develop it as a potential groundwater recharge source.
The evidence from paleochannels also suggests that the mythological Saraswati river did indeed exist.
