A team of researchers and experts have found an undiscovered dried-up river during the geophysical survey in the Kaushambi and Prayagraj region in Uttar Pradesh. The most important aspect of this discovery is that this river was a link between Ganga and Yamuna rivers.

The Union Jal Shakti Ministry wants to develop this river as a potential groundwater recharge source. A team of researchers and scientists from the CSIR-NGRI (National Geophysical Research Institute) and the Central Groundwater Board found this river.

About ‘ancient river’ found in Prayagraj

• A remnant (Palaeochannel) of an inactive river shows was found about 26 km south of the current Ganga-Yamuna confluence at Prayagraj.
• It was found that the buried river was a link between Ganga and Yamuna rivers.
• It was found during the discovery that it was about 4 km wide and 45km long river. The remains of the river were found under a 15-meter-thick layer of the soil.
• The report also suggested that the mythological Saraswati River actually existed.
• S. Valdiya Committee has prepared a detailed report on palaeochannel on North-West India.
• Experts said that the river was the lifeline of the North-Western states of India.

What is Palaeochannel?

• A Palaeochannel is a remnant of a buried or an inactive river. In other words, it is a channel which is not a part of an active river system.
• It happens when rivers are dried-up due to various natural or man-made situations.
• A river also changes its course when severe floods cut the previous route of the river. Also, movement in tectonic plates affects the route of the river.


This discovery will play a very crucial role in the planning of Ganga cleaning and protecting safe groundwater resources. It is also important because it will give a new aspect to understand the present day scenario of Ganga-Yamuna Rivers. It will be helpful for researchers to map North-West India’s rivers with a new perspective.
