Nainital: The heavy snowfall and rains in the last winter season have brightened the possibilities of increasing the water level of rivers originating from the Himalayas. The initial findings of an extensive research have revealed that owing to the rains and heavy snowfall in the last winter, the glaciers will recede at a slower pace in comparison to the previous years.

A research carried out by Environment Scientist Dr Mahendra Singh Miral at three glaciers including Milam (Pithoragarh), Gangotri and Dokrani with the help of Global Positioning Technique has come up with a startling revelation. Miral opines that the glacial rivers – Gauri Ganga, Dhaul Ganga, Kali, Pinder Ganga, Ganga, Bhagirathi, Alakhnanda and Mandakini will flow with full vigour this year.

The sunrays between June and September will first melt the fresh snow, followed by the liquefying of stocked up snow in the last few months of the years. This will significantly increase the water level of Himalayan rivers, the study mentions. Whereas, owing to the poor snowfall in previous winters, the stocked up snow started melting earlier and hence the water level of rivers did not increase.

According to the initial findings, Gangotri glacier receded 13.3 metres and Dokrani 16 metres in year 2004-05 which directly affected the Indian sub-continent. The research carried out on Milam glacier (Pithoragarh) revealed that in year 2005, 44.06 crore cubic meters of water was released which contained 43.08 lakh tonnes silt.

The study further states that every year an approximate of 56.94 crore cubic metres of water is released from the Gangotri glaciers in the different rivers which also contain 17.50 lakh tonnes silt.
