New Delhi, Dec 8 (PTI) High emission of greenhouse gases may exacerbate extreme floods in the Central Himalayas, growing by up to 80 per cent in magnitude before the turn of the century, according to a simulation study of Nepal's Karnali river.

These extensive floods, "with a one per cent chance of happening within a year, could occur once every five to ten years at the end of the century", potentially impacting densely populated areas in Nepal and India, researchers said.

Runoff from rainfall, rather than melting snow or glacier, is likely to contribute to over 90 per cent of the additional flood water, findings published in the 'Scientific Reports' journal show.

"The densely populated Central Himalayan foreland is prone to flooding, and our findings show that the intensity of extreme
