Water Level In Brahmaputra River To Increase By 2050: New IPCC Report Claims

GUWAHATI: The river basin of the Brahmaputra that supplies water to densely populated regions of the country Bangladesh and the Indian state of Assam will witness a rise in its river run-off by the end of the 21st century.

As per the projections by IPCC (Intergovernmental Panel on Climate Change), the world's 9th largest river Brahmaputra river will experience a rise in its water level by the years 2050 and 2100.

On 28 February 2022, the IPCC projections released its sixth Assessment Report on Impacts, Adaption and Vulnerability according to which there will be a considerable increase in the river run-off. The panel fresh reports claim that the run-off in the Brahmaputra will be expanding by three to eight per cent.

According to the reports by the IPCC, the increase in the water level of the upper Brahmaputra towards the end of this century would occur because of the rise in precipitation.

The report further added that the future hydrological extremes in the upper Brahmaputra, Indus and Ganges show an increase in the magnitude of extremes by the end of the 21st century by applying RCP 4.5 and 8.5 scenarios particularly due to precipitation rise.

By the end of the century, the river run-off in the Brahmaputra is projected to rise by 16% under the climate change scenarios.

Notably, the changes in the water level in these scenarios are larger in the wet season than in the dry period. In addition, the areas of the Ganga-Brahmaputra region also face the extreme threat of high frequencies of flood-related events.

It may be mentioned that river run-off is the water that comes and joins directly into the river water system from various natural sources like groundwater, melting snow and rainfall.
