Predictable floods will occur in Brahmaputra soon

A new study has claimed that the Brahmaputra river would have devastating floods sooner than previously estimated. This situation will occur when the impact of human activities on climate is not included in this assessment.

The basis of this claim in the study is the analysis of the river flow in the last 700 years. According to the research paper published in the journal 'Nature Communication', the long-term minimum flow in a river in Tibet, Northeast India, and Bangladesh are much higher than earlier estimates.

Scientists involved in the study, including scientists at Columbia University, said that it was previously estimated that the natural difference in the minimum flow of the river and the main water level has been calculated since the year 1950. Scientists say that the current study is based on three-tier data. According to this, the earlier estimate is 40 percent less than the new estimate.

Mukund P Rao said that whether you consider climate model or natural variability, the message is the same. We have to be prepared for the floods to happen very quickly, contrary to current estimates. Rao and his comrades tried to find out how large scale floods can occur in the future.

He analyzed the average flow of the river in north Bangladesh, which was 41,000 cubic meters per second between 1956–1986. The drift increased to 43,000 cubic meters per second between 1987–2004.
