The flood situation in Assam is worsening day by day as the death toll today surged to 190 and millions are affected due to this catastrophic climate calamity. As per the Assam State Disaster Management Authority’s latest report, 8,88,177 citizens in Assam are impacted in several districts of the state.
In Bangladesh, the Meghna river which merges with the Padma originates as the Barak River which flows through Nagaland, Assam, Manipur and Mizoram. The flood situation emerges as the Barak river starts flowing above the danger level due to heavy rains.
From the beginning of summer, around March, glaciers begin to melt, increasing the amount of water flowing into all these rivers. The entire Brahmaputra region receives between 1,000 and 6,000 mm of rainfall during the monsoon, which increases significantly from June to October.
In conversation with The Print Dr Ramesh Vellore and Bhupendra Singh, working as climate scientists at the Center for Climate Change Research (CCCR) at the Indian Institute of Tropical Meteorology (IITM), Pune, said that during the monsoon season between March and May Pre-monsoon rains, and the post-monsoon September rains are a major factor in flooding.
The effects of heavy monsoons and the increased volume of water due to glacial melting increase the intensity of downstream flows of rivers, often resulting in flooding, he added.
