Effect of climate change on river Kosi and its basin
Considering the vulnerability of the Kosi's basin, the melting glaciers will acerbate the problem a hundredfold. The melting glaciers will release much more water than normal in a short time thus creating a flood situation.

Kosi is one of Ganga's largest tributaries and in turn is fed by 7 tributaries - Sun Koshi, Dudh Koshi, Indravati, Tama Kosi, Likhu, Arun, and Tamar. These tributaries encircle Mt Everest from all sides and are fed by world's highest glaciers. The river drains a total area of 69,300 sqkm upto its confluence with Ganga. The river basin stretches 54,000 sq.kms.
Effect of climate change on the Ganga-Brahmaputra delta regions
The Ganga-Brahmaputra-Meghana delta belt comprises of 105,000 sq. kms of which 2/3rds is in Bangladesh. The Ganga-Brahmaputra-Meghana system has the largest catchment area of 1,100,000 km². The delta region is particularly vulnerable to seasonal floods, heavy run-offs from melting snows, and tropical cyclones in the Bay of Bengal. Inspite of this, it is one of the most thickly populated regions on Earth.

The delta belt is home to approximately 125-140 million people. And over 300 million people are supported by the delta. The density of population in the Delta region is 200 people / sq.km. making it one of the densest regions in the world.

The delta region is a high-rainfall region and receives 60-80 inches of rainfall every year.

The Indo-Gangetic Plains, formed by the drainage systems of the rivers Indus and the Ganga, stretch across the countries of Bangladesh, Nepal, India and Pakistan covering approximately 401.72 million hectares of land.
Impact of climate change on river deltas and other coastal areas in India
While global warming is a matter of worldwide concern, among the most vulnerable areas are the coastlines of less developed tropical countries such as India. The river deltas, in particular, are already facing the brunt of climate change and these adverse impacts can be expected to increase dramatically in the course of this century.
