Question

What makes Bihar the most flood-prone state among all north Indian states?

Answer 1

Bihar is the most flood-prone state among all north Indian states because many of the rivers flowing through Bihar, such as the Kosi, Bagmati and Gandaki, flow through the high mountainous region of Nepal, before crossing very small distances and rapidly reaching the plains of Bihar, making them far more forceful. When it rains heavily in Nepal, the extra water enters these river channels and rushes into the plains of Bihar. As the rivers break their banks and overflow into the adjoining areas, large area of land and thousands of people and livestock are affected. More than 76% of the population in Northern Bihar live under the threat of floods every year.
