Question

What is the reason for flood in bihar up and assam ias?

Answer 1

Reason for flooding. Geographically Nepal is a mountainous region. When heavy rains occur in the mountains of central and eastern Nepal the water flows into the major drainages of Narayani, Bagmati, and Koshi rivers. As these rivers cross into India they flow into the plains and lowlands of Biharand break their banks.
