Why are river plains of India prone to floods?

Heavy rains lead to a rise in volume of the river load, which causes change in river course. As a result of this, water spills over into adjoining areas which are not able to drain this water out and thus get flooded. North Indian Rivers such as Damodar, Kosi, and Brahmaputra are known for their proneness to floods.

Soil moisture too depends on groundwater. “This buffering capacity of groundwater to droughts and floods depends on the properties of aquifers and the status of groundwater extraction.
