Flood is a high flow of water which overtops either the natural or the artificial banks of a river channel.

The Topography of Bihar is marked by several perennial and non-perennial rivers, originating from the Mountains of Himalayas. These rivers carry high sediment loads that are deposited on the Bihar’s Plains. Also, Bihar is one of the climate-sensitive states in India. Bihar receives maximum rainfall during the southwest monsoon, lasting from June to September. Consequently, the onset of the monsoon in Bihar causes flood-like situations, especially on the northern plains of Bihar. Besides, climate change and global warming increase the frequency and intensity of both the floods and droughts in Bihar.
According to the government of Bihar Flood Management Information System Cell, the floods in Bihar can be divided into four categories.
Geographically, 73.63% of the area of north Bihar is prone to floods. Out of 38 districts of Bihar, 28 districts are affected with floods which cause a huge loss of property, lives, and Infrastructure. Out of 28 flood-affected districts of Bihar, 15 districts are worst affected. As per Rashtriya Barh Aayog (2006), it has been estimated that about 24% of the total flood-affected population of India resides in the flood plains of Bihar.
In the Years of 1978, 1987, 2002, 2004, 2007 and 2008, Bihar witnessed a high magnitude of floods. The floods in Bihar during July to September 2019 affected 13 districts.
