1. Every year the monsoon comes and with it comes nature's fury in the form of floods in Assam and Bihar . The floods arrive ,displace lakes of people, destroy crops and infrastructure and kill a large number of people.  Water recedes after some time and the land emerges but devoid of life . Hordes of people again come together and try to build life again . This cycle continues.
2. While floods are natural,  ddestruction by floods is not a natural phenomenon.  it is mostly the result of human intervention to achieve their development goals.  Sone of the common causes which lead to floods include- building of human habitation on the river banks and in the flood plain area  , encroachment on wetlands,  changed cropping pattern ,deforestation in the catchment area and building embankments.

3  .Bihar is India's most flood prone state, with 76 percent population in North Bihar living under the  recurring threat of floods . on an annual basis, the floods destroyed thousands of human lives apart from livestock and assests worth millions.  North  bihar district are vulnerable to at least five major flood causing rivers during monsoon-- Mahananda, Kosi , Bagmati , burhi gandak and gandak which originates in Nepal . when heavy rains occur in Nepal , the water flows into the major rivers of nepal . when these rivers cross into india , they flow into the plains and lowlands of bihar , break their banks and cause floods.  some south Bihar district are vulnerable to floods from son, punpun and phalgu rivers . 

4. In Assam more than 39 percent of the area in the flood prone , which is one   of the reasons for annual floods in the state . The brahmaputra river is both a lifeline and threat to assam . It receives water from monsoon rains and from glacial melt as it originates from mansarovar in the Himalayas.  During the summer, the water intensifies down streams and causes floods . Bank erosion around the brahmaputraand barak rivers in another important cause for flood in Assam. Besides, the floods situation is worsensed in Assam as it receives river water flowing down from states like Arunachal pradesh and Meghalaya. 

Scientist have repeatedly pointed out the failure of the existing policy of building embankment to control floods.  

therefore,  india needs an integrated approach to manage floods and mitigate its effects.  it requires simultaneously working on issues like water management,  pphysical planning,  land use and urban development as well as conservation of nature to control floods.
