Dear Raj,Root cause for continuous flood in Bihar is excess water release from Nepal which shares most of the rivers coming to the state.Well we cannot blame Nepal either which is doing its best for their own people.There is long pending Dam construction issue for River koshi.It has been negelected by the centre for decades.Who cares?They were busy making Dams in Punjab because they cried most.Ultimately Punjab paid them back with seperate nation demand.Hope state govt of Bihar under Nitish kumar prepares well for next years flood which is bound to happen again.
