(a)&(b) Yes, Sir. A large area of the country specially the
areas lying in Ganga and Brahmaputra basins are affected by the
floods and heavy rain every year. Uttar Pradesh, Bihar and West
Bengal are the predominant flood affected states in Ganga basin
and Assam and West Bengal in Brahmaputra basin. The details of
statewise area affected in past ten years are given in Annex.
(c)&(d) The rivers causing devasting floods and excessive soil
erosion can be controlled to some extent after storage reservoirs
are constructed in upper reaches of these rivers. Investigations
for large reservoirs in Brahmaputra have been taken up.
Similarly Union Government has also taken up joint investigation
with Nepal for storage dams.
