Come May and the wild river of the east is seized with spells of unrelenting spate, attendant deluge, sediment deposition and erosion.
The flood hazard has been ravaging upper Assam unabatedly since time immemorial. Explorers of ancient times – those who established Praagjyotishpur in Kamrup province – must have discerned in this river something very different from all other rivers of the subcontinent, as evident from the singularly masculine name they gave it – ‘Brahmaputra’ or ‘the son of Brahma’.

jatinder, Be an eyewitness, and add photos of your investigative efforts. Good stuff.
The author concludes with some possible solutions that might help:
" .. building of embankments and drainage channels in
upper Assam would not bring lasting relief from flood hazards.
The solution lies in channelizing discharge of the order of 48,160 m3/s of
the Brahmaputra through canals, aqueducts, tunnels, etc. across the
northward prolongation of the Meghalaya block, particularly between
Guwahati and Hathimura and other places (west of Mikir Hills) where
identified active faults cross its channel.
The
canals would have to be deepened periodically in order to keep pace
with the rate of uplift of the block. Absence of channelization of the
Brahmaputra
in spate would always cause ponding, leading to deposition of
sediments, reduction in carrying capacity and inundation of the flood
plain. In my opinion, this is what is happening to- day. It will
therefore be advisable to embark on a comprehensive multidisci."
