Floods of Jalangi and Mathabhanga-Churni Rivers along with the floods of Bhagirathi River played a key role in the delta-building processes of Nadia and Murshidabad districts. Floods of these rivers have boosted the health of soils and water bodies of the region. Floods have also a significant effect on the productivity of soils and water bodies. Events of (1) neotectonics and subsequent eastward tilting of the Bengal basin, (2) eastward flight of the Padma River leaving behind its distributaries, (3) formation of huge sandbars at the offtakes of these rivers restricting the entrance of water from the Padma, and (4) post-Farakka lowering of the water level of the Padma River in comparison to bed level of these distributaries have changed the flood scenario significantly. Now there is no flood like before, except for the deluge of 2000. However, the evil effects of normal floods have been multiplied as the side effect of several structural or hardware solutions against floods. Living with floods is suggested.
