| contents | <p>Abstract: The Moyna basin of East Midnapore, located in the lower deltaic plain of coastal<br>West Bengal, has historically been prone to prolonged floods and prolonged inundation. Prior<br>to 2010, a combination of low channel capacity, heavy sedimentation, structural barriers and<br>tidal backwash caused annual or near-annual floods lasting 15-40 days. The KaliaghaiKapaleshwari-Bagui (KKB) project (2010) was initiated in collaboration with the West Bengal<br>government and the central government as a major basin-scale intervention that included river<br>dredging, embankment strengthening, channel widening and rehabilitation of tributary<br>networks. This study critically examines the hydrological, geomorphological and socioeconomic consequences of the project using household surveys, flood records, rainfall<br>statistics, satellite observations and secondary data from the state irrigation department,<br>comparing the pre- and post-2010 situations. The findings show a significant reduction in flood<br>duration and water stagnation-typically 15-30 days before 2010 to 3-7 days after 2011, and a<br>significant reduction in flood frequency. Despite these achievements, new challenges are<br>emerging: rapid sediment deposition in low-lying areas, tidal barriers, persistent man-made<br>barriers (bamboo bridges, fishing nets), and reduced transport capacity in distributary rivers.<br>The paper argues that the KKB project has successfully reduced the risk of major floods, but<br>its long-term sustainability depends on continued dredging, improved sediment management,<br>catchment-wide planning, and community-cantered water management strategies.
