چکیده:

Kopotaksho Basin Area (KBA) is under the peril of water-logging due to the natural (changing river geometry, channel migration and abandonment) and human interventions (construction of bridges and sluice gates, use of unsustainable fishing gear). The analysis of satellite images revealed that over the years water-logging problem had been increased significantly. The water-logged area in 1999, 2000, 2003, 2006 and 2008 was about 8.65, 12.87, 12.24, 11.72 and 19.47 km2 respectively. Indigenous coping practices (abode amendment, floating, ring gardening, rainwater harvesting, upliftment of tubewell platform, community based latrine) were observed in the water-logging affected area. Locally acceptable concept, Tidal River Management (TRM) with local people’s participation was identified as a feasible long-term remedial option to diminish water-logging coverage at the KBA
