Dr. Nibedita Das, Moujuri Bhowmik

Abstract :

In Jirania R.D. Block, a large number of people are threatened by erosion hazard of both the banks of the River Haora. Here two villages namely, Rabicharan Thakur Para and Golak Thakur Para, with two sites each have been identified as most vulnerable places. Main objective of this study is to carry out the qualitative assessment of bank erosion through Bank Erosion Hazard Index (BEHI). Bank erosion variables considered for BEHI ranking include bank height ratio, root depth ratio, weighted root density, bank angle, surface protection and bank material. About 14.09 acre area has already been lost. Here the rate of bank erosion is 2.82 m/year. People have lost their houses, agricultural lands and had to build their houses elsewhere. But these newly built houses are again under threat of such hazard. Therefore, bank erosion hazard at these sites need proper attention for protection measures.
