ANALYZING RIVER BANK EROSION VULNERABILITY OF SADIYA REGION, ASSAM, INDIARatul Das and Barnali GogoiAbstract The most common and regular hazards of fluvial environment are flood and associated erosion. Floodplains are densely populated areas and as such people living in these areas are exposed to these hazards. The channel migration zone has become an important tool in the US to identify the areas at risk of flood and erosion. Vulnerability on the other hand is determined by a number of factors like demographic, social, economic and environmental. These concepts are combined together to analyse the vulnerability to flood and erosion in Sadiya, a highly flood prone area of Assam. It has been found that 20 per cent of total population of Sadiya subdivision lives in the channel migration zone. The social and economic characteristics of the population make them differently vulnerable to these hazards. |
