Abstract

Bank erosion is a common hazard in middle course of Brahmaputra River. Bank instability mapping is an important element for planning in bank erosion affected area. Taking Goalpara district of Assam as an example, a land loss map is carried out using available satellite data and data from governmental agencies. The assessment of bank erosion in Goalpara district part of Brahmaputra River is done using Geo spatial tools. It is found from the assessment that 59 km2 areas are loss through bank erosion in Goalpara district part of Brahmaputra River during 1970-2010. Therefore, the study area can recognize as high risk location of bank erosion and need specific planning and development for reinstate the problem.
