Rumki Sarkar, Pankaj Sarkar, Ganesh Biswas

Abstract: Channel shifting is very common aspect of the flood plain environment all over the world. Bank erosion is the immediate effect of channel shifting. A rapid rate of river bank line shifting is found in the study area. The changing character of land use is being accentuated due to river bank erosion or channel shifting. In this study, the changes in Land use and Land Cover (LULC) driven by bank erosion were studied using P.S map and Google Earth map. The present study is mainly oriented towards the morphometric measurement of river through temporal changes during 1937, 2019 P.S map and Google Earth map data. In this paper an attempt has been made to get the nature of shifting, direction of shifting, sinuosity of the river channel has also been calculated.

Keywords: Channel migration, sinuosity, river reach, meander belt
