Riverbank erosion is a common geomorphological process of alluvial floodplain rivers. Bangladesh is mainly formed by alluvial deposits in which riverbank erosion very often due to regular shifting of river channels. The study area lies in north-western part of Bangladesh under Dhunat Upazila, Bogra District. Total studied area is about 248.15 km². The works aim mainly river shifting detection analyses of Jamuna River in the study area. It is carried out to know the land and river position in different time periods, mode of shifting and present bank bar position. The present investigation based on multispectral satellite imagery (SPOT, Landsat-MSS, Landsat-TM, Landsat-ETM+ Rapid Eye, Google Earth) interpretations which were used by means of ArcGIS and Erdas Imagine software followed by field check. Based on texture, tone, association, shape, size and pattern of each unit features of images and field checking. The overall trend of the present right bank line migration is in a westward direction. The right bank of the Jamuna River shifted 4.80 kilometer since 1952 to 2018 toward Dhunat Upazila at the average rate of 43.00 meters per year. The output of the present research work may be helpful to the decision makers to take the proper mitigation measure regarding riverbank erosion.
