The Sundarbans estuary Indian part of the Ganges- Brahmaputra delta of Namkhana Island is constantly under the threat due to natural and anthropogenic causes. This demands implementation of viable management plan backed by scientific reasoning. There are continuous changes upon earth surface by a variety of natural and anthropological agent’s activities. These agents cut, carry, away and deposit the materials from land surface. Running water has higher capacity of erosion than the other geomorphologic agents. The present research Work related to Saptamukhi and Muriganga River which channel is continuously changing due to geomorphic, climatic agents and human activities influenced in the surrounded region of Present River. This changes identification is the main objective of paper with constructive suggestions for control the right side bank erosion and shifting of Saptamukhi River. An attempt has been made here, to apparatus the RS and GIS techniques of Landsat MSS 1975 and ETM+ 2013 image of river change detection using traditional to advance geographical data sources. The advances Remote Sensing data and Topographical data are to be implementing for obtaining 38 years changes results in river stream. The comparatively result explains the 38 years changes in the river bank due to various natural and manmade activities like flood, water velocity, sand excavation, removal the vegetation cover and fertile soil excavation for the various proposes of local surrounded region’s people.
