Analyzing morphological change of River Old Brahmaputra and its social impacts using remote sensing

Abstract

Old Brahmaputra River is one of themain rivers in Bangladesh. In this study, the part of the old BrahmaputraRiver, offtaking from Jamuna is  locatedunder the district  of  Mymensingh and  partially  under the  district  of Tangail,  Jamalpur, Sherpur andNetrokona.
