Geographia Technica, No. 2/2007, pp. 1 - 11 STUDY OF MORPHOLOGICAL CHANGE OF RIVER OLD BRAHMAPUTRA AND ITS SOCIAL IMPACTS BY REMOTE SENSINGJ. B. Alam, M. Uddin, J. Uddin Ahmed,H.Cacovean, M. Habibur Rahman,B. K. Banik, N. YesminABSTRACT - Old Brahmaputra River is one of the main rivers in Bangladesh. In this study, the part of the old Brahmaputra River, offtaking from Jamuna is located under the district of Mymensingh and partially under the district of Tangail, Jamalpur, Sherpur and Netrokona. Analyzing the image of part of the old Brahmaputra River among the year 1997 and 2004, it is found that Significant changed has been occurred in north east part of Mymensingh sadar upazila and less change is found in the lower part which is close to the Mymensingh town where China Bangladesh Friendship Bridge (Shambhuganj Bridge) has been constructed. Transportation of sediment is the major contributing factor of morphological changes. Keywords: meandering, remote sensing, sediment transport, morphological changes,river protection.
