Abstract

The old Brahmaputra, Dasani, Jinjiram, Alaikhal, and some other distributary channels of Jamuna flow through Jamalpur. Old Brahmaputra and Dasani rivers are hydro-morphologically dynamic, erodible, and meandering. There is a precedent of two rivers meeting in the Jamalpur district. In 2009 near Sherpur Sadar, Old Brahmaputra and Dasani rivers were conflicted. After that conflict in 2009, about 4 km length of the Old Brahmaputra River and 14km length of a branch channel of the Old Brahmaputra River name Jhinai lost their existence. Generally, one river will pass more flow than the other after meeting two rivers. More flow rivers will face bank erosion, shifting, and hydro-morphological change. On the other hand, less flow of the river will be silted on the river bed. There will be a probability of conflict between the Old Brahmaputra River and Dasani River again near Baksiganj upazila in Jamalpur district. Because the present distance between the two rivers bank is only 340m and they are getting closer day by day. Landsat Satellite images for the years 1985, 1990, 1995, 2000, 2005, 2010, 2015, 2020 and 2023 have been collected based on the study area from USGS Earth (earthexplorer.usgs.gov). ERDAS IMAGINE 2014 and ARC GIS 10.3.1 have been used to analyze the satellite images to understand the morphology and planform of the river. This study has assessed the probability of future conflict between the Old Brahmaputra and Dasani rivers using past morphology, planform change and present trend of river bank shifting. The effect of to merging of rivers on people’s life, livelihood, and the river system in Jamalpur district has also been assessed. Remedial measures have been recommended to sustain Jamalpur’s people’s life, livelihoods, and river system.
