Bangladesh is a riparian country that is criss-crossed by the many tributaries and distributaries of the mighty Ganges, Brahmaputra, and Meghna river systems. Gorai-Madhumati, a distributary of the Ganges River is an example where morphological development of the river is associated with frequent channel shifting within the catchment area. The main objective of this research is to quantify the extent of channel migration, erosion-accretion, river width, sinuosity, and charland morpho-dynamics from 1972 to 2018 using geospatial techniques combined with satellite images and hydrological data. The study also addressed the impacts of Farakka Barrage construction in India on the shifting, flow behavior, and siltation of Gorai-Madhumati River. The study shows that bar surface areas have abnormally increased in both segments after 1975 due to the construction of Farakka Barrage. Water flow in the Gorai-Madhumati has dropped remarkably in the downstream and instigated huge sedimentation in this region. Analysis of the time series satellite images revealed that the morphology of the river channel experienced huge changes simultaneously with the changes in the seasonal flow and sedimentation all over the study period. Migration trend has frequently shifted and taken place in the NW and NE direction in the observed sections of the river. Throughout the study period, total amount of accretion was greater than the net percentage of erosion on both banks of the river. River discharge, bar accretion, and erosion history show that the Gorai-Madhumati River will no longer exist with the present flowing condition without attention and proper river management.

孟加拉国是一个沿河国家，到处都是强大的恒河，雅鲁藏布江和梅格纳河系的众多支流和支流。恒河的一个分支Gorai-Madhumati是一个例子，其中河流的形态发展与集水区内频繁的河道转换有关。这项研究的主要目的是使用地理空间技术结合卫星图像和水文数据来量化1972年至2018年期间河道迁移，侵蚀积聚，河宽，河床弯曲度和夏兰形态动力学的程度。该研究还探讨了印度的法拉卡（Farakka）拦河坝建设对Gorai-Madhumati河的转移，流动行为和淤积的影响。研究表明，由于法拉卡（Farakka）弹幕的建造，1975年以后，这两个部分的钢筋表面积均异常增加。Gorai-Madhumati的水流量在下游显着下降，并引发了该地区的大量沉积。对时间序列卫星图像的分析表明，在整个研究期间，河道的形态发生了巨大变化，同时季节性流量和沉积物也发生了变化。迁移趋势经常在被观察河流的西北和东北方向发生变化和发生。在整个研究过程中，河床两岸的积聚总量都大于侵蚀的净百分比。河水排放，酒吧积水，
