Assessing the long-term planform dynamics of Ganges–Jamuna confluence with the aid of remote sensing and GIS

The confluence of the Ganges, Jamuna, and Padma rivers is one most dynamic in world, an internationally important research area because two world's major rivers, Ganges Brahmaputra. Morphological changes this have resulted severe erosion along banks. Riverbank Bangladesh's critical issues, requiring a substantial solution. affects millions people Bangladesh each year zone. Consequently, understanding morphological shifting pattern crucial. aims to quantify actual bank near terms rate during 25-year period (1990–2015). acquired satellite images were geo-referenced, lines digitized carry out research. line linear construction that separates outside boundary river channel from floodplains. To assess width fluctuation, distance between extreme borders left right banks, including mid-channel sandbars, was measured. This split into five stages, lasting 5 years, measure maturity change. Furthermore, long-term trend 1972 2015 qualitatively discernible. Landsat pictures used investigate study provides current reliable information on planform dynamics Ganga–Jamuna confluence. will help design implement drainage development plans control techniques crucial
