Abstract: This paper examines the morphological evolution of the Char lands of the Padma River and its impact on the planform morphology of the Padma. Drivers of the morphological evolution are also investigated in this paper. The study utilizes geospatial data derived from remotely sensed images taken between 1962 and 2022. Development through huge accretion and erosion in the Harirampur Char, repeated movement of Amirabad Char from the left bank to the right bank, and straight geomorphological connectivity between Paler Char and Chhitar Char were the main occurrences in the Char lands of the Padma. We see that among all the Char lands, the rate of expansion of Harirampur Char and the erosion rate in the banks around the Char were mutually related in a half-decadal delay mode. The Char lands of the Padma are seen to have morphological connectivity with the banklines around them and, in some cases, with the other co-existing Char lands. Due to this connectivity, the cyclic evolutions of Char lands contributed to the repeating channel pattern of the Padma. Dynamics of the Ganges-Jamuna confluence and the high-magnitude floods enhanced the morphological changes in the Padma.
