In the present study, river Jiadhal is one of the main sub-tributary of the River Brahmaputra in the Dhemaji district of Assam that changes its channel course frequently due to bank-erosion and sediment-deposition in the intermediate part and lower course of the channel. A study on the changing course of the river Jiadhal was carried out using satellite imageries for the years 1987, 1997, 2007 and 2017. The study found that the changes in the river vary from time to time and the bank-erosion and sediment-deposition fluctuate from place to place.  The total area of bank-erosion is 13.34 km 2 from 1987 to 2017 and the total area of sediment-deposition is 14.59 km 2 from 1987 to 2017. This paper evaluates how the shape, size and position of the Jiadhal River have changed from the years 1987 to 2017 using remote sensing and GIS techniques. The study is also necessary for effective management along the side of the river Jiadhal to control bank erosion and to mitigate the adverse impact of erosion and channel-shifting. application/pdfBank ErosionSediment DepositionChannel ShiftingJiadhal RiverRemote SensingfolyóiratcikkOpen AccessActa Geographica Debrecina Landscape & Environment serieshttps://doi.org/10.21120/LE/18/1/2Acta Geographica Debrecina Landscape & Environment series118Landsc. environ.1789-7556
