The Jamuna River exhibits significant erosion along its banks, resulting in changes to its course and posing challenges for local communities. This study aimed to detect the changes of Jamuna River flow path and to estimate the rate of change of flow area, erosion, and accretion along the Jamuna River for the period of 1990 to 2020. Landsat satellite images of 30 m resolution from 1990 to 2020 at five years interval were collected from USGS website. River flow area and bank lines were detected from raster calculation of MNDWI. The rate of bankline shifting and bankline movement were computed in LRR (m/year) and NSM (m) method respectively. The Jamuna River had consistently lost its water body at an average rate of 4.6 km2 per year from 1990 to 2000. However, the river's flow area remained relatively stable, with an average annual decrease of 0.35 km2 during 2000-2020. The upstream areas of Kazipur and downstream areas of Nagarpur and Shahajadpur were identified as the most vulnerable regions. Conversely, the middle segments of Sirajganj Sadar and Bhuapur were relatively stable. The area downstream of Jamuna Bridge has experienced significant land gain, with a maximum width of 4.2 km. On average, the right bank of the river experienced an erosion rate of -11.97 m/year, while the left bank eroded at an average rate of -52.44 m/year. This study advocates for policymakers to mitigate the risk of Jamuna riverbank erosion and implement sustainable management strategies.
