Riverbank erosion, one of the major natural disasters in Bangladesh, causes untold misery every year to thousands of people living along the banks of the rivers of Bangladesh. Bank erosion alone has rendered millions homeless and has become a severe social hazard.
Since 2004, predictions for morphological changes have been conducted for the Jamuna River, followed by the Ganges and the Padma. Thus, it has been 22 years since predictions were made available to national-level stakeholders. Evaluation of the predictions for the last few years shows a reasonably good match with the occurrences. It is to be mentioned here that CEGIS has updated the existing prediction tools for the Jamuna, Padma, and Ganges rivers by analyzing good-quality long-time series images and by categorizing particular shapes of sedimentary features in 2017, as river morphology is changing over time, with changes in river planform due to natural and human interventions. Over the past several years, these methods of predicting morphological changes and bank erosion were successfully applied in a number of BWDB and WARPO projects, including the RBPP, JMREMP, FAP 21, Monitoring of the BWDB Training Project and EMIN. The results of the applied method are in good agreement with field observations.
