| Abstract | The Brahmaputra River is one of the most sediment-rich rivers in the world. It presents a complex challenge for sediment transport and morphodynamic modelling. The highly dynamic behaviour is characterised by rapid channel avulsion, extensive bank erosion, and a complex braided planform. The tectonically active Himalayas supply the immense sediment load exacerbated by the heavy monsoonal precipitation. Riverine communities, infrastructure, and navigational routes are all at serious risk due to the constant large-scale morphological changes caused by this sediment flux. Such extreme dynamics are frequently not adequately represented by conventional modelling techniques. Moreover, model calibration and validation are constrained by the limited availability of field measurements during monsoon-induced flood peaks, characterised by maximal sediment fluxes and morphological activity. The current study proposes implementing resilient mathematical models to model and predict sediment dynamics in the Brahmaputra River. The study aims to improve the ability to predict large-scale morphological evolution by simulating bar development, channel migration, sediment partitioning, and erosion patterns. These findings assist in evidence-based decisions to monitor flood risks, develop sustainable infrastructure and ensure safe navigability in waterways. Ultimately, the research facilitates the development of rigorous, process-oriented modelling instruments to manage one of the planet's most dynamic and sediment-laden rivers. |
