The sediment changes in the Brahmaputra have led to increased flood inundation and altered river channels, posing risks to communities downstream. In the Godavari, reduced sediment flow threatens the delta's stability, making it more vulnerable to erosion and rising sea levels. These disruptions could impact agriculture, hydropower, and flood management, affecting millions of people who depend on these rivers for their livelihoods. The findings highlight the need for integrated planning to address both natural and anthropogenic pressures on river systems.
