Monsoon floods play a major role in shaping river geomorphology in the Indian subcontinent.
Monsoon-driven floods dramatically increase river flow and current velocity in South Asia. Juvenile and even adult gharials can be displaced downstream over long distances during extreme events. While natural flooding historically redistributed individuals and maintained gene flow, modern dams alter these patterns unpredictably. Flood pulses may now coincide with artificial barriers that trap displaced animals. Sudden relocation can separate individuals from established territories. In extreme cases, displaced gharials enter unsuitable habitats. Seasonal water surges therefore represent both ecological process and modern risk.

Natural river dynamics once integrated flooding into life cycles. Downstream movement allowed colonization of new stretches. Fragmented rivers now transform floods into disorientation events. Displaced individuals may encounter intensified fishing pressure or degraded habitat.
Climate change projections suggest more extreme precipitation events in some regions. Increased flood intensity could amplify displacement risk. Adaptive river management must consider these hydrological realities. For the gharial, seasonal water that once sustained connectivity now interacts unpredictably with infrastructure.
