Examines sediment transport dynamics in the Ganga River, revealing depositional environments and implications for river management.

The research aims to link grain size and geospatial indices to understand sediment transport and deposition in the Ganga River.
Analyzed sediment characteristics in the Ganga River using statistical parameters.
Employed linear discriminant function (LDF) and sediment transport index (STI) for data interpretation.
Utilized CM diagrams to identify sediment transport mechanisms.
Distinct depositional environments were identified with specific LDF values.
Rolling and suspension were found to be the dominant sediment transport mechanisms.
Minimal erosion was observed, indicating stable depositional features.

Pandey et al. (2026) studied this question.
