The Ganga river carries a lot of sediment, and researchers studied how much sediment is moved by different river flows. They found that moderate river flows are the main drivers of sediment transport. Most of the sediment is moved by river flows that happen every few years. The amount of sediment carried by the river is often underestimated or overestimated, which can affect how much sediment is actually being moved. The frequency of data collection doesn't change how much sediment is moved by the river.
