Abstract:Sediment flows dynamics (erosion, transport and deposition) have been
disrupted in South America (SA), a continent with the highest erosion
and sediment transport rates globally. However, the magnitude and
spatial distribution of the main drivers of changes have been poorly
identified and explored. Here, we performed simulations using a
hydrological-hydrodynamic-sediment model to comprehensively estimate the
spatial and temporal sediment changes and trends in SA from 1984 to
2019. We found that 51% of the main… Show more
