  abstract = {{T}he {A}mazon {R}iver carries enormous amounts of sediment from the {A}ndes mountains, much of which is deposited in its floodplains. {H}owever, accurate quantification of the sediment sink at fine spatiotemporal scales is still challenging. {H}ere, we present a high-resolution hydrodynamic-sediment model to simulate sediment deposition in a representative {A}mazon/{S}olimões floodplain. {T}he process is found to be jointly driven by inundation, suspended sediment concentration in the {A}mazon {R}iver, and floodplain hydrodynamics and only weakly correlated with inundation level. {B}y upscaling the sediment deposition rate (1.33 +/- 0.24 kg m(-2) yr(-1)), we estimate the trapping of 77.3 +/- 13.9 {M}t (or 6.1 +/- 1%) of the {A}mazon {R}iver sediment by the {A}mazon/{S}olim & otilde;es floodplains every year. {W}idespread deforestation would reduce the trapping efficiency of the floodplains over time, exacerbating downstream river aggradation. {A}dditionally, we show that the deposition of sediment-associated organic carbon plays a minor role in fueling carbon dioxide and methane emissions in the {A}mazon.},
