Example of the grain size control of the modeled sediment distribution at the Magdalena river. a Sedimentation area decreases when grain size increases due to a faster sink relative to the horizontal advection capability of the sea currents. b Influence of the grain size on the SSD. For the Magdalena, SSD is closer to the in situ sediment discharges when grain size is around 40–50 µm (see blue and red arrows for s1 and s2 solutions, respectively) and in any case larger than 40 µm. Results at the other 12 rivers are in Supplementary Fig. 6. The hue around each GRACE solution represents the uncertainty derived from the signal (sediment) to noise (GRACE data) analysis (see Methods)
