We provide a dataset of simulated suspended sediment discharge for South America rivers using daily hydrologic-hydrodynamic modeling. We simulate the potential natural situation, where rivers are no damming, and therefore, sediment is not trapped. The model MGB-SED AS was calibrated and validated against 595in-situ sediment stations from three national datasets: Brazilian, Argentinean, and Colombian. We also compared our results against regional studies and a global model.
The data provided by us are:
– NetCDF file named ‘QSS.nc’ with daily suspended sediment discharge (t/day) for all (33749) simulated river reaches from 1992-2009.
– shapefile named “QSS_MGB-SED_AS_annual.shp” with annual suspended sediment discharge (t/year) for all (33749) simulated river reaches from 1992-2009 and their respective drainage areas.
– shapefile named “stations.shp” with the lat long for each in-situ sediment station, domain, drainage area, and simulated river reaches ID (UnitCat).
