Simulated Suspended Sediment Discharge for South America Rivers (MGB-SED AS) - V2.0
We provide a new dataset of simulated suspended sediment discharge for South American rivers using daily hydrologic-hydrodynamic modeling. From the previous version (10.17632/k7c5482fsm.1) we improved our results by simulating 234 large reservoirs in South America and also by considering 8 land use and land cover maps. We also extended our simulated database from 1984-2019. In this version, we simulated both suspended (QSS) and bedload discharge (QST), considering new sediment processes like sediment trapping in reservoirs. The simulated data from the model MGB-SED AS was validated against observed water discharge, reservoir outflows and volumes, and suspended sediment. We also compared our bedload estimates against the results from the estimates of some regional studies. The data provided for us are: - NetCDF file named 'QSS_1984-2019.nc' with daily suspended sediment discharge (t/day) for all (33749) simulated river reaches from 1984-2019. - NetCDF file named 'QST_1984-2019.nc' with daily total sediment discharge (t/day) for all (33749) simulated river reaches from 1984-2019. - shapefile named "Annual_Sediment_Discharge_MGB-SED_AS.shp" with annual suspended and total sediment discharge (t/year) for all (33749) simulated river reaches from 1984-2019 and their respective drainage areas. - .rar file with C, K and LS MUSLE parameters
