Data to modeling the effects of future climate change on streamflow in Salgado River basin in the Brazilian Caatinga biome

These are the data used to evaluate LULC changes and the future water yield (WY) in the Salgado River basin (SRB) for the period from 2030−2060. Many procedures were used: (a) calibration and validation of the SWAT model is used on a monthly basis for 1986−2017, with a calibration period from 1986 to 2005 and validation period from 2006−2017, (b) LULCC analysis is performed for 1985−2000, (c) future LULC is predicted using the land change model for 2050, (d) multiple scenarios involving five global circulation models (GCMs) are simulated, and representative concentration pathways (RCPs) are considered, (e) bias correction and downscaling for precipitation, maximum temperature, minimum temperature, are performed, (f) average monthly streamflow is estimated from 2030−2060 using GCMs, (g) future hydrological modeling of the geographical distribution of the water yield is performed for each subbasin of the SRB, and (h) RCPs are compared with the baseline period from 1970−2005.
