The objective of this study is to assess the impacts of future
climate change on seasonal average discharge and monthly water
budget in a small headwater catchment, located on the Grande River
basin, in Minas Gerais, Brazil. The assessment is carried out
using the hydrology model, DHSVM. The atmospheric forcing to drive
the Distributed Hydrology-Soil-Vegetation Model (DHSVM) is derived
from the downscaling of the HadGEM2-ES projections by the Eta
Regional Climate Model, at 5-km high resolution. The projections
assume the RCP4.5 and RCP8.5 IPCC AR5 emission scenarios. Baseline
period was taken between 1961 and 1990. The projections are
assessed in three time slices (2011-2040, 2041-2070 and
2071-2099). The climate change is assessed in time slices of 30
years and in comparison against the baseline period to evaluate
the hydrological changes in the catchment. The results showed
differences in the hydrological behavior between the emission
scenarios and though time slices. Reductions in the magnitude of
the seasonal average discharge and monthly water budget may alter
the water availability. Under the RCP4.5 scenario, results show
greater reductions in the water availability in the first time
slice, whereas under RCP8.5 scenario greater reductions are
indicated in the third time slice.",
