Conclusions
Obtained
results
are
from
SimulHyd hydrologic models using
a simple hypothesis of 10%
decrease in precipitation over
Niger river Basin without a
convolution with GCM output.
More rigorous modeling studies
are therefore necessary and will be
based on CMIP5 and GeoMIP5
simulation outputs using some
other hydrologic models.
