Empirical evidence continues to show that climate change remains a threat to the stability
of the hydrologic system. As the climate system interacts with the hydrologic cycle, one significant
repercussion of global warming includes changes in water availability at both regional and local scales.
Climate change adaptation is intrinsically difficult to attain due to the dynamic earth system and
lack of a comprehensive understanding of future climate and its associated uncertainties. Mostly in
developing countries, climate adaptation is hampered by scarcity of good quality and adequate hydrometeorological data. This article provides a synopsis of the modelling chain applied to investigate the
response of the hydrologic system under changing climate, which includes choosing the appropriate
global climate models, downscaling techniques, emission scenarios, and the approach to be used
in hydrologic modelling. The conventional criteria for choosing a suitable hydrological model
are discussed.
