Although there have been many assessments of the effect of climate change
on river flows and (to a much lesser extent) groundwater recharge, there have
been few published quantitative studies into impacts on real water resource
systems. Table 4-8 lists studies published in particular
aspects of the water sector. Rather than summarize a large number of studies—which
use different scenarios and different methodologies—this section gives
a description of a few particularly comprehensive studies.
