Additionally, as a
consequence of reduced groundwater levels, streams
in upland areas, can expected to have lower seasonal
flows, thus having significant adverse impacts on
large headwater wetland systems. The ability of a
groundwater flow model to predict changes to
groundwater levels, as forced by climate change,
depends on the locations and types of model boundary
conditions, the success of model calibration and
model scale (Scibek and Allen 2006).
