Valdivia Sauchyn-2008-Ground water trends and variability in the Canadian Prairies

Groundwater could be an increasingly important water supply in the Canadian interior
with global warming and declining summer runoff; however, not enough is known about
the behaviour of groundwater under climatic variability. A network of over 33 wells is
analyzed in order to document variability of groundwater levels and their sensitivity to
climatic events. Groundwater wells are spread through the three Prairie Provinces with
median monthly groundwater level records spanning up to 40 years. The aquifers are
mostly in sand and sandstone which make them highly sensitive to climatic variations.
