Buried-valley aquifers respond differently to pumping compared to other types of aquifers. Pumping from these aquifers causes larger and more widespread drawdown effects. Traditional theories for aquifer flow do not apply well to these narrow strip aquifers. New research has reviewed previous theories and developed a practical method for analyzing pumping tests in these aquifers. A case study in southern Saskatchewan, Canada, showed that these aquifers experience unusually large drawdowns when pumped. This information is important for managing groundwater resources in buried-valley aquifers.
