Correcting drawdown: The Cooper-Jacob method
---------------------------------------------

Here we demonstrate the correction established by Cooper and Jacob in 1946.
This method corrects drawdown data for the reduction in saturated thickness
resulting from groundwater withdrawal by a pumping well and thereby enables
pumping tests in an unconfined aquifer to be interpreted by methods for
confined aquifers.
