When a well is pumped, water flows into the well from the surrounding aquifer because of difference in hydraulic heads at the well and in the aquifer caused by pumping. Before pumping, water level in the well stands at a height theoretically equal to the static water pressure in the saturated layer around the well. Source: Roscoe Moss Company, Drawdown is always maximum at the pumping well and it decreases with an increase in the distance from pumping well Fig. The rate of pumping from an aquifer significantly affects the hydraulic gradient in the aquifer.

The solution is suited to aquifers having a semi-infinite vertical extent or to packer tests with aquifer horizontal boundaries far enough from the tested area. The problem reduces to a system of dual integral equations DE and further to a deconvolution problem. View via Publisher.
