Determination of unsteady radius of influence during pumping from confined aquifers

Abstract
In case of pumping from a confined aquifer at a dynamic water level located above its roof, during the period of unsteady water inflow to the borehole, the pumped water is obtained at the expense of “elastic storage” (an aquifer not communicating with other aquifers or surface water bodies within the area of the cone of depression). “Elastic storage”, according to V.N. Shchelkachev, is the volume of water displaced into the well during elastic expansion of water and water-bearing rocks due to pressure drop in the area of the cone of depression.
