How much water an aquifer stores or releases per head change

Storativity (or the storage coefficient) is the volume of water an aquifer releases from or takes into storage per unit surface area per unit change in hydraulic head; in a confined aquifer it reflects the elastic compression of the water and the porous matrix. Jacob's 1940 On the flow of water in an elastic artesian aquifer derived how this elastic storage governs transient groundwater flow and the drawdown around a pumping well. The referent is a dimensionless storage property of an aquifer that, together with transmissivity, sets how head responds to pumping or recharge.[1]

Unit
Dimensionless volume of water released per unit aquifer area per unit change in head
Recovery means
Not applicable
Measured by
Estimated from the time-drawdown response in aquifer pumping tests (Theis or Cooper-Jacob analysis)
